Question

I got the code U0101 on my 2007 Cadillac Escalade, where is TCM located?

Answer 1

U0101 Lost Communication with Transmission Module

The location of the TCM is near the front radiator

U codes sometimes appear after a repair and may not have any associated symptoms, it usually erases themselves automatically after a number of fault-free ignition cycles. U0101 may have been set due to the low battery condition.
