Transmission problems 94 A4
Lately, my transmission slams into gear really hard when the vette is first started. Tonight when I took it for a ride on the interstate, it would not shift into over drive. When you took your foot off the gas, it would shift into overdrive and the rpms would go all the way down to idle. Then when you gave it the gas again it would be in od and down sift as soon as i got to 1800 rpms. So the whole night i was crusing @2500rpms at 75mph. Also, when leaving from a dead stop it takes more throttle to get going; like the car lags from a dead stop.
I'm really worried because i just got a zf to swap in but don't have the funds or the time to finish that project and really am going to be messed up if i have to rebuild the 4l60e.
Do you all think it is just going out like and age problem. I have 115k on the car. The fluid is due to be changed again. Do you think if i have the fluid flushed and change the filter that would fix the problem or is it much more to it??
Thanks in advance,
Jeff

Sounds like it is going out and probably won't last too much longer. The sluggishness you are feeling is the transmission slipping. I would suggest against flushing the fluid as it will probably make it worse.

I think i am going to do a fluid flush and filter clean. I need to check the fluid again....it was alright last night (old looking though). I don't think it is an acutator spring because it only does it every once in a while. Especially when the car is running a little higher rpm (when first started). Also, it doesn't slip in 4th it just won't go into overdrive anymore. When you let off the gas (doing 70mph), it will then you give it gas again and it down shifts. It feels like it slightly slips when leaving from a stop though. I'll bring it to a tranny shop and get them to do a pressure test. Thanks for all of the sugestions.
If you have any more ideas they would be greatly appreciated.

There have been many threads on the hazzards of "flushing" the tranny.The conventional wisdom is if it is lower miles and running decent it is ok.If your doing it to try and fix a tranny problem you are asking for it to fail sooner.I would go with a change and filter not flush.I also added some Lucas Tranny treatment(there is a lot of debate on this too) to my old tranny before rebuild and it did help it out.

Speaking from experience ( I have gone through several 4L60's ) it is going out. I will reiterate to not flush the fluid, while you may be ok changing the filter and refilling the tranny, I would just leave it alone. When the 3rd gear band goes on the 4L60, it takes all the rest of the tranny with it, and you will be dead in the water. The chances of it being some minor part that can be replaced are slim to none, especially if you have 115k on it, and even so, to pull the tranny out and try to band-aid it is not cost effective. So, sorry for the bad news, but your tranny is going and needs to be replaced or rebuilt.

Don't despair yet. The fact that it's intermittant is actually a good sign. Your symtoms are identical to some I had a while back. Have you checked for codes? Mine was bad connections at the TPS. The transmission gets signals directly from it and if the connections are compromised it will affect the voltage readings that the trans. receives. If codes are present let me know what they are and I'll tell you what to check.

I checked for codes (GREAT IDEA!!!! would have never thought of that w/o a light. Thanks!!!) and i have an H82 shift solinoid A fault code. I don't have my book on the car up here at school. Can someone give me a explaination of that code. And if it is just a solinoid fault, could that be changed out??? Thank you all very much for the help!!!
One more question....I 'm very dependant on the vette for transportation, should I avoid at all cost to drive...could driving really mess something up (I know the anwser is probably yes...but i figure it couldn't hurt to ask.)
thanks,
Jeff

I'll try to bring it by today. But that shift solinoid A is one of thoes solinoids on the valve body. That doesn't sound hard at all to change. Is that right or is there much more to it than that??? And is that the correct defination of that DTC???

I brought it by a shop that seems pretty reputable. He said because it is not shifting in to od that the 3-4 clutch pack is fried. He said this is extremely common in 100k+ 4l60e's. He quoted around $1500. What do you all think does it sound like rebuild time. Would anyone have and idea of how long it could last???

It's one of those how lucky do you feel type situations. If you are really easy on it and baby it all the time, you could make it last for a while. I would also suggest not taking it too far from home because when it goes, you will probably have no forward gears. The last one I had fail on me would barely go 35 at 1/2 to 3/4 throttle and I was lucky enough to be close and was able to limp it home.
