Classic/Antique Car Repair: 1966 powerglide transmission, center bolt, bolt head


Question
QUESTION: Transmission is solid, but will not up-shift to drive.Have changed fluid, filter, and new modulator, has good vacuum. Will smoke tires in reverse and low, but doesn't up-shift to drive. Thank-you for your time. Wyatt

ANSWER: Wyatt,

I been reading on this Q for 2 days now.

Most of the time its from 1st where low band adjustment comes into play.

The low band adjustment is on the left (driver's) side of the transmission, and sticks out of the case about 2 inches forward of the domed cover, about half way from the bottom to the top of the main transmission case.  

Loosen the lock nut, if present, while holding the center bolt head with another wrench, then, with the lock nut way out of the way, tighten the adjuster with a torque wrench to 6 foot pounds torque, then back it off exactly 3 turns.  

Re-tighten the lock nut now, without moving the adjuster.

Does it just not go or does it go from 1st to high rev? without catching?

Let me know

Mike
