Wizzard's elbow clicks when the bolt reaches proper torque :)
it may be an underlying health problem or it could be correct GM spec. Id still see a Doctor.
Gergely Záruba yours doesn’t ?
My only wish is that you wear gloves so that you're not exposed to chemical products. Don't want my boo to get sick.
You joke but getting old sucks.
Wizard puts out more videos while we're stuck at home. Bless this man
Well explained. Mrs. Wizard asks some good background questions and does a great job with the camera. Kudos to you both
I'm so disappointed the Wizard didn't taste that vintage trans fluid!
I was sooo hoping he would.
@@gavinplunkett977 73 was a very good year. Fewer additives.
It's for beat the best he didn't,last guy to taste vintage trans fluid is no longer alive.
I use 3M spray adhesive on gaskets
Before pulling the pan , I use a transfer pump , feeding the uptake hose down the dipstick tube .
You can pull most of the fluid out of the pan before you pull it.
I use it for oil changes too, so I don't have to pull off the bottom engine cover.
You can actually pick up an oil extractor (works fine for this as well) from harbor freight for pretty cheap. Great for emptying out gearboxes as well. Won't get everything but it beats dumping a gallon (or 2 in some cases) of ATF all over your garage floor. Personally I just use my shop's flush machine in dipstick mode. Makes refilling it a lot easier as well.
Smart ! Ima do that .
@@rayspickler5247 Dang that's cool
I do the same thing & do it for changing the fluid 1x per year...
If it's on original fluids..the rear diff is going to be Whale Oil..that stuff smells horrible
That truck was one model year away from getting DEXRON(B) which also had sperm whale oil!
@no candy Am I the only one who thinks old diff fluid smells exactly like sweaty gym socks?
Fire up some Ramen and sip a survival water and let the Wizard make you feel alive again for the next 17:41. .
"A tisket, a tasket, The Wizard replaces the gasket".
Nice.
Yes! This is why I subscribe - watching the wizard perform his magic with his tools. The nice cars are good, the tool reviews helpful, but lots of people do that. Skilled repair and maintenance is what differentiates this channel. "Bob Ross with a wrench" is where this channel shines.
Well put, "Bob Ross with a wrench"
Pan gaskets I use have smaller holes every so often that hold the bolts in place so the gasket stays in place while installing.
i have also had the same experience. Diesel mechanic, but i also do side work on regular cars. But i guess maybe on exotic cars it might be a problem? Wouldn't know myself, I usually work on American, Asian and some German cars. Also, i always try to look for the torque specs and usually unless stated, go around the clock, ex 12 then 6, 1 then 7, etc. for the final torque
My thoughts as well on the dozens I have done.
I have owned over 100 cars and probably have had my hands in 200ish automatic transmissions and it just depends on the gasket company. For example the rubberish fram gaskets grab the bolt thread but the cork fram generally do not. Those awesome blue gaskets that I believe are made from silicone I have seen go both ways. It really just depends on the manufacturer. Since I have moved ro buying stuff from rock auto mainly I have came across all sorts of brands and some are real high quality and others are not and price doesn't seem to necessarily reflect the quality.
he studied in the amy ,he was misinformed .and never cought on
Mr. and Mrs. Wizard, you're the best!
Wizard, please do more of these instructional vids!
TH350s can be tough to seal..many times previous owners have overtightened the pan, warping the pan holes..sometimes the leak can actually be elsewhere above the pan and only appear to be the pan leaking.
Some torque converters on older vehicles had a drain plug so you could drain more of the transmission fluid out. Also, storing the super glue container in a refrigerator will prevent the glue from hardening.
Rob Stephens i may get that glue on my next hotdog the way my wife cooks,last time i put a bearing in the fridge to shrink it , it was near the stuff lined up to be thrown out. It ended in the trash .
That truck is beautiful. Love these old squares
Thanks for doing the extra video Car Wizard, I’m a massive fan from over the pond in the UK. 👍
Why super glue? My dad was a mechanic most his life and he taught me the 3M weatherstrip adhesive trick. Of course back then there was no super glue. Great video, and thanks!
