Update, went to talk to the service mgr at the dealer, he acted surprised that I knew what an Oasis was, thanks to this forum! So long story short he tells me there's nothing on the report, clean, no problems. But wouldn't give me a printout. So the kind gentlemen( Maximum 4x4) on the 6.0 PSD forum that I spend most of my time on hooked me up with the Oasis. 4 things on it, most notably trans shifting erratically/ slipping, OD light flashing @ 19,900k mi. Replaced solenoid/ update PCM, OK.Hmmm... that's exactly what I asked him, said I read these things have tranny problems( I read on here). He said Nope, looks OK, no reports. Tire press. light on, replaced wheel speed sensor. That same light was on when we bought it, wife took it back next day, they inflated tires and now no light. Is this something I need to be concerned with since it was on again? I just figured the air press. was low, the light isn't on anymore.TIA- Tim
