I have a 4l60e but have a tcc cylanoids is stuck open , how can I get it to close and why would it do This . There’s a wiring issue some sort of ground short that could cause this I suppose, but don’t know why it would say tcc stuck Open. Man you the man I watch a lot so keep up good work
I recently found your channel and am trying to eat it all up! You are a transmission genius! Thanks so much for your knowledge! I recently rebuilt a 98 4L60E and could not get the servo out. I gave the transmission the rest of a TransGo shift kit but not any servo upgrades. The truck will not shift less than 6000 rpm’s now. Could this servo be lazy compared to the rest of the upgrades?
Update, we got the servo apart and made the changes accordingly. No difference. It doesn’t matter how we drive it, it revs up to the moon (6,000 rpms) before shifting. Any thoughts or ideas? Maybe I missed a check ball?
Grreat video...ive got tbe clip soaked in brake cleaner allready but i wanted to see a video before i tackled this...taking my eyeglass screwdrivers out with me and the wirebrush....i was gonna whack the cover a couple times with the rubber mallet too....if that dont work then the splitting maul should pop it free😁😁...DISCLAIMER...NO MAUL!!
I've got a 95 G20, and going to rebuild mine. Going with heavy duty clutches and it was recommended to use a Corvette servo? Also upgrading the sun gear to the stronger one other than stock? Anything else I should do to make this trans last longer?
I bought an 03 4wd Silverado recently. Near as I can tell it has a healthy 4L60E. I estimate it was rebuilt about 40k miles ago based on average miles of truck and a date code on the torque converter. I checked to see if it had a Corvette servo. It did not. I assume it is OE speck rebuild. I would like to maximize it's remaining lifespan. I plan on adding an auxiliary cooler. Do you have any "in the car" valve body improvement recommendations to maximize 4l60e longevity? Something like this ebay ad?: "4L60E 4L65E 1996-2006 1870 P1870 Code Buster Combo Kit Corvette Servo ATSG Book"
Thanks for the great series on the 4L60E. I'm starting my second pass on all the videos. Have you considered a diagnostic series for this xmission? It would really help those of us who are starting from scratch, especially if it tied the theory to the symptoms to the diagnosis. Speaking of diagnosis, I had to change the radiator in my 1996 GMC c1500 4.3. Everything was great for the first 400 miles. Then, in a matter of 3 or 4 miles, the transmission started slipping and then no motive power though the engine was running fine. Popped the hood and everything was drenched in transmission fluid. Needed to get it home where I could fix the line connection so I had fluid brought to me; added 2.5 quarts and made it another 4 miles. No power again. Added another 2-1/2 quarts and made it the last mile home. Went out the next morning, started the engine, warmed it up and checked fluid level and added 1/2 quart to bring it to full. Hopped in, put it into gear and ...Nothing! No gear, forward or reverse. Thoughts??
Thank you for the positive feedback on the 4L60E video series. Yes, I do plan on diving deeper into the diagnostics. The "Basic Operation" videos are laying the ground work for future diagnostics videos. We first gotta understand how a healthy system works, before we can recognize problem areas, and before we can understand (and hopefully appreciate) solutions that people/companies have developed. I'm sorry to hear that... Are your cooler lines held in place (at the radiator) with wire clips? Those retaining clips can wear out, and break. Note: If the cooler lines are able to bounce around, during driving, it accelerates the wear of those clips. Every time those clips are removed, they really should be replaced with brand news ones. When a cooler lines pop off, the trans will lose a lot of fluid, in short order. This kind of event almost always results in smoked clutches.
I'm going to add the video to your channel it's called servo on 2001 Silverado 4l60e it's kinda hard to see did my best though for the time I had trying to use the mirror and record with the phone just want to know if you think I will have enough space there to remove it and install my new servo? Thank you.
Can I use a steel wire brush it won't damage the bore will it? I love in Michigan my snap ring is rusted out it won't budge I need some advice this thing looks like it's gonna be a nightmare any help would be appreciated thank you.
