Wont shift when tranny is warm

I have a 95 tbird and When the tranny is cold it will shift 1st-4th but when it gets warmed up it only shifts 1st and 2nd. I changed the solenoid, filter, gasket, and fluid and now it does this and leaks. Anyone know whats up? I think i can fix the leak with tightening the pan some more but im more worried about the shifting problem.

No before it only shifted in 2nd and 3rd. Thats why i changed the solenoid pack. Now it work only when its cold and when it gets warm it goes into neutral instead or 3rd or OD.

Patience

Patience, young Jedi. Most people use computers as the tool they are and most likely haven't seen your question yet. The suggestions with come, they just take longer than 24 hours - this isn't cha-cha or KGB.....lol

Personally, I don't have any good ideas or I would have already told you.

Have you been reading through the Transmissions 101 article ??
Check the Common Problems, and Diagnosing Transmissions Problems sections of the 101 article.

Im thinking ... failing Intermediate one way clutch based on what you have described.

Alright got under the car today and fixed the leak. Then i took it for a 10 in drive and everything was working perfect. When the car warmed up and i accelerated harder, when in OD it just went to neutral. This time i kept 3rd though. And also is there too much oil in when i take out the dipstick and the fluid goes half way up the dipstick? Thanks

Way too much .. it needs to be readable on the little indicator on the bottom of the dipstick.

Fluid expands when warm. so if its already overfilled then you get it warm it is even farther over filled.

When a transmission is overfilled the oil gets aerated ( full of bubbles) and can cause erratic shifts. Could this be your problem? yes. am i 100 % sure? no. is their a bunch of bubble's in the fluid when you check it?

Well i just checked and there were no bubbles on the dipstick but fluid was on it all the way up to the middle. Would I have to drain all the fluid and get more or can i reuse it? Cause its pretty expensive for mercon v. Or what do you recommend i do about it?

Did you drain the TC also ? Or just drop the pan and fill it up with 8 quarts ?

Do you still have the stock 95 pan, or the 96 + ?

No i didnt drain the TC, and i did just drop the pan and add 8 quarts. I also have the 95 pan and flter. I just drained most of the extra tranny fluid and i have the same problem. I think it needs a rebuild or replace. I dont have the money for either

So cold it goes 1-2-3-4, but warm is goes 1-2- and then NEUTRAL....if that is the case, that is bad, and a sign of direct clutch death.

Agreed.
What did the fluid look like when you first dropped the pan? Was there a bunch of crap built up on the magnet?
Maybe go find yourself a good used tans from the junkyard.

First time i dropped it the magnet had alot of black build up on it. So do you think that i should just get a used 95 tranny for 250 at my local junkyard? What would be the best option?

If you plan on keeping the car - buy a good transmission or have one built up.

If you dont care and plan on getting rid of the car .. junkyard transmission might work for a little while.

Having one built up is def. the best way to go if your gonna keep it because their is no such thing as a "good" used 4R70. IMO if its got more than 60K on a stock 4R70 its gonna need a rebuild in the near future anyways
