Having some issues with my trans. When cruising at freeway speeds (60-80) my trans will all of a sudden just rev to 4K and put me into limp mode. Seems to be worse on inclines due to the extra load? Sometimes you can feel a jolt or two before it goes. I thought that the t/c clutch was done for so I replaced the t/c and still has the same issue. When it happens again and throws the p0700 I’ll have to go rent a scanner that will read the Tcm and post back here. Time for a rebuild?