Super glue was invented in 1942
ATF used to contain whale oil, and 1972-73 was right at the tail end its use in automotive applications. If it's the original fluid, that smell very well might be whale oil and other additives breaking down.
Fortunately they discovered jojoba oil was a superior substitute.

My personal experience with those rubber gaskets is that they are way more expensive than cork, last maybe a little longer, then begin leaking, and they stick to the surface like hell.
Went back to cork, no problems ever since.
Might as well say "fuckit" and just use a bead of black RTV sealant, like an oil pan, really.
Thanks Caprifreak - I'm about to flush my E40D transmission and decided to use a cork gasket. I noticed that there is NO ATV or other sealants used! Just the cork and a small sealant to keep the bolt holes in place.
Any advice? 10-12 foot pounds on tightening the pan. Seems real light.
anything with a pan...how about a pandemic?
That's funny. I felt like I was being a janky amateur when I got frustrated with the gasket slipping all the time and I carefully put a tiny drop of superglue on each outside corner, using a magnifying glass to make sure it was only touching the outside surfaces. Then I see the Wizard going completely HAM with it. OK then.
I've been using RTV for years to do that. Never thought of trying superglue.
The next guy to do yours won't have much issue.
The next guy to reseal the Wizards is going to spend an hour cleaning superglue and gasket off the pan.
Thanks for keeping us entertained, Weeeeeeeeeeeeezerd ! :-) I have been watching your channel a lot lately and am now a subscriber. Quality content as always.
Wizard, for years I used to use 3M weatherstrip adhesive to hold my pan gaskets in place. I didn’t have to use much and I could get it off pretty easy with a Scotch Brite disc even when it’s been dried for years. Just a thought if your ever out of super glue. Thanks for the video. It brought back a lot of memories!
Never thought to use super glue on a gasket. Thanks for the tip.
I use a dab on tiny screws when repairing computers. Keeps the screw on the screwdriver when you have to reach down in to put in the screw.
@@DarthVader1977 That's what magnetized screwdrivers and bits are for.
@@LN997-i8x I guess you've never seen a plastic screw.
Great video, could you talk about how often to change the oil for transmission, breaks, anti-freeze etc. The car I have now says never to change the antifreeze, what are your thoughts?
Good job on this video Wee-zard! I have a question about your method and the type of gasket you used. That looks like one of the thinner, paper-y type gaskets. I could see the Super Glue method working very well for that. But what about the thicker, silicone type gaskets. Does it work well at temporarily placing those too?
Timmy MacGruber you should always check what the gasket manufacturer says but a stiff gasket with silicone on the outside generally you don’t glue them or a thin layer of silicone. You want to glue gaskets to the part that come off so it’s easier to remove the next time.
Although I understand the Wizard has enough experience to feel how much torque to apply to the pan bolts.
Does he recommend utilizing a torque spec for those less experienced ?
flyonbyya look it up in a repair manual gonna be different . It’s easy to strip aluminum and crush cork gaskets , so if you don’t do it often check the torque spec. Most mechanics aren’t gonna torque pan bolts. You get a feel for it after a while.
Try to go by torque specs
It's usaully 10 inch pounds not ft pounds
I'd recommend starting off with torque specs if you're less adept with wrenching. After a while you'll be able to feel when the torque is right and when the bolt is getting too tight that you're about to strip aluminum or magnesium. They're very easy metals to strip so I'd be very careful working around them! If you're take a bolt off and it feels very tight, stop. Get a torch and heat it up or hammer the socket while it's on the bolt, you'd be surprised at how easily things come out after heat or a little vibration gets those threads loose. That was a very expensive lesson learned lmao.
On that transmission I would probably just tighten by feel also especially with a rubber gasket.
I wanted to see you add the fluid and start her up and all that good stuff
Thanks Wiz, interesting and valuable content so keep up the good work.
What are you doing to prevent coronavirus in your shop
sniffing trans fluid & super glue and washing wands with brake cleaner over spray... weren't you watching?
What’s it like for the next guy trying to get the super glued gasket off?
