The Powerglide 2-speed automatic transmission was originally designed in 1950 by General Motors for use in Chevrolet automobiles. In 1963, a revamped Powerglide transmission found its way into the marketplace. This version featured an aluminum case and components instead of the previous version's cast iron ones. This lighter transmission is still in production and has become a popular choice for the racing circuit. Using direct drive instead of torque converter can increase efficiency and eliminate transmission slippage.
Disassemble the transmission. Inspect the Powerglide core condition. If necessary, scrape and degrease the Powerglide core. Align and square the hose clamps per the owner's manual. Set the transmission on its pan. Remove the tail shaft housing, speedometer gear and governor assembly. Remove the torque converter per the model's instructions.
Install the hose and valve kit per the kit's instructions. This bypasses the front pump. Install the pedal valve body kit per the kit's instructions. This connects to the solenoid, replacing the torque convertor's modulator. Install the low-gear push start kit.
Reconfigure the reverse setup to compensate for additions made in Step 2. Slide the 5/32-inch drill bit into the electric drill's bit cylinder. Insert the drill's tightening key into the cylinder and turn it clockwise until the bit is secure. Consult the owner's manual and locate the reverse piston. Place the drill bit's tip against the 1/8-inch hole in the center of the reverse piston's bottommost side. Squeeze the drill's trigger to widen this hole.
Reassemble the transmission. Replace the governor assembly, speedometer gear and tail shaft housing. Replace the Powerglide core. Return the transmission to the automobile.
