I dont think its the TCM, Its a tranny issue 230 degree temps from a tranny is NOT normal. Are the techs at your service dept. competent?....Sounds like high temps are being caused by slipping or slipping is causing high temps. Replacing the TCM wouldnt fix this issue....its a bad tranny or something no right

Just my opinion TCM is not the culprit
