Transmission & Transfer Case

This page covers the parts around a transmission and transfer case rather than the gearboxes themselves: shifters and their bushings, mounts and supports, linkage for automatics, transfer case shift knobs, and the hose that runs to a transmission cooler. It mixes off-road and street parts, so start with the job you are doing and ignore the rest.

For a manual gearbox, shift feel comes from three places. A short-throw shifter, such as those from Fidanza, shortens the lever travel between gears. Shifter bushings and stops from Perrin Performance and COBB replace soft factory rubber with firmer material so the lever moves less in its base. Transmission mounts and supports hold the gearbox itself still, which keeps the shifter from moving when the engine rocks under load. Fitting all three gives the most direct shift; the trade is more vibration and noise in the cabin.

On the four-wheel-drive side, Rugged Ridge supplies transfer case shift knobs, drivetrain kits and transmission access covers. For automatic transmissions, Edelbrock makes linkage pieces: a kickdown stud, a rod extension, and a cable adapter for the 700R4 and 4L60 automatics. Derale sells transmission oil hose in 11/32-inch and 3/8-inch sizes, sold by length, for running lines to an added cooler.

Many of these parts fit by transmission or shifter design rather than by vehicle, so read the application in each title. Listings with vehicle data include older Chevrolet C10, Chevrolet K10 and Chevrolet K20 pickups and GMC G1500 vans. Each product page lists the years, makes and models it fits.
