Whats up yall. I need some help finding the vehicle speed sensor on my car. Any help would be highly appreciated.

If they did it the same in 1990 as they did in 92+ then it should be on the transmission at the differential end (where the passenger side axle comes out of the tranny).

Here'* a pic of me holding a chunk from my old tranny next to a 1993 4T60E HD tranny. The sensor on the chunk in my hand is the speed sensor -look at the transmission to get an idea of where the sensor is on a complete tranny.

Good luck with the task -might need to put the car on a hoist.
