Step 2: Replace Worn Parts

  • Replace any damaged or worn parts with high-quality replacements. This usually includes clutch plates, seals, gaskets, o-rings, and bushings.
  • Ensure you use the correct parts that are compatible with your specific Powerglide model and year.

Step 3: Reassemble the Transmission

  • Follow the manufacturer’s service manual or a reputable rebuild guide to properly reassemble the transmission. Pay close attention to the sequence of parts and proper torque specifications.
  • Lubricate the components as you reassemble the transmission using the appropriate transmission fluid or assembly lube.

Step 4: Check and Adjust Endplay
