tcc problems

[carter442]

ok guys so i have a 95 beretta 3100 4t60e randomly i would lose lockup along with random gears. usually i would let it set for a minute or let it set over night for lockup and it would start working again. now i have no lockup at all and no check engine light. is this a common problem with these? my first thought was the clutch but if there is a common problem i would like to know first, any help would be appreciated

it happens, i think more usually in the 93 and older cars. many just unplug the sensor, and replace it when they get a chance. it will effect gas mileage, but i'm not sure what else.

Only on the TCC is that common(and really that was for the 3T40 as said). As for the gears by far no. Sounds like the switches on the valve body are going bad or the ECM is going out. Or you have a short somewhere.

i ran a truck like this forever but the tranny did not like it found that out with a temp gauge. now im not familiar with these but do you have to drop the pan to replace the solenoid?

Hold off for better info before you do anything. I just took a guess.
If the switches are the problem you will have to take off the side "pan"(cover).
The 4T60e trans god here is 3X00.

i wont pull the trigger on this before i am sure. do these cars have trouble codes for the tranny in them? i know they are obd1.5 but obd1 had atleast a tcc code so i would hope these had some code.

didnt even realize you had posted i was replying to the first post and must have posted right as you did sorry about that

Man not sure on the codes. On review I saw that you once had brown fluid, that is something I have never heard of. Now I'm thinking there is a bigger problem. I've had orange fluid in a 700r4 that was slipping.

Hey no problem.

[carter442]

brown fluid as in tranny fluid? i didnt mention that was that on another post from a long time ago? and my fluid has always been dirty not gonna change it since it most likely hasnt been changed so alot of the clutch material is probably in the fluid. if it will throw trouble codes most likely there would be one for a short. with it being so intermittent as far as the gears i would not think those are shorts my thought would be shift solenoids and tcc solenoid. reasoning is 90 percent of the time it works and just started the tcc problem recently and no codes to indicate a circuit problem

[Money pit Beretta]

Yeah that was back in May 30 2011. Dude you have to change the fluid, filter and clean all the metal(flakes) off the pan. Really it may be too late, but it is worth a try. A new or rebuilt trans costs alot.

[Money pit Beretta]

Oh if you need a spare I have one that worked when it was taken out. Not sure if it still does, but if you are not too far away I'd let it go for shipping. It needs to be rebuilt, but shifted just fine with an adjustable vac modulator.

when i was in school and had automatics class pretty much we were told if you have never changed it dont worry cause all the friction material on your clutches is in you fluid. iv actually only had one car that had red tranny fluid even after a change

[Money pit Beretta]

I never heard that in school. That was a long time ago though. You have to change that stuff from what I've heard and learned along the way. I've had dark fluild and it has always had a red color still. Well that may be just a red tint, but still.

[carter442]

that is what our instructor told us now the thing is how many miles does that hold for i dont know. he told us he has seen many problems where people would change their fluid and then have random gears go come to find out not friction material was on the clutches. now that being said i did not get much out of that class and he could have been full of it but it was not the first time i heard that. we basically tore trannies apart assembled the gear sets and learned how each gear was achieved. we did very little with diagnosing problems like this.
