We Added an Evinrude 2 Stroke Oil Mix Chart for Your Convenience! Never any leaks from these either. Build with a torque converter lock, a 27-spline input/output shaft, 11-quart fuel capacity, a case length of about 27" and a width of about 19", and an aluminum outer casing, its torque capacity outdoes even the reliable 700R4 of the time. The constants in decoding the trans ID number are the date the transmission was produced. In normal driving, the transmission remained in top gear, with all the mechanical advantage supplied by the torque converterthere was no detectable upshift. What is the gear ratio of a 2 speed Powerglide? Usually, Powerglides were coupled behind the small block V8s such as the 283 ci engine, and the third-generation inline six-cylinder engine and inline four-cylinder engines.

The mark on the input shaft should have made 1 3/4 turns and be pointing to 9 oclock if it is a 1.76 ratio. $307.82. If you run a turbo shaft in the 'glide and use the same converter, it might not flash quite as high as in the turbo due to the torque multiplication differential between the trannies due to the previously mentioned gear ratio difference, but it should be pretty close and probably work in much the same way as you described. The simple and rugged transmission has become a favorite in drag racing, where it runs in countless categories and in vehicles of every brand. Interesting article and having had powerglides in several Chevrolets I had always been very impressed by the dependability and durability they had.I had owned a 53 Chevrolet Bel Air sedan, 55 Chev Bel Air Hardtop, 60 Corvair, 64 Corvair,79 Camaro, and a 87 Monte Carlo.Never any trouble with any of these.
