after 99600 miles on this rebuilt transmission the main shaft went , I was going up a grade and slowing down the transmission shifted into drive and I threw in lockup the tach went all the way to the governor. I know what I won't do next . Call Dave Goerend told him of my problems and he sent out a new torque convertor , how can you beat that for service, called Monday and arrived on Wednesday if only I could get the transmission shop to move that fast . Might get it back by this Monday . Watch that mystery switch. :{ :{ :{
