1967 Chevrolet G20 Van Performance Transmissions

The B&M Transpak is the next step up from the B&M Shift Improver kit. It has all the features in the Shift Improver kit, plus it provides additional driver manual control (GM TH-400, 350, Ford C-6 and Chrysler Torqueflite only). B&M Transpak kit for 1965-1987 GM TH400/375 automatic transmissions. Most stock automatic transmissions won’t downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear you’re in. With the Transpak, you can downshift at any speed, and you can hold the transmission in first gear to any speed that you want! This is an asset when you’ve got a modified engine, and you want additional RPMs, or you’re towing a trailer or driving heavy loads downhill. Stage 1. Heavy Duty is for street rods, normal passenger vehicles or other heavy duty use. Firmer shift feel but not harsh. Improves transmission performance and life dramatically without loss of comfort and offers normal automatic operation when in Drive. Stage 2 is for Hi-Performance street use. Essentially the same as Heavy Duty mode except shifts are much quicker. Retains full automatic features and standard shift points with selector in Drive.

The B&M Master Racing Overhaul Kit includes all gaskets, seals, bushings and high performance friction materials. No transbrake body gaskets or instructions included.

Constructed of durable polyurethane to handle the stress oh high horsepower. Absorbs vibration and lasts longer than rubber Features unique built-in safety lock to keep from separating under high torque loads. Ideal for use on street or strip applications. Complete with grade-8 mounting hardware.

A true performance application component for cars, trucks, hot rods. For racing/competition, yet popularly used for street vehicles when more horsepower is added. Soft running enough to absorb vibrations for street use yet rugged for racing use. Helps control torque on high performance vehicles. Maintains proper drive shaft angle to help prevent early wear and unexpected power train damage. Replaces the original, short lived and typically too-soft rubber mounts and outdates those hard-running metal transmission mounts. Resistant to under vehicle fluid oils, coolants and road contaminants. Made of Energy’s Hyper-Flex performance polyurethane and heavy duty hardware – for added durability.

Mr. Gasket Solid Steel Motor Mounts are recommended only for competition applications. This .180 inch thick, zinc dichromate plated solid mounts do not have the flexing present in rubber or even polyurethane engine mounts. This prevents lateral engine movement or twisting in high horsepower and torque applications. Nor will steel mounts break as easily as stock rubber mounts can. Engine movement in applications like this can cause contact of engine components into places they do not need to be (like headers hitting the frame of the car). Also engine twisting can cause severe drivetrain misalignment affecting shifting or even power transmission to the ground. However, without the insulative effect of rubber, vibration can be substantial and thus solid mounts are not recommended for the street.
