ok. I took a 700r4 out of a 91 astro van and swapped out the tailshaft so I can

[Kyle G]

use it with my 92 camaro.? so basically there is a speedometer gear on my original 92 700r4 transmission but there wasn't one on the 91 astro van transmission. same electrical connectors on the tailshaft only difference again is there wasn't a speedometer gear on the 91 astro van transmission tailshaft rod. Can I put this gear on the 91 700r4 so my speedometer works again. By the way its a clip that holds it in and kinda like a big twizzler gear the stays on the tailshaft rod.

yeah thats the speedometer worm gear, youll need it to keep your speedo accurate. take all of the electrical stuff, since your camaro is 91 and up, it uses electronic speedo. instead of cable
