Bringing this back from the dead....
My trans has been gradually getting worse, but no solution yet. Everytime I've taken it in (3x so far), they couldn't duplicate the problem....and diagnosis is $80 each time!
The O/D light on the shifter handle started flashing today so hopefully they find the problem this time. It wouldn't shift up to O/D at all even on the expressway. At light throttle it hangs up to about 5k then slams into gear. The trans also slips badly in all gears and if its floored, won't upshift at all....just swings the tach past the end (6500+rpm) and hangs there till I let up. I wish the damned thing would just die. Something has to throw a code or completely fail, otherwise they refuse to tear it open. Extended warranty runs out next week.
My Xcal2 program fixed the shifting problem for awhile, but now even that doesn't help. I went back to the stock program to see how bad it is and its a PITA to drive now.
If they don't fix it this time under warranty (or just band-aid it to make me go away till it runs out), about how much is a replacement 5r55E? How much would a complete rebuild be? Should I just try to renew my extended warranty if available and keep taking it back in?
