- A friend of a friend who makes him my friend now bought a Supposedly Built Ford C4 Transmission... while he got a decent deal on it... was a complete let down! it is plagued with problems and so I turned to the C4 Transmission expert Harold Miller of Dynamic Racing Transmissions 203-315-0138 and explained what Michael is going to do with the car and what we are working with. I am sending him the hard parts so he can work his magic on it and in a part 2 you will get the complete assembly video!

Thanks Andy for the props!
We try our best at Dynamic to get the customer what they need.
We are a family operation with just three employees, but we work like a team of 20!
I have a 68 Mustang with a stroker 414 with c4 on the back of it. My brother-in-law is a transmission specialists and I watched him build mine which has hardened shafts all the clutches are Kevlar. I have a P/A salvo of P/A 6th gear planetary gear system And built me a real nice valvebody With a 3200 RPM torque converter. I have had absolutely no problems with it at all. Considering I bought a transmission through summit which was a TCI built transmission I did 2 runs and burnt 1st and 2nd gear out of it. TCI said don't do anything to it send it back here to Mississippi but I had to pay the shipping costs. So my brother-in-law and I took it apart everything in that transmission said Fomoco, all stock components. It's nice to have someone that you would know build you a high performance transmission and knowing what they're doing.
You are not the first guy that paid big bucks For a TCI C4 full of Ford Stock parts. I also got caught in that one! All the Transmission shops I talked to said a C4 is no good put a glide or a turbo 400 in your car. The glide doesn't have enough Gears for a Small block Ford, the other eats horsepower. My Broader C4 is as good as any C4 built It will handle 1000 hp.
@@mylanmiller9656 The mine is rated for 750 horsepower And that's more than enough nothing wrong with overbuilding.
I ran a speed shop back in the 70's and 80's. Another garage brought me a turbo 400 to rebuild. After I rebuilt it, they took it to their shop and installed it. After the install they test drove it and called to tell me it was working great. A few days later they called to tell me the trans had failed. I had them take it out and bring it back so I could make it right. When I took it apart, I found that it was full of debris. The other shop never flushed the trans cooler, lines, or converter, and all that crap totally plugged the trans.
And stuff like that is why alot of shops won't bench-build a transmission.
@@jeffduncan9140 the place I worked at would do them ,but only if you installed a new cooler (or anything else that the trans fluid runs thru).
Can't prove you got a new cooler or replaced your rad with internal cooler and you want a rebuild ,well you're gonna buy a cooler/new rad from us or we won't rebuild it.
@@MrTheHillfolk I'd be good with that deal.
I burned up the forward pack when I did not get the converter in far enough to turn the pump once. On a freshly "built" one, hard lesson learned.
No matter what the seller tells you about a transmission, just consider it a rebuildable core.
🤪😎Thank you Andy once again 🙏.
I've had a Mighty Mite C4 from Dynamic for 20 years now. Absolutely love it. Agree they have great customer service too.
Buy a C 4 Ford from Broader performance and you will never Complain.
Mylan, I have dealt with Broader Performance in the past and have used their parts which are good... but to me Dynamic is the best because Harold (aka Jr.) Is the difference! He has always taken my calls and answered my texts and has never steered me wrong!
So many different transmission people anymore, I guess it could be a good thing or a bad thing. More competition supposed to be better but in some cases you end up with three things. Best , good and mediocre at best. Nice to know.
I dont think I bought any used Transmission for more than 100$. I flat out tell them unless the pan is off and I can inspect its not worth it. They usually sell it for under 75$ and wouldn't you know its never been apart. 🚒 Good stuff Andy thank you.
I've always liked the c4 in the ford dirt cars I ran back in the day. They didn't rob as much power as the c6 and worked just fine stock in the class I was running in.
They are good transmissions for what they are! The one in Casper it built as much as one can build them.. it's getting ready to get torture tested.lol
@@UnityMotorSportsGarage looking forward to seeing it
Had an AMC 727 made by Mopar. Bought a reputable reverse valve body and rebuild/bulletproofing kit and did it myself. Held up to 900 HP for years.
