Have you replaced the speed sensor? Also I still think you need to have the stepper motor replaced in the speedo head. A bench test is not reliable for this type of instrument.

Either the gauge is bad, the cable is kinked or the speedometer connector is bad...at the tranny.

How to fix a speedometer cable


Well you know it does not have a speedo cable since you replaced the speed sensor in the transmission.
My guess would be a problem with the speedo or cluster.

Nissan Maxima speedometer reads 20 mph but actual speed is 40-50 mph, is my transmission going bad?


NO, IT'S NOT THE TRANSMISSION! SOUNDS LIKE A SPEEDOMETER PROBLEM! THAT WOULD BE ONE OF THREE THINGS! EITHER THE SPEEDOMETER, THE CABLE, OR THE SPEED SENSOR! THE SPEED SENSOR WILL USUALLY GIVE YOU A P0500 CODE ON AN OBD-II CODE READER! THE SPEED SENSOR IS ELECTRONIC SPEED CONTROL LOCATED ON THE TRANSMISSION! SOME HAVE A SPEEDOMETER CABLE HOOKED TO THEM, AND SOME JUST HAVE A 2 WIRE PLUG THAT HOOKS TO IT!

Ok my 1986 Fiero 2m4 wont come out of reverse it was hard 2 shift gears all day yesterday until about 4 o clock now the transmission shifter just moves around freely but like i said its stuck in reverse...


Manual or auto?

It's gotta be the cable/linkage. You just have to inspect them and see if something is worn or snapped. They get old and crusty and need to be replaced eventually. I had to replace my shift cable on my 86 se with the 5-speed getrag.

Hopefully it's not the actual tranny....?

2001 pontiac grand prix with speedometer intermittently inoperative.


Hello! It sounds as if you have a wheel speed sensor that is failing. The wheel speed sensor calculates the wheel/tire revolutions and sends this information to the speedometer, which then displays that information as MPH/KPH. On 97-06 Grand Prix's this and the ABS sensor are the same module, and in order to replace, you must replace the entire hub assembly. Here is a view of the hub assembly from the back side of the hub/wheel assembly. You may want to inspect the sensor wires for any fraying, loose connections, etc.

I'm having a problem with my 1990 Volvo 740's speedometer. It fluctuates erratically and the odometer does not work either.


Check the connection at the speed o sensor. It's in the differential cover, about 3" above the filler plug. Be sure it's mechanically secure, and check the contacts (both sensor and connector) for signs of corrosion or oxidation. As much as possible, examine the harness for any signs of a break or tear, or for signs the wire might have been cut. If it's not wiring, then it's either the sensor or the speedometer head (which is electronic). Possibly, the power supplied to the speedo head where it's mounted in the dash cluster is intermittent. The speedometer in my 745 with 160K has been jumping around a little on the highway. The cruise control would try to follow the erratic speedometer, then disengage. I suspected a broken wire at the sending unit. What I found was a burnt wire at the sending unit. The wire had grounded out on Volvo's safety wire. I suspect that the safety wire slowly eat through the insulation on the wiring, causing it to ground out. The plug was melted and an inch or so of insulation on the green stripe wire. Make sure the safety wire is not cutting into the two wires on the sending unit at the back of your rear end. [Response: Scott] Check the instrument cluster grounds under the dash and in the right footwell. In 88 there were some 700 series cars that would register up to 60 mph while sitting still and the grounding problem was the cause.

Cummins Diesel Truck Erratic Speedometer and Shifting


Although you didn't mention it, the speedometer probably bounces also. Replacing the speed sensor on the side of the transmission should solve both your problems. Good luck
