1996 - FORD PROBE SE 2.0L 4 CYL AUTO TRANS
150,000 MILES. Trans was rebuilt at 100,000. Had a seal go at 130, 00 replaced. Now, at around 25 - 30 MPH the xmsn shifts out of gear, accelerating does nothing but rev the engine, the trans then shifts to second (it's like its searching for a gear) and the over drive light flashes, it shifts back to 3rd then the process starts over. Placeing the shift lever in " 2" keeps the trans in that gear and the car is driveable at low speeds. No codes are displayed using a scanner. Using a Haynes Manual trying to locate the variable speed sensor, not where the book indicates. CANNOT FIND IT! I've been told that the O/D clutches may be bad & the trans needs ANOTHER overhaul. ANY HELP WILL BE GREATLY APPRECIATED.