I'm also generally "the next guy" so that's why I use Gasgacinch
My first car was a 1973 Chrevrolet Malibu with a 350 mated to a 350 Turbo Hydramatic transmission (bitchin' name, good job GM marketing!) It was my grandmother's car, and when I bought it from her in 1985 for the token amount of $200, it had all of 48K miles on it. However, it had been parked outside in Texas for years, the paint was faded the vinyl top was cracked and the seats and plastic fantastic interior was all cracked faded and rotten. GM quality for ya right there.
Anyhoo - funny thing about the 350 Turbo transmissions from that generation: They had a design flaw and the 2nd gear band tends to strip out around 60K miles. When that happens you lose 2nd gear and the car then shifts from low to high: Your 3 speed is now a 2 speed.
Coincidentally, I had a B&M shift kit I had been meaning to install on the car but it was way too intimidating a job for a 16 year old kid to do in the driveway. Had I installed it and then the design flaw had reared its ugly head I would be telling everyone to this day all about how a B&M shift kit will destroy your transmission.
As it was, I got it repaired and had the transmission shop install the kit for me. I had them set the full throttle shift for 5K RPM (as it had been from the factory.) The car would scratch the tires going into 2nd. Fun times.
I’ve did the same super glue trick for other things as well
Best trick !
Question: What do you do with your rags? Trash them? Wash them? How? Thanks for the videos.
If it's like the dealership I used to work at There's a uniform cleaning service(think Cintas, G&K or amarak) that comes in once or twice a week and they take all the used rags to get cleaned and drop off some freshly cleaned ones along with your uniforms. I always had to run around and grab the used rag bins and toss them in the collection bag for them to grab lol
I use dental floss through the bolt holes, start all the bolts, snip the floss off then finish up. You can leave the floss but it looks stupid lol.
Hey wizard, have you ever encountered any problems after changing fluid on a transmission containing old fluid? I have heard lots of different opinions on this. Some RUclipsrs recommend not changing it, if you don't know when it was last changed.
Lovely video, Wizard. You have a very soothing voice.
Can you retrofit a magnet in the pan? Would it be worth bothering?
Hardly a "retrofit" 😂 and it would be a good idea
i prefer this Chevy to any new car.
I remember those trucks. They rusted faster than a Chevy Vega.
I have a '78 square body that's not rusty in south Texas. The road salt is the culprit
Thank you for posting additional videos while we're all at home!
Ya know, for running a shop and making money off people that don't know what they are doing, the wizard gives excellent advice for those that very well could be going to a shop to have something done that is so simple. Thank you wizard for being a good honest mechanic. They seem to be few and far between now
Wizard bless you for the public service you are doing. I have enough food supplies especially a Costco hubcap size cinnamon lattice Apple pie, 3 containers of ice cream and now more of your videos yeah!!🤗
Dishwasher = parts washer if you aren't married.
The bolt holes in the gasket are designed slightly smaller than the bolt diameter so you can use the bolts as alignment pins to hold the gasket in place with no adhesives never use sealants on trans pans the sealant can over time break off a small piece on the inside and get jammed up in the valve body I learned this back in auto mechanic trade school.
Hi man...can you put some light when you work....👏👏👏👏👏👏👏
A trick I use on the Pan gasket, is to use a steam iron, you use for your clothes, the hot steam iron, using steam will flatten the gasket perfectly, then it's very easy to hold it in place, and your not contaminating the gasket.
But for a newbie, a torque wrench is the best way to teach them how tight "just enough" should be.
Good to change the dipstick seal also
Whats wrong with the tacky gasket glue?
Some remarks: removing the Gasket should be done in moves parallel to the pan edges with Sanding paper. There is always the danger that oil is leaking because of scratches connecting the inner edge with the outer. ALso, if you overtighten the Pan it happens that the pan is disformed. The screw will bulge in the sealing surface and afterwards you´ll have leakes between the mounting holes.
Otherwise: good explanation, well done.
crud from around the transmission can fall onto the gasket when lifting the pan in place too..
Thank you SO MUCH for the extra videos, Mr. Wizard! This will make the quarantine so much more bearable. THANKS!!!
