1985 GMC Jimmy Transmission Swap - Go From This, To This! Photo Gallery
One thing we should have checked before we started was the speedometer gear adapter. This goes in the back of the tailshaft housing and connects to the speedometer cable. Unfortunately, the original (right) was longer and smaller in diameter than the B&M 700-R4. We picked up a used one (also for an '85 Camaro) for around $30 at a trans shop.
