Having problems with your 2006 Ford Expedition ?

"Engine Failsafe Mode" message appeared after down-shifting to D2 when going down a steep hill. Speedometer showed high speeds but only going slow. Pulled over, shut off the engine.

Sincerely speaking from experience, I have had similar problem before.

After which it runs like nothing was wrong before.

It is the throttle body assembly no doubt.

It is worthwhile, let them fix it.

Cheers and don't forget to rate my solution.

Its definitely not the throttle body. This is a serious transmission issue. It sounds to me that at some point during your up and down hill traveling the valve body in transmission lost access to the transmission fluid. When this part of the transmission runs dry it also causes the pump to run dry and instantly fries the transmission. It will give you no sign it will simply stop pulling. This cannot be corrected by changing the fluid. The transmission has now completely failed. Hope this helps. Please re post with updates and questions.