I thought this dude was about to hold the pan up to the camera for a sniff.
For the gasket I always used weatherstrip adhesive. Works great
Another good trick to hold the gasket in place is zip ties!
Also use a plastic or wooden scraper if removing residue from an aluminium pan, it's too easy to score an aluminium pan with a steel scraper. The last transmission service I did (on a ZF6hp26) the new filter came with a beautiful steel and rubber compound pan gasket that sat totally flat, it was brilliant. Please wear gloves Wizard! All those petrochemicals soaking into your skin, it's all increasing your cancer risk a little every time.
The brake cleaner on the hands was very scary for me. Nitrile gloves are a good tool.
Sewing thread tying the gasket to the pan in a few places. No adhesives are required. Makes it a lot easier for the next guy.
Nice trick on the gasket.
Thanks for the video, Wizzard. Do you have to drain the torque converter?
I love the period correct bug deflector
Yup they dont make em like that still wish I could find one for my 77 contintental.
I want to see another mechanic Hoovie episode. You could title those "What not to do" or "Don't let this happen to you."
That truck is screaming to me for some white walls
I gave this five stars despite using a different technique. If you are installing an old Brit or American cork gasket, I would recommend using Hylomar on the pan side and Loctite 515 or 518 on the motor side of the gasket. The super glue works for him and I have never tried that. My method seals some pretty crude cork gaskets, and when you pull the gasket off, the Loctite stays with the gasket. Priceless. This is also the old school high dollar method used on older aircraft. If you are installing a rubber gasket maybe his way works better.
Not related but I’ve changed gear box on 83 f150 twice w/rebuilt motor craft.Has new power steering pump and new lines. Looks like it’s combining out the bottom of gear box.
Thanks! Love your videos.
Good vid, Mr. Wizard :) A 2003, Toyota Camry, with U 241, auto trans, is similar, inasmuch? Just wondered, if the shift solenoids could be removed, for cleaning/ checking/ replacement, with the valve body, in-situ?
Mr WIZARD. Replacing the gasket and super glue...........perfect idea.
Changing the automatic transmission fluid.............total disaster.......that what most mechanics do and auto transmissions fail.
You left about 50 % old ATF fluid in the transmission (converter) and you charge the customer full price for servicing his or her transmission.
You just show me how not to change the ATF fluid. Can you show how to do it?
If one of my workers would do ATF change your way......it would be his or her last day at work (every worker have one to one training)
I know......this movie was about ......gaskets installation tricks only.
Have a good time mate.
Andy from Australia
SuperGlue?!? How 'bout....Permatex 80062 High Tack Gasket Sealant, instead?
*works great for valve covers, differential covers etc. too!
Absolutely DO NOT USE SUPERGLUE. it will make the rubber super brittle and break the seal. Making a leak. Use weather strip adhesive just to hold the gasket in place on the pan. Put bolts on the pan with the gasket on to make sure everything lines up. Leave in the sun but 10 mins. Helps rubber. After that. Its all about turning wrenches.
Nice video other than it teaches incorrect torque of the pan bolts which is a bad practice. It's overcomplicated because they were not installed correctly. There is a correct specific torque spec & procedures (Check your application for procedures and requirements before torquing to prevent warping etc.). People will almost never (maybe some can get them close by hand) But guess work or feel is never really ok on engines/trans. bolts etc. Just as you should never hammer on a harmonic balancer, you should torque pan bolts to spec. after checking the parts inspection procedures. The correct specs are there for a reason. And to generally teach people to just do it by feel is incorrect. Example, many people will tell you it's ok on a sbc (say a 350) to have the distributor startup cylinder to something other than #1 (say.. #2), that it does not matter. But if you don't follow the cam firing sequence you can easily have up to 3 cly's firing on each side of the engine before cross over, causing the engine to fire almost one complete side then switch and fire the other side. There are several issues this can cause on a normal street engine.
