Transmission and Driveshaft

Welcome to the Transmission Section! This section details how to swap in a late model transmission, modify a crossmember, fabricate linkage, install a cooler and more:

X-Member - This page talks about how to modify the transmission crossmember to swap in a late model transmission


Shifter - This page discusses how to machine up transmission linkage from the tranny to the shifter


Kickdown Linkage - Here's how to connect the transmission kickdown linkage from the tranny to the carburator which in this case is a Quadrajet.


Calibrate - This page talks about calibrating the speedometer to your rear end gears and selecting the right speedo gears to make it accurate.


Cooler - Here's step by step installation procedure for installing a tranny cooler


Radiator An automatic transmission needs its fluid cooled and you must have piping running to the radiator


Driveshaft - Swapping in a newer transmission into your ride usually means shortening or lengthing the driveshaft. Here's the info on how to do that.

Modifying B&M Unimatic Shifter - The B&M Unimatic floor shifter doesn't come with a backup light switch and there's no kit to add one so here's how to add a backup light switch and improve the shifter too!
