My HMMWV M1152 A1 keeps going into limp mode. It's had this problem since the very first day I picked it up from Gov Planet.. im now 3 months into trying to diagnose the problem. I Replaced input and output speed sensors. Ive had a total of 7 different mechanics take a look at it. Most have never had hands on with a HMMWV so they aren't sure how to navigate the wiring. The last diesel mechanic suggested i swap out the TCM. I swapped it out with an identical TCM-2100AB but it hasn't resolved the problem.. Does anyone have any suggestions? Is it possible the wrong TCM is being used. My transmission reads GTP P/N 24208021. As much as ive searched the internet, I can't find the TCM that matches that specific tranny. ![20210619_122138.jpg 20210619_122138.jpg](https://www.steelsoldiers.com/data/attachments/592/592667-f9cd77eaa56cb860dce86fa38ad93ea8.jpg)