I would recommend educating people to follow procedures and specifications. Mechanics (in general) in many shops already have enough poor quality issues. Trial and error until you find out what is wrong is another example. They just start replacing parts until they happen to fix it without really finding out what really caused the failure. Please do it right. You're a pro, You can do it right. Reinforcing bad habits doesn't help anyone, when a new person does this for the first time and tears up something. Also, you should NEVER hammer the timing gear on the crankshaft as it can cause micro stress in the metal causing premature failure of the timing gear (I've been told many times, Oh, just use a 2x4 and hammer it on). Just another example of following the rules. To this day, people don't put thread locker on head bolts, dont torque head bolts, and use old head bolts. Over tighten them, use larger springs on a leaking exhaust valves.. And then wonder why they droped a valve! It's on and on... Just follow the specs, and teach others to do so.
I've heard it said by most that if a automatic transmission hasn't had regular filter and fluid changes best to leave it alone. Otherwise all the accumulated particles that were keeping the clutch together are now gone and it'll start slipping
And here this transmission hasn't been changed for 50 years?
Just curious about the longitivity of this transmission after the fluid filter change
I have a friend with a Kia that hasn't changed her fluid in 100,000 miles and no garage wants to touch it now
I know this is a bit off topic but, about that old Chevy pickup. Does that rear bumper wrap around the back wheel wells/fenders? My 66 gmc custom has some kind of ridiculously heavy duty bumper that apparently came from Plano Implement Company in Texas. Sort of a steel diamond plate.
There are going to be a LOT of pissed off people when they have to pull what ever gasket was super glued on. This is NOT a good idea. There are better options people....think! I know, I will have a lot of people thumbs down my comment, but really guys, DON'T do this!
Isn't the "black paste" (Motorsil ) better than the superglue? I hate that superglue stuff, it's rigid, dangerous if it goes on the fingers, it crystalize...
How is it that this living legend and Saint of a man doesn't have 1m subs, yet living pieces of trash like logan paul have 10s of millions... peoples priorities be effed up... your the best, car wizard!
WIZARD why no nitrate gloves? Used motor oil is indicated in cancer development. Maybe liquid glove? Pressman for many years, used liquid glove, lets you "feel" the parts without the nasties being absorbed
Will replacing the trsnsmission oil in this '72' cause the transmission to seize up and fail, even though it just a transmission Drain? I have a Mazda 5 2008 and transmission oil pan is severely rusted and the mechanic wants to replace it. I don't know when or if transmission oil had ever been changed (drained). Is it safe to do? Thanks.
Pan baskets are designed to hold the pan bolts for installation
The bug issue I run into is the two bolts behind the crossmember on my 69 c10. I raised the trans with the method above but unfortunately I don’t have enough clearance still to get a 1/2 socket, socket with elbow adjustment or a bent open end wrench. Any advice for these 2 bolts?
Don't understand why you are always making it sound like other mechanics are stupid except for you. They can't install a simple pan gasket? Give me a break! Back to South Main Auto for some real mechanical and troubleshooting videos.
When you drain the fluid out you might get a gallon or a gallon and a quart which could leave up to two gallons or so of the old "70s" fluid in the transmission. What I would do on this vehicle is to replace the pan with one with a drain plug. Then every week for about four weeks or so, get under it and drain it and replace the fluid with the same amount that comes out. If you do this for about six weeks, the old fluid will mix with the new and eventually get expelled from the system. Then if it's really old like from the 60s, 70's or 80s, get one of those filters with the magnet inside and attach it to the return side coming from the radiator, otherwise you've changed the filter, and replaced the gasket, but most of the old rotten stinky fluid is still in the vehicle. Some cars have a provision for draining the torque converter and if you really want to service the vehicle well you can do that. Otherwise a good informative video and a good super glue trick. I'm going to go get some glue for myself and go do the service on my 84 GMC sbc van , BTW, if you're doing this at home, Go to Lowes and get the concrete mixing pan for $6.88. It'll make cleanup a breeze.... Just sayin' MIke
Thanks for the video. Beautiful truck. Considering restoring one from the farm graveyard. Has a broken parking pawl and it’s rusted through in many spots.
