Automatic Transmission Control Module problem #1

Gm transmission control module # 24256861. . . . There are over 9,000 gm trucks that are sitting idle because gm quit making this part, there are no after market replacements nationwide. When this part fails it shifts the transmission into 2-3 rd gear and goes into limp mode which if you are doing 70 on the interstate you are in for a sudden awakening. It also causes other issues like stablitrac issues there are at least 4 other issues which make the vehicle undrivable it is sad that gm has known of this failure for well over year. It should be a warranty item but is not. I just need my truck to be drivable again. . . . .

Power Train problem #2

I was driving down the highway at 75 mph when the transmission control module overheat and put my truck into third gear causing the truck to speed unsafe.