Yes, you can use a wire brush to knock debris away from the servo cover and snap-ring. However, do not use the wire brush inside of the servo bore (underneath the servo cover). Scotch-Brite works good for the section of the bore that lives below (or inside of) the servo cover.
So do I just keep spraying and scrubbing the servo cover? It looks like it has become one with the cover so disappointing, living in Michigan is bad for rust I had to super heat my old O2 sensor with a map gas torch and spray it down for a week straight to get that out. Any more tips? The cover should not depress at all with the snap ring on should it?
That really sucks about the rust (O2 sensor, etc). We don't have that problem in AZ. I may not be the best help when it comes to a rusty snap ring... Can you shoot a short video of what you're dealing with, and post it on your channel? Then you can share the link/video on this comment thread. Note: If you can, get a close up of the snap ring opening/gap. There's two different kinds of snap-rings for the servo.
@@SouthpawAutoworks ok I will do that do I have to press in on the cover before I take out the snap ring?The cover hasn't moved yet but I haven't applied very much pressure to it yet gonna get out a big pry bar if I need to push it in first some videos don't show to push in the cover before snap ring removal? I'll send that video tomarow hopefully. I sprayed it down and scrubbed again with wire brush brake cleaner and atf mixed with acetone homemade penentating oil. Also have you ever heard of or experienced any problems getting the servo assembly out on 4wd ext cab Silverados mine is a 2001 looks like it will be pretty tight.
I did not realize that the trans was still in the vehicle. Might be hard to get a video of the servo, as it can be tight quarters. Missed one of your questions earlier: "The cover should not depress at all with the snap ring on should it?" Answer: It's normal to be able to push the servo cover inwards with the snap-ring still in place. 01 Silverado: It's normal to not have a lot of room when pulling/installing a servo with the trans still installed in the vehicle. IDK if you've already watched this video or not: ruclips.net/video/pcTBrf4GQh4/видео.html Note: 3 min into the video covers servo removal.
@@SouthpawAutoworks I think it will come out if I tap on the back of the screw driver now it's cleaned up alot since I started cleaning with wire brush I have one of those inspection mirrors with a light on it I see where the gap in the snap ring is now to it's right by the servo outside housing window too so that's good I'm just wondering if I'll be able to get it out and back in if worse comes to worse maybe take out trans mount and lower trans a bit? or do u think I'll be ok? Just worried I won't be able to get the new one back in how tight it looks. I'll send a video.
I like your idea (lowering the trans). I imagine that you'll gain some more room to work by lowering the trans, a little bit. If you decide to go that route, you gotta keep on eye on some stuff while lowering the trans. If the engine has a distributor on it, it'll come into contact with the firewall. Don't want to stress any electrical wires, cooler lines, etc. I'm about to watch your video.
3:01 not true. I’ve had those stuck so badthat no amount of beating, vice grips, WD 40, propane heat(NOT acetylene) will loosen the cover even a little bit.
Install a rebuild 4l60E in my 2002 Surburban . Shifting ok normal. Once its under Light Excelleration starts acting weird like it struggling to shift . at 55 MPH and I try to see if Passing gear was working . RPMS go up and doesnt pull. But once I have it on a slow excelleration it will pull up to 90-100 MPH no problem .. Could a new Servo fix this ? solenoid issue?
Hey bro! Please respond man I cant get a straight up answer from no where. Im really pretty familiar with these transmissions and a DIYer and ive installed many corvette servos and other things. If im getting a lazy 3-4 shift, does flipping the 4th gear servo piston help tighten the band??? I can add shift pressure through a tune but I will only do so if you say its safe.
I personally don’t have any experience flipping any components, within the 2-4 servo stack-up, for the sake of tightening up the band. The aftermarket offers different length servo pins, as well as shims. Some builders will make the servo pins longer, where need be, by adding more material, with a welder.
I had my servo cover blow off after 60ths that I have put on the vehicle. I was able to have all the parts saved by the heat shield. I reassembled it and while at it changed the filter and topped off fluid. It worked fine for about 2,000 miles and again blew off. I ensured the snap ring was in place. And for an extra put a collar that I had laying around between the center of the cover and the heat shield thinking that it would keep it from happening again. What would cause so much pressure on the servo to blow the cover. Transmission shifts fine. No slip. Any help would be awesome.
