O/D Light Still Flashing- Help!!!
I own a 98 F150, 4.6L, 4x4, 4R70W transmission. I had a post a few months back about a flashing O/D Light. The light only flashes after about 20 minutes or so of constant driving. Around town on short trips, nothing. When this started a few months back I pulled the code P1500. I had a few people tell me to change the sensor on the rear-end. So, I proceded to change the sensor on the rear-end. Drove for a few days, around town, so no flashing because I hadn't taken a long trip. Next day, transmission goes out. Clutch band blew apart. So, I ditch that tranny and have a new one installed. Took two months because of warranty fight. So here I am today, take a 45 minute trip and the light begins to flash again. No harsh shifts like before. No speedomenter issues like I've seen on some posts. Truck runs fine, just a flashing O/D light. I don't know what to change next. I contacted my Ford garage and they will gladly help out. Of course it will be $70 just to hook up and read the codes, which I already know. Then $50 an hour labor after that. So, anyway, trannys brand new (rebuilt) and rear sensor is new. Any thoughts. Thanks
