Hand Tight then back off 4 turns - Done
It doesn't have a band adjustment.
No. The last transmission GM made with a band adjustment was the Powerglide - gone in 1968, I think.
I have read that the cast iron case added 150 pounds to the Powerglide transmission, and I have also read that the aluminum Powerglide weighs about 95 pounds, complete. I have moved an aluminum Powerglide by hand, and that sounds about right. Based upon these two statements, the cast Iron Powerglide should weigh about 245 pounds...

The shop that rebuilt my '54 Powerglide recommended Dexron III.
The PowerGlide feature is credited to the General Motors company for it's inception. The PowerGlide is a type of two-speed automatic transmission found on many models.

i'm not sure for that transmission, but i know for my trans, (GM 3T40) the band adjustment is the piston itself. if you look at the shaft on the piston, you might notice a couple of lines cut out on it. If so, that's the adjustment.
There is no manual band adjustment in that transmission. It is self adjusting.
Chevrolet & Pontiac were the only brands to use to Powerglide. The rear engine Corvair used a modified Powerglide. Pontiac used a similar transmission in the Tempest although it was called a TempesTorque'. Some sources claim Pontiac and Oldsmobile used the older, cast-iron case Powerglide when the Hydromatic transmission plant burned in '53. Most if not all Pontiacs of the '60's and '70's that have a two-speed automatic transmission do NOT have a Powerglide; they have a Turbo-Hydramatic model 300 transmission; also used by Oldsmobile.
It is a 2 speed automatic transmission that General Motors used from 1950-1973.
The Trans Linkage setup for a 1966 Chevelle with a Powerglide transmission involves connecting the shift lever to the transmission in a way that allows smooth gear selection. It typically includes a series of rods and bell cranks that link the steering column shifter or floor shifter to the transmission. Proper adjustment is crucial for ensuring that the transmission shifts accurately between park, reverse, neutral, and drive. If the linkage is misaligned, it can lead to issues with shifting or even damage to the transmission.
