I have a 2005 Ford Explorer XLT with 4.6L V-8 engine, 4 wheel drive. 249,000 miles. Been a good vehicle. Yesterday (Saturday) my wife was driving it when the coolant port cap blew off of the Dorman intake manifold I put in about 2 years ago. I knew it was a possibility. She drove it as it overheated and car shut down. She fortunately was able to coast into a gas station. We towed it back to our house, where I replaced the port cap and refilled with antifreeze.

After going through the coolant refill process, I went to take it for a drive. Put car into drive but it will not accelerate. Put it into reverse to back it into the driveway and again it revs but doesn't go anywhere. I have found that if I take it down to 3,2, or 1 on the shift tree, it will go. Would these issues be related? I wondered if it might be the tow. It was the kind of truck that lifts up 2 wheels and pulled my vehicle behind, but he jacked up my rear end and put these temporary tires under and my vehicle rolled home on those. I don't feel like the car overheating would have affected the transmission. But I am hoping for some feedback. Thanks in advance

I can't see how this overheating would affect the transmission and cause it to fail.

The transmission problem you are having is a classic failure we see with this transmission, unfortunately this failure will require the transmision to be removed and basically be rebuilt. There is a component called the input sprag and when it fails (usually without warning) you will lose both forward and reverse engagements but will pull forward in the lower manual gears.

James thank you for your reply. It's about the worst news I could have hoped for. Appreciate your feedback nonetheless. Are you suggesting the overheating caused this input sprag to fail? Or it was just its time no matter what? Greg

Thanks. I kind of mis-read your 1st reply..