I was most surprised that the 3/4 ton had a 350/350. My '79 is a Camper Special with a 454/400, though I wish I had the economy of the smallblock.
No gloves, Wizard? Prolonged contact with oil/ATF is a known carcinogen. Also causes contact dermatitis which is not fun! Don't want you to have to retire early due to health issues. How would i get my Wizard videos from then???
I can't bear to watch, Dave works on so much of Tyler's shit boxes and foreign shit I don't feel he deserves to work on a real Chevy.
That truck is going to need all new rubber brake lines ,4 shocks , full tune-up all wheel seals and importantly that main carrier bearing is going to blow sometime soon.
Is it a 2 barrel or 4 barrel? 26k it has a new stater and master cylinder.
And Dave back 100 years ago we only had Permatex Indian Head sealer and Permatex spray tack red and cork or paper gaskets.
Years ago it was Indian Head on the pan side and grease to soften the cork on the other side.
What about the rest seal and the filler tube oring?
Awesome video! I am bored no longer - however:
Transdermal ingestion of solvents and dirty oil is a real thing; I’m thinking some PPE for your hands would be a wise choice, and safety side shields for your glasses when working above your head would diminish further any chance of errant materials or fluids getting into your eyes.
Stay safe, Weezard!
How as this Truck kept in such good condition? Was it kept in a barn or garage? I am curious to know how the owner took care of it before Bob found it!
I agree, where did this truck stay and for how long to be in this condition?
@@stephenpickard5178 watch the video before this..
Check out Wizards previous video on my truck. I posted the story at the top of the comments.
Ehhh normally I'm with you on your wizardry, but I'm gonna have to disagree with you on this one. If you're gonna use something to tack a gasket in place I'd sooner use RTV or maybe gasgasinch. I realize neither of these are good for transmission fluid applications but neither is superglue...
Preference: cork or rubber?
I tapped mine around and where it was leaking. It stopped after tapping it with a screw driver and hammer. Then I torqued in between the bolts where I stopped the leak again. Haven't had a leak since.
Just bought a 76 C20. Same tranny as the video and mine is leaking pretty good. Pulled off the pan and it was a newer gasket so I’m guessing the guy I bought it from replaced it. The 2 bolts at the rear where the cross member is aren’t original like the other 11 bolts and those holes are cross threaded.
Great teaching video. I didn’t catch if the truck is a daily driver and how many miles on it. What do you think about people saying don’t change the trans fluid on an old vehicle with over 100,000+ if it’s never been serviced and is working fine?
I've ridden crouch rockets since the 80s that's exactly how you torque on them, no leverage or your pulling out threads. Also clean threads with carb cleaner before assembly.
Whats a good ATF to use on an old th350 tranny?...the oil section at the store these days is crazy with all the new oils...wondering the same question on my engine oil...i have a 69 impala all original 350/350...and just need a pointer on what oils to use on both my engine and tranny.
I was told by the oldschoolers to never use glue and rather use a small bead of the correct RTV to smother gasket for sticking. I suppose the reasoning was that glue can crack where trans RTV remains pliable.
Thanks man. Been lurking and watching so now ya have a new subscriber. I like yer style and straitforwardness. (Is that really a word?)... anyway. Keep doin these good vids.
Great job Mr. and Mrs. Wizard ..... I think you might have to help John Ross from WatchJRGo a hand with his Ranger.....thing just does not want to stay running!
Wonder why old transmission fluid from that era had a distinct smell? Once upon a time whale oil was, in fact, used in transmission fluid in the US. However, it was finally banned. Then Automatic transmissions immediately began failing all over.
I'm not a mechanic, but I play one in my driveway. I would probably soak the pan in acetone to remove the old gasket . Acetone removes almost anything , and leaves it squeaky clean, without having to grind on it. May cause cancer though
I wire wheel it off and shoot it with some paint what the gasket doesn't touch. Also I like to add in the seal the TV cable and selector shaft. Save money in the long run for a few extra minutes of work.
I guess you'd expect the gasket to be shot and leaking a bit. Assuming that u weren't having shifting issues, why "open a can of worms" and disturb a transmission that's lasted since '73?
