Thanks very much.
Yes, you would expect a 309 if the encoder was bad. That's why I was a little relieved to see an electrical fault. Even if it was the TCCM at $700 a pop! At least the tc wasn't smoked in that event.
But now you've got me concerned. So tomorrow, I'll take it to the car wash and see what their reader says. Also, put it up on the lift and check the fluid, and change it. Although,iirc, they may not stock the special fluid.
Edit:
From the User's Manual:
DexronŽ-III Automatic Transmission
Fluid. Look for “Approved for the
H-Specification” on the label.
So:
Wondering what to do if the fluid is fried. Leave it in the transfer case as evidence for the dealer to confirm?
Or: change it and risk his denial?
Thanks again!