One thing to keep in mind with the fluid check is anyone can drain the bad fluid and refill it with fresh fluid so be Leary if they push how nice the fluid is and listen to your gut feeling about them
Buying a used racing transmission what could probably go wrong .. I learned a few lessons on used even a used Harley . Enjoy your videos. The only thing I can suggest is knowing where to go if it does not work out. Thanks for the videos
I'm a transmission builder and I won't buy an unknown unit unless it's cheap.
witness marks on the bolts are always a tell tale for sure !
Thanks Andy, your absolutely correct about buying used transmission and converters.
I have seen people go through this many times.
The mods and rebuild on the C4 look great.
Thanks for sharing.
Take care, Ed.
Thanks Ed!
Looks like a nice core to me! Market place everything is “rebuilt “ 😂
Sometimes you get a good deal , build to fit power train . I built a C6 years back changed 1-2 planetary gears so I could leave faster with street gears R valve , Lincoln front drum for more clutches, deeper pan .. know the right people with the Best know how.
Using Used Torque Converters..... ug. That's like putting a Junkyard Fuel Pump in there, and worse.
I have a couple transmission for sale, and they all have Torque Converters in them.... and I tell everyone, that they are only in there to plug the hole & keep dirt out of them. Like you said, just don't risk it. A clutch I can inspect and put it back in there if it's in good shape.... a TC, I can't, and pulling a transmission is one of my least favorite things to do.
Good information Andy just had a situation recently where my cousin went through this and I told him the same thing you just said about using the converter when your unsure of it and you probably saved someone alot of heart ache with this video thanks for your knowledge and sharing this
Thanks Terry! I've been through the school of hard knocks..lol thanks for watching
Andy
One mistake many rebuilders do is to use way to short screws on the servo-cover. This will make the C4 take a bleeding "suicide" as soon as the servo gets activated
buying a "used" "built" trans is a high-risk gamble for sure, let me guess, it was rebuilt and mocked up, never ran, just decided to go in a different direction type of deal!
That pretty much sums it up!
Dynamic Race Transmissions always held up good in my Brothers Foxbody, Built Up Fully Rollerized, With Rev.Man. Valvebody, C-6. Buddy off mine ran a Migthy Mite C-4, in his Foxbody, was going Mid 8,s with No Issues Whatsoever. Dynamic was pretty much the innovators of Building up a C-4 that can take some serious abuse. I used to run a Proformance Pro C-4 in my Foxbody, No Issues with there's, Besides a Leaking Issue, which Actually Harold Sr. Fixed For me in Branford, at the Shop. It was always nice living pretty close to them all these years. I know they built really Good C-4,s and C-6,s Years Ago, and I'm sure they still do.
Since he got a good deal on it your friend did not get ripped off... It's hard when people don't know who did what to the object... When it comes to transmission if used & out of the car I assume it needs rebuilt... I got really lucky on a th 400 with a Pontiac bell housing. The others I knew or assumed they needed rebuilt... That can burn you as well
I build all my own stuff and assume that the one im buying is only a core until I know different. If they won't allow you to remove the pan they are not worth buying. Converters need to be replaced or gone through just about every rebuild unless you know no trash has made its way through it. When the seller realizes that you know your stuff they get weary of selling you the bs
You can send that total converter to TCI and other companies will go through it and it is cheaper than buying a brand new one
great content
Thanks!
I was going to say you are supposed to be buying a Lenco for Casper not a spare c4 to kill. 😂
No if I kill the C4... It's time to move on! 😆
Very good and informative video on how to tell what it is what you are looking for and / or at. That could be beat to death and or have over 50K on it. Like the information on the letters on the servo's! Enjoy your evening and we enjoyed your video as always. Great information as always! 😉
Thanks John!
Andy
@@UnityMotorSportsGarage always welcome. John!
