    Hi I have a 99 classic suburban that the motor went in tranny is fresh, but I have a 99 k1500 the tranny went out in that I am doing for a buddy. Question is is there in internal difference in the 2 trannys ? I realize there's different in converter,input shaft and bellhousing I've herd there...
