tcc problems

[carter442]

and when i say brown i mean to look at it it looks brown but there is a red tint all my trannies have had red tint but the fluid has been dirty.

[Money pit Beretta]

Dirty is one thing. You have got to change that stuff. I understand what he said, but there can be alot more problems if you don't change it the long run. Ok if the clutches are that far gone it is too late anyway. Yes it will last longer, but it is still screwed.

[carter442]

this isnt a huge issue to me i would like to fix my tcc if it does need a new solenoid il have to get into the pan anyways. i havd made my money back on this car it was just for college for the most part

[Money pit Beretta]

Ok...guess it is to me. I'd like to see this car fixed and doing well, but I'm a Beretta fan that thinks that the more that are on the road the better.

[carter442]

dont get me wrong i do love it i normally get awsome highway fuel economy and its not in bad shape. but there are many problems with it technically it should have been totaled out. it got hit hard enough to deploy the air bag also my exes sisted backed into it and dented the drivers side fender pretty good i actually could not open the door. i personally am not a car person now i do like the looks of the higher optioned berettas like the gtus and z26s i would love to own one i am more of a truck person always have been always will

[Money pit Beretta]

Cool man I understand. Yeah it sounds like the poor thing has had a rough life. Carter I got to go man, good to see you back after almost two years.

[carter442]

thanks for the help hopefully i will get this figured out and il have lockup back. i hope it will make it as long as my cousins beretta same exact year he has lost 4th gear all togethor lost it about 200k now his beretta has 260k and he just gave it to his parents for them to drive.

[Money pit Beretta]

Your welcome, but I don't feel as if I have helped much. Wow... not sure how you cousin got away with going that long on three gears.
I hope 3X00 will jump in here and give you some real help.

[berettaboi]

yeah like has already been discussed, if your fluid is low(should have mentioned ---first thing to check actually), or getting pretty brown (it's a nice bright red when fresh), then it could go either way when you change the fluid. but it isnt meant to last forever

TCC issues on a 4t60e are not common, they use the same solenoid as the shift solenoids and they don't fail often at all. To replace them you would have to take the side cover off.

Unfortunately it sounds like you may have some other issues but the place to start is the pressure... I would try to rent or buy a trans pressure gauge and check that because if thats low it would point at the pump, if not then that would mean the valve body is starting to stick due to worn valves and such.

These transmissions do not handle mileage well and I can guarantee your reverse shell is on borrowed time as well as the 4th hub splines since those always strip out, but along with that the shift valves being aluminum with the valve body will wear quite a bit and actually sideload and begin to stick. I've swapped out all of mine for anodized anti stick valves to hopefully avoid this from ever happening.

There is no easy fix for this pretty much, so its probably best to start looking for a JY trans or rebuild this one if you know how to.

If your cousin lost 4th gear then he stripped the 4th gear clutch hub splines.

The thing that a lot of people don't like to hear is, the transmission is a wear item, it wears out... at mileage above 100k depending on service intervals you could be looking at needing a freshen, and there is nothing that fluid will help or changing a solenoid. Unfortunately the 95 transmissions also had some things improved upon as they came out with the newer years so there are those issues with the Valve body which will cause shifting issues as well as falling out of lockup and also the premature 4th hub failure and reverse drum.

Images of parts pulled from a 96 trans with 74k on it.

ya i understand where you are coming from. i know trannies wear this car got me through college i put 30k on it in less than two years if i have to replace the tranny i will prolly park it i only paid 800 for the car and a tranny is about 2 grand new and a junkyard one is a hale mary but thank you for your help. the random gear loss sounded like shift valves because i would rev higher then randomly drop into neutral. sounds like the valve was sticking then when it started moving it closed off both passages and dropped out of gear.

[3X00-Modified]

Thats shift flare and can be due to slow pump failure, or starving for fluid. when a shift valve sticks it will just not shift. I had that issue with one trans and it was due to the differential pin letting go and spreading aluminum in the fluid so everything just started to stick.

[carter442]

i will just see how it does like i said it is usually intermittent so maybe it will come out of it. my fluid is full checked it so i will wait and see.

[3X00-Modified]

Good luck, but all a transmission is; is a big hydraulic pump and when it doesn't pump those clutch packs don't hold or don't engage... So I can't see a fluid change fixing much of anything, or it just fixing itself.

[carter442]

thank you for your help i really appreciate it. i dont expect it to come out and work forever if it just makes it till my jeep is done i will be ok. to be honest it amazes me it has made it this long and i am happy it got me through college.