Good video Andy. Very good points about torque converters. I never reuse old converters unless they have not been run since a rebuild. Regards Greg
Thanks for watching Greg! I seen your question last night on Clevelands.. I have a set of D3 Yates heads that we plan on using on a build in the future...
Andy
@@UnityMotorSportsGarage always a pleasure to watch your channel and DV's. Personally I'd like to thank you for the help that you provide to DV. I realise that he is a special friend of yours, but without your assistance, we, the viewers, wouldn't be as privileged as we are with his videos. Looking forward to your D3 head project. If time permits, and it falls within the scope of your project, I would appreciate some comparison thoughts on both the 2v and 4v heads as made by Ford, relative to the D3's. I currently have 3 different Ford motors in early build. A 347 windsor with GT40P heads, and EEC V injection, a 393 Cleveland with Australian 2v closed chamber heads that will have a fabricated manifold and custom EEC V based injection, and a 408 Cleveland with 4v closed chamber iron heads with a single plane, and a Holley.
Cheap is expensive!
The poor man pays twice! Some times you get lucky with cheap or second hand parts, but sometimes it cost you double as you have to buy another (pay twice)
Bummer! Used transmissions are like a box of chocolates….You never know what you’re going to get!
Hey Andy, sorry for the off topic comment but, I tried to ask them on the Live the other night but too busy I guess. Anyway, what I wanted to inquire about was…
SBM valves open near the centerline of the bore, less valve shrouding with the smallish 3.91 bore.
The spark plug is more centrally located in the chamber (for a wedge) than other makes.
Tony mentioned the ‘one year only’ Rochester 2bbl with more CFM than the Carter, but not using it now?
I'm a engine guy but I'm definitely not a transmission guy . I completely suck at working on automatic transmissions
Yeah I'm a Engine guy also... I know enough about transmissions to be dangerous! Lol
Andy
Do you know that Florida Gators love the taste of people that said they did something and didn't.
🔔😎 YeeeeeHaaaaaw!!!!
Andy are you doing a video assembling the C4?
Yes when I get the hard parts back from Dynamic I'm going to do an assembly video.
Thanks for watching
Andy
Hello i have a 1971 ford f100 with 302 and fmx transmission the 302 has 4bbl carburetor and edelbrock intake stock headers from 87-93 mustang and 2 inch exhaust system my fmx won't shift into drive as soon as I start it has to run for about 5 minutes before it will go into drive but rev. Works great do you know what it could be thanks
Andrew, that is Called Morning Sickness in the Ford world. Basically the seals are hard aren't doing the job and once it has some heat in it the seals will swell and will apply the clutches in the trans.
Hate to say it but it needs a rebuild
Hope this helps
Andy
@UnityMotorSportsGarage thank you for responding I found a c4 out of a 79 that bird in the junk yard would that transmission fit in place without changing my drive shaft cause I had a custom 1 piece drive shaft made for the truck?
@andrewforster4974 does yours have a bolt on yoke or a slip yoke on the trans?
@@UnityMotorSportsGarage slip yoke
Is c4 transmission hard to find down there?
They are getting harder to find forsure.. but can still be found
Thanks for watching
Andy
@@UnityMotorSportsGarage If you know of anyone who needs any h servo for a street bulid I have three of them I took out of working transmissions that were being up graded.
I bought a c4 transmission fluid with pink as it could be everything look good until I got it home and pulled the pan off and it was black as smooth needless to say the man did not help me any at all took my money and run
I won't buy anything used anymore unless I buy it from a friend been burned to many times
You and me both!
Andy
Cant cheap out on a transmission
Harold is still building trannys? Wow
His son JR ( Harold) is..
Must've been "built" by tci. Warranty be dammed
There's gonna be a lot of these coming out now Someone is always scamming 😒.
I don't know about the videos... But I do know someone is always scamming unfortunately!
Andy
@@UnityMotorSportsGarage UTG has done two and now you've done one. Sadly this is needed.
Looks like it just came out of the junkyard
Personally I..blame squirrels
Personally I blame Ford 🤷
