adjust transmission bands

How do you adjust transmission bands?


Adjust Transmission Bands

Since the band adjuster has a lock-nut it will need to be removed. You will need two wrenches in order to loosen the lock-nut from the band adjuster. Loosen the lock nut off about 4 turns. Now you are able to adjust the band. Spray a bit of WD-40 on the band adjuster to make it easier to turn. Once adjusted make certain to tighten the lock-nut. Repeat on additional bands if needed.

Hydra-Matic Transmission Band Adjustment

Not all transmissions have band adjustments. No band adjustments are necessary or possible on Turbo Hydra-Matic transmissions; they use clutches instead of bands.

  1. Raise the truck on a hoist or jackstands.
  2. Clean all dirt away from the band adjusting screw. Remove and discard the locknut.
  3. Install a new locknut and tighten the adjusting screw to 10 ft. lbs. (13 Nm).
  4. Back off the adjusting screw exactly 1 1 ⁄ 2 turns.
  5. Hold the adjusting screw from turning and tighten the locknut to 35–40 ft. lbs. (47–54 Nm).
  6. Remove the jackstands and lower the vehicle.
