I checked for codes today for my tcu. I did get one clear one before my hand got tired. I got a code 86 which is incorrect gear ratios. What could be causing this. Transdude any help you could give would be greatly appreciated.:confused:
 
Incorrect gear ratio codes are usually caused by a slipping trans component, a pulse generator problem or (rarely) a bad TCU.
