Speedometer Wont work?
I have a 91 D150 Rwd, with the 5.2. i just got it yeasterday morning, and the speedometer does not work. i found what i think is the sensor by the tranny but i dont think its bad the wires seem pretty solid and the speedo will come on and off while im driving ussually when im on a bumpy road. sometimes it works for 45 seconds some times a full 3 mins, but i dont know how to troubleshoot or fix it... i was wondering if anyone could pass on some information on where to check and what im looking for that could cause this. i dont think the gears are bad because it actully works fine when it does work. also on a side note the ABS and break light are staying on , not sure if that helps any?

You really cant turn it back unless you are skilled in that procedure. If you get a new one you can prep and affidavit as to your actual mileage and have it notarized and send both units to a speedometer repair shop. They will set your odometer. Pretty cheap. Your new one will likely have a lot more miles. You should note however that I believe the odometer is separate from the speed reading. If both your speed and miles are not working the odometer gears and/or wiring at the back of your transmission might have failed also but you wont know till you replace the unit. Pull yours out first so when you go to a junk yard you can do it quickly.
