stuck in first gear

[Tigerhorns]

I have a 91 Fwd auto talon. Yesterday i was driving down the highway, and the car started jumping in, and out of gears. I pulled over let the car cool down for about 20 mins then i continued on. About 12 mins later the same thing happened, so i let the car roll down the hill under a bridge with some shade let it cool off for about an hour, and made it the other 40 miles i needed to go. I thought the problem was, because i had autozone dextron in the tranny, so i swapped it out with some mitsu fluid(btw the fluid was nice, and red didn't smell burnt, and no metal in the fluid) did the timing belt, pulleys 90 OFH put some new cam seals in, and got my friends lucky screw driver, and made it home.

Well today i wanted to drive my girlfriend around, so i took her out in the car wanted to boost more then 10lbs since i thought i fixed the problem, turned it up to 20 did about 5-6 nice pulls, and everything worked fine. Well i later on in the cruise i punched it again, and it started acting up jumping in, and out of gears. I stopped the car walked to where i was going, came back about 40 mins later, and it was stuck in first gear. I was wondering if anyone would know why the car is now stuck in first gear. I have a guess at what might be wrong, i'm just taking a guess, but i think it may be the speed sensor, but i don't know how there suppose to be hooked up, or anything like that.

Btw i'm going to check the tcu you tomorrow if it is bad, anyone know where i can get on at?

Any luck when you peeked in at the TCU. The caps in a TCU's leak just like the ECU's do. If your TCU is bad then you would be in limp mode (stuck in 3rd gear) you would only have (Park, Reverse, N, 3rd gear). Have you inspected your cooler lines to make sure that trans fluid is flowing threw it to be cooled? If your sure your stuck in 1st gear I would suspect it to be a valve body issue with either a sticking valve or solenoid.

If your in need of a new valve body, front pump, or a whole FWD auto trans I have one. Just PM me if you need parts if yours is bad and need them for cheap.

To be honest no i havent check my cooler. I did take the TCU out, and everything looked good i found out it was for a 90-92 AWD though . Heres a link so you can take a look at what i have found out, if you would like to offer some more help. I need all the help i can get http://www.dsmtuners.com/forums/newbie-forum/400065-91-auto-transmission-problems.html
