Friend's 2004 6.0 PSD with 205k, no tuners or chips, never pulls a trailer. The Torqshift 5R110 tranny started acting up. Not exactly sure what is up with it. First thing, when everything is cold, the truck will drive fine. After a little bit of driving, the truck starts acting like it is slipping and can't really find a gear. Tow/haul starts flashing. Tranny is not getting hot. Next day when cold, it shifts fine again at first. Advanced can't pull tranny codes. He took it to the local Stealership. They do some testing a say the tranny is junk. They want $3600 to put a salvage tranny in or $4600 to put a rebuilt (3 year warranty) in. Is he getting buffaloed here? I kinda think so.... Your thoughts?
