At acceleration speedometer will read zero and transmission hesitates to switch gears and now within the last day its doing alot of sputtering and what sounds like backfire when increasing the speed. I've heard that it could be the speed sensor, if im correct, where is it located, is an engine/transmission diagram available for that year
Haynes manual should be easy to find for it. Diagrams are about 1/3 of the back of them.

It's on the passenger side of the transmission just above where the drive axle goes in. What is wrong with car?

Speedometer cluster or sensor. The sensor can be checked on car with a scan tool. This may eliminate that.
