My 2005 LLY will not go into gear now. I have replaced the NSBU switch and it worked correct for about 10 miles, parked the truck and now it will not go in gear at all. Trans temp is reading 0 and the indicator bar is not on the dash under PRND321. My question is can I swap the TCM from a 2004 lb7 into the LLY to see if this is the issue? Any help would be appreciated as I am stumped on this one.
Thanks
