Tiptronic Help/Advice
He guys, my tiptronic started not going into 5th from 4th in auto mode. In tip mode, I could shift through all the gears just fine. Took it to my Porsche mechanic & hooked it up to the pst (sp?) tool & it had solenoid fault codes. Changed the fluid, but no change. I bought a used tip & installed it. Shifted fine for about 30 miles. The next morning it was back to being the same as before. Bought a torque converter, installed it, no change. Mechanic said the fluid is perfectly full and the car is not throwing any codes. He thinks i bought a bad transmission. Oh...the used tranny & TC are out of the exact same year box as mine. I'm at a loss. I don't think it's the TCM either, but I don't know at this point. Any help would be very much appreciated.
