I finally got around to doing my tranny service this past weekend. I replaced the governor pressure solenoid and transducer and of course filter and replaced with amsoil tranny fluid. I also installed a derale deep trans pan. I adjusted rear band while i was in there to. Truck definitely seems to shift better but also seems like it takes longer to shift into 4th. For instance it usually wont shift into 4th until i get above 2k rpms and stay at that for a period of time. Is that normal? I dont really know have only been an owner for about 4 months now and it is not my dd (have a company f150 ).
