Hey people, i just did my T-5 swap, and the donor car was an 85 Trans Am that had the mechanical drive speedo- well my car is a 91 Z28 that has an electronic drive that needs a speedo sensor for the 91 Z.. well i got that, and i hooked everything up- it fit perfectly, but my speedoeter still doesnt work?? whats wrong?? i tried disconnecting the battery so it would reset the ECU, but nothing still- help people, i dont know how fast i'm going

 

While you're down there checking wires, make sure the teeth on the driven gear are engaged with the drive gear and that they haven't eaten each other up.

 

the speedo sensor itself has one gear that slides on the shaft- is there another gear that i need?? i thought it just 'plugs' into the output shaft and is driven by that- is there some other gear that i need to pull out of the auto tranny?

 

There's a plastic ring-shaped gear that slides over the output shaft and is retained with a small metal clip. The drive gear.

The driven gear is a mushroom-shaped gear attached to the VSS unit. Also plastic.

 

how do i get that out of the auto tranny? do i have to take it all apart? or should it just come out- i have the gear that goes over the shaft of the sensor

 

just a quick question- i would need the gear out of the auto tranny, right?
