I just finished swapping in a 5-speed in my car and I need the correct VSS for the car. The car is a 91' with TBI, the trans has a VSS for a TPI car in it now, so I went to the dealership to try to get the right one and they list two different ones for the 5-speed trans for a 91 car, one for rpo D8N and the other is for rpo D8I and they couldnt tell me which was which.Can someone tell me which one is for the TBI 5-speed option? I tried looking up the codes but they all just say (Sensor,Vehicle speed)

 

Does anyone have a clue,part number or RPO number!!!Any insight would be great. I know a bunch of us have done this swap, someones got to have a part number for a vehicle speed sensor for a 5-speed with a V8 TBI.

 

Your 91 TBI equipped with a 700R4 came with 2.73 rear end gears. The closest VSS for a T5 would be for the would be from a 90-92 with 3.08 rear end gears. Maybe the drive gears could be changed to make the ratio you need.

 

I appreciate the reply but I think you got the wrong idea, Im not concerned with the speedometer being off , Im getting a VSS code 24. Someone told me that there are 2 types of speed sensors, a TPI speed sensor and a TBI speed sensor. I need this cleared up. I have speed sensor P#10456087 in the car now which is from a 3.08 geared car so the ratio should be close and it throws a code. This trans also came out of a TPI car and mine is TBI. I need to make sure I either have a bad sensor or the wrong sensor! The speedo does work, its just off and the car throws code 24.Any help would be a *** send.
