Geez, I wish I'd read all this 6 months ago. My '02 Explorer's O/D and engine light started flashing on and off around 60,000 miles. Since I'd just paid an arm and leg for the 60,000 service, and since lights kept going off, I didn't worry. Now my car has been at the dealer for 4 days and they've only now figured out the transmission needs to be replaced. They seem to be giving me a big discount compared to what it could cost, but if this is as big a problem as it seems from reading these posts, we shouldn't have to pay a dime. I'm going to dump this lemon as quickly as I can!
