Transmission problems with no speedometer or odometer
I have a 1994 F350, 7.3 Diesel with E40D. I had the transmission overhauled about 30K miles ago. Now the transmission shifts roughly, jerks as you accelerate and sometimes when you de-cel. Drives normally at a higher speed. I also do not have speedometer and odometer not working. I checked the fuse at the fuse box, fuse is not broken. I talked to a mechanic who told me it could be a speed sensor, located on the rear axle housing. Is there a way to check the sensor without purchasing one and finding out that is not the problem. What else could be the problem? Any help is appreciated.
