What is a tehcm in a GMC Acadia?
This is another flaw in the GM transmission that may have been exacerbated by the wave plate failure. The Transmission Electro-Hydraulic Control Module, often called TEHCM or TCM, is another non-robust part in the terrible transmission on these things.
Why does my GMC Acadia not shift past 2nd gear?
Wrong, suddenly you have the familiar check engine light and transmission won’t shift past 2nd gear. Ahhhhh. You’ll have another P0700 code along with some sort of shift solenoid failure. In my case it was a P0752, but there’s several switches on the module that could fail and trigger similar codes.
How much does it cost to replace a GMC tehcm?
To replace these simple and inexpensive parts, you also have to replace the more expensive parts contained in the rest of the module. GM charges $650 for a TEHCM and the dealer will want $1400 or so for the entire repair. The repair involves replacing the module, some gaskets, and reprogramming the TEHCM.
