Ok, if i swap a Non-WC T5 out of my 84' Z-28 for a WC T5 from a 88' IROC, are there any differences with the speed sensor? Are the ones out of the newer cars electronic? Or is that on for automatics?

 

The electonic sensor and the cable drive thing are directly interchangeable. Unbolt the one (one 10mm-head bolt), pop it out, put the other in. Done.

 

Thanks buddy. Good to know, I found a nice trans out of an 88 IROC with only 58k on it.

 

Yup, it's too easy.... I'm running a 91 T-5 in my 83 car right now.

I actually went to the dealer and bought a new driven gear housing though.... the OE one is a particularly low grade of chinesium, but the new one is steel. All of the OE ones I had on hand (a considerable number!!) were so badly worn out into an oval that they wouldn't hold the gear in proper alignment, and as a result my speedo was intermittent. The worst thing was, that in 5th gear and 5th only, when the car was coasting the speedo would work, but as soon as I gave it any gas, it would go to zero. Made the cruise control pretty interesting.

 

Just picked up my new trans: 91 T5 with 70k on from a bone stock RS. I got to see it BEFORE they cleaned it, and it was really clean.

Ok, I noticed there is another electrical connecter besides the speed sensor, what is that? I think I've seen it on my stock 84' T5 but it's not hooked up.
