tranny broke

[Lenard]

well i figured it would happen and it did, going to work this morning driving thru downtown Kansas city running around 40 mph and the tranny slammed to 1st gear and that was it. i stoped checked fluid it's good, started back up and all i had was 1st and reverse. just had it towed to clinton, and drove it again, and had all gears, shifted just fine no problems. WTF? :wall:

bad trans computer?

Have you been having tranny problems? Your post indicates that you expected it to happen. Why?

 

Shifting of the AW-4 is electronic, controlled by the TCU and also by solenoids. The factory troubleshooting method is to pull the fuse for the TCU and test drive. You'll lose second gear, I believe (or first). Other than that, you shift manually. Try that and let us know if there are any glitches.

In this thread Lenard discusses his ongoing problem before this current happening.........

Eagle and others with long time knowledge on the AW-4:

 

Does the TPS sound like a likely culprit considering he says that it shifted fine after having it towed? Or maybe the tranny computer with a hit/miss electrical connection (or a part going bad with heat)?

 

Funky issues start then get more frequent but are not always present doesn't sound like mechanical (if it's broke, it's broke all the time) but rather electronic (heat, cold, vibration, etc. issues to consider here) in root cause. Am I leaning in the right direction on this or am I all wet?

i expected it cause its just my kinda luck.... but anyway, the day before all this happened i backed out of a parking spot and put in drive and it didn't do anything, thought i was still in N so i dropped to 3rd, still nothing, it took it over a minute to finally find a forward gear. to me thats something mechanical inside the tranny, but all the other problems ive had make me think electrical. i would try that Eagle but it's 2 hrs away now, and it never does these problem any certain time, like with the torque converter acting up, i drove as far as 300 miles with out it acting up, and the next 100 miles it was acting up all the time.
