How to 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.
