Scotty , Please help! I have a 2000 Ford Crown Vic P71 Police package with a 4.6L V8 and the 4R70W Automatic Trans.....The transmission is rebuilt and has 60000 miles on it now....I have serviced the trans every 20000 miles dropping the pan, and using the correct fluid and filter. The problem, the overdrive light started flashing recently. Only when the tranny is good and hot and I am stuck in stop and go traffic (about 15-20mph) or while sitting in traffic for a short period of time (2 minutes) while the vehicle is in drive. Once moving again the car with stay in limp mode for about 30 seconds (slow acceleration/ no power) until it get over 40mph, then the light goes out and the car is fine. I have replaced all three shift solenoids sensors (inside the pan on the bottom of the valve body). I replaced the vehicle speed sensor, as well as the output shaft speed sensor....the fluid is pink and I have never found any metal in the pan. The vehicle shifts fine and runs well...The engine was also replaced and has the same mileage as the trans (60000)..... I served in the US Army as a mechanic and my father had a shop that I worked in as a kid so I am pretty decent a fixing things....but I give up?? I took it to my local mechanic and he couldn't figure it out....again it doesn't seem to slip at all and seem to be shifting fine....any ideas??? Thank you for your help!
