Hello and welcome to JustAnswer!

If there is no vehicle speed sensor signal present yet the sensor has been replaced twice then odds are there is a wiring issue. It's possible that there is an issue in the trans and the gear isn't being driven but that isn't likely. Odds are there is a wiring issue, assuming that you're getting good replacement sensors.

Has there been any damage to the drive gear?
Has the wiring been tested?
