Question about Cars & Trucks
Would like to know why speedometer stop working but tach is working and why trans refuse to down shift only after a 10-20 min warm up then after sitting for 10 mins it does the same thing again. where is the speed sensor located?
You are right in thinking of the speed sensor. You should also have a check engine light on if the sensor has failed.
The sensor is mounted in the side of the transmission and takes the place of the speedo cable.

Good question! My Cabrio's odometer works only when the outside temps are really cold... that means about freezing temp. My VW repair shop guru guy says that the Cabriolet is notorious for this failing. Since the odometer is driven through a small gearbox via the speedo cable, I suspect the odometer "transmission" is mostly kaput. The tach is also mechanically driven so it also may have a semi-functional cable. The only way to really know is to pull the cable and check it for damage. As far as the trans goes have you tested it for codes?

Hi, I have a trooper also, I am pretty sure if it has a speed sensor it would ;located on the transmission near the tailshaft. Not sure that will help, but mine is a standard, so I can't look for you.
or the transfer case maybe?

This is a tricky one. You have two sensors for your speedometer and tachometer, if one is malfunctioning then both will. Check and replace if necessary, good luck