I'm a little confused by your first sentence... But, this has me thinking servo cover snap ring. If the snap ring isn't engaged all the way, the servo will pop out of the trans case. The snap ring groove (inside the trans case) must be cleaned out really good. Leftover debris, in the groove, will make it hard (or impossible) to fully seat the snap ring into the groove. Working on these things with the trans in the vehicle is a challenge. It's hard to see. Lack of lighting, bad angle, etc. When time permits, I'd like to make a video on this. Wishing you the best on your 4L60E. Note: I've seen a 4L60E transmission case get destroyed, by the 2-4 Servo snap ring not being seated all the way. Without going into anymore detail, I will say it's super important to make sure the snap ring gets installed all the way (seated).
@@SouthpawAutoworks thanks for info. I'm going to get a new snap ring and seal and go for it again. I've been lucky that it has always failed less than a block away from home saving the tranny.
Thanks a heap , however my problem trans. still installed ( 2007 Trailblazer ) not much room cat in the way too, any thoughts Thanks again ( I'll clean a third time ).
You could see about lowering the rear of the trans (removing the cross member)(make sure engine doesn't make contact with the firewall). Might have to remove exhaust, to get cat out of the way.
If I'm reading your comment correctly, it sounds like 3rd gear is slipping. What about 4th gear? Works fine, or is it slipping, too? Why was the trans rebuilt? For the same reason?
Is it slipping for a second, then up-shifts into 3rd gear? Does it slip when the engine/trans are cold? Does it slip when the engine/trans are up to operating temp? Or does it slip regardless of engine/trans temp? Why was the trans rebuilt? Failed 3-4 Clutch? Some other reason? Please specify.
I got the same problem with my transmission, it’ll hard shift from 1st to 2’nd but once in 2nd gear it’ll hit 2500rpm and it just flares and shoots up without even going to 3rd, so when I manually put it in 3rd it slips. I’m about to change the servo next week and solenoids will this help in any way with the problem ? Will it send it straight from 2nd to 3rd or is my transmission fried at this point?
I wouldn't think so... The 2-4 Band and 2-4 Servo are partially responsible for creating 2nd gear and 4th gear. If you're missing both 3rd and 4th, it's likely due to a failed 3-4 Clutch. Super common on the 4L60E.

Nice details on removing the servo cover off. Thank you for the quick video on it. Awesome job 👏 👍
Thank you brother! Your videos are helping me a lot - you are a great teacher, and I love your energy and enthusiasm!
Glad to Hera that you're getting value out of the videos.
Another thorough and great all around video. Your pointers help alot of folks, thanks brother.
Glad to help.
Appreciate the positive feedback.
Thanks for dropping me a line.
I have a 4l60e but have a tcc cylanoids is stuck open , how can I get it to close and why would it do
This . There’s a wiring issue some sort of ground short that could cause this I suppose, but don’t know why it would say tcc stuck
Open. Man you the man I watch a lot so keep up good work
Man! Took the cover with the 'O' ring out. That was hell!
It can be a major pain.
iv'e watched several videos on this topic, can't wait to install a corvette servo in my truck!!!!!
Right on!
Wishing you the best on your truck.

Hello there! I have a question, how long did your first rebuild take, compared to your last?
Is there a high performance servo I have a 1990 Chevy 1500 with a TBI and a 700r what's a great servo to get

@SouthpawAutoworks it slips shifting to third for a bit, yes 4 gear shifts fine,I rebuild it for burn 3-4 clutches,,

good Stuff
Merci.. Thank.
I have the 4l60e that only is going into 1st and 2nd gear will this have anything to do with it
I wouldn't think so...
The 2-4 Band and 2-4 Servo are partially responsible for creating 2nd gear and 4th gear.
If you're missing both 3rd and 4th, it's likely due to a failed 3-4 Clutch. Super common on the 4L60E.
No no no you just get some vice grips on that knob that sticking out and rotate it comes right out
