Hey all.

Does the Trans computer throw out any codes on the OBD-II scanner when they go bad or are they tested separately (or just swapped out to test like mentioned in the manual)?

The reason why I ask is:

The Trans has be doing the 2-3 "slight slip" like most of them do (100K miles) and like my last few cars, I knew the trans would soon be on it's way out. It's had a new end clutch and some other work over the years and has been serviced pretty regular. This weekend it finally made a large clunk when I was decelerating and then was slipping. It seems to be in Limp home mode and running in 3rd gear.

It's my wifes daily driver and she's managed to milk this trans for an extra year or so. If it were mine, I'm sure it would have quit long ago the way I drive. (or did drive in my younger days).

I didn't want to chance it so I pulled over and went home and got the trailer. The fluid (which I check every week to keep an eye on it since it's on it's last leg isn't really burnt. It is a tiny bit red vs pink but not too bad considering the car has 112K on it.

I guess my question is: If the computer goes into limp home mode (if the computer is bad and not from a transmission problem), I'm guessing it would'nt burn up the fluid correct?

Given that I've owned 3 autos and the symptom is almost identical, I'm getting the trans rebuilt but I just want to make sure I don't put a good trans in with a bad computer. I guess I would know immediately when it starts out in 3rd gear!.

The car is the 1998 3KGT SL with 100K on the clock. I'm more than capable of doing the work, I'm just a little un-educated when it comes to the transmission computers on these cars.. You hear so many horror stories. I'm guessing when the trans computers go bad, they normally don't burn the crap out of the fluid?? or am I wrong?
