Vehicle: 1992 Lumina 3.1L v6, 3T40 transmission, 83K miles on odometer.
My problem is that my speedometer is going flaky. Sometimes it won't register any speed after a green light, other times it will be fine until higher speed where it will slowly dip back to 0.
I've made the observation that when the speedometer is not registering any speed, the odometer is not moving either. From this observation I believe that I can say that the speedometer unit is not directly at fault.
Are the speed sensors on these transmissions known to be flaky? Or maybe the wiring from the sensor?
How hard is it to change the speed sensor on this model transmission?
Any advice is appreciated.
Thanks
Scott
