I would like to know the location on the transmission of the speedometer sensor (Speed sensor). It needs to be replaced and can't seem to locate it easilyon the trans. 1999 S70. An error code of P1057 come up, along with most of the right hand side of the dash warning lights come on. It seems to be intermittant, also the speedometer drops to zero and the odometer reads -------

Welcome to MVS.

What leads you to the conclusion that the "speed sensor" needs to be replaced? Are you getting a CEL and associated error code? What's the code?

The 99+ cars don't have a VSS (Vehicle Speed Sensor) in the traditional sense. The computer network uses the speed as detected by the ABS module to show the speed on the instrument cluster display. If your speedo is doing odd things, there's a good chance there's a fault with the ABS module, it's pretty common on our cars.
