I rebuilt my 4r100 myself (first time). I used the atsg manual and went ahead and installed a transgo reprogramming kit(e40d-hd2-d) while i had it out. i was very methodical about following the directions and the job did not seem that difficult to me but i must have still made a mistake. It goes into first and reverse but slips. and i have nothing in drive. my line pressure was ok until it warmed up then dropped from 60 to 45 psi. plus i hear some clicking when shifting gears. the orginal rebuild was because the coast and od snap rings popped off and the coast clutch was grinding. any ideas were to start would be helpfull!! 2000 f350 5.4 gas 4r100 tranny non pto
