A/T 4speed fails, car wont move until hot.
#28
if the car dont move cold
unplug the TCM connector and see if it moves now, if not, moving now, then the tranny is bad.
the tcm can not , make the Drive , 2 or L selector go to false neutrals, only to the wrong gear. so its really not your problem the TCM.
but the test can show you the trans does not slip, if you drive like this. right>>?????

need the super secret , manual test mode. THE FSM covers this if you read the full trans chapters.
in that, you drive with the TCM unplugged, force tranny to

1,3,4 shifts.
skips 2nd is normal.

now test cold, and on angles.

if it fails the tranny is bad.
