Just got this code and want to know where to start looking for a problem. I know its a TCC malfunction of some sort.

The transmission seems fine and shifts good and T.C. locks up normal. I wouldn't know there is a problem if the light wasn't on.

I just rebuilt this transmission myself over 10,000 miles ago and it's been flawless until now with this code.

I replaced:

All clutches.....full rebuild
New torque converter from REVMAX
New valve body from Mopar
Installed complete shift kit
Mag Hytec trans pan
Installed Overdrive software with MiniMax
Installed new sensors on outside of transmission


This transmission has not been abused. Easy driving.

I was towing a 28' enclosed trailer with a race car and four wheeler in it when light came on.......60 mile trip. Didn't push it at all.

**First time I've towed anything with it since rebuild and the check engine light comes on**
