Powerglide
(Aluminum case)
Used 1962-73 in Chevrolets.
This was an hydraulically controlled
two speed transmission. Some were air cooled, but most had
cooler lines that went up to the radiator. Chevrolet also made a
fully manual version that they called a Torque Drive and used it in
some four cylinder Chevy II's. The aluminum Powerglide shared a FEW parts with the 1964-69
300THM.
Top cooler line is the cooler return
line.
