  1. Powerglide, Minimize Leaks?

    Transmission and DriveLine Questions
    Help from original powerglide supporters, please. Someday I may "upgrade" to a modern overdrive cruis-a-matic, but not yet. Thanks. How much leaking is reasonable? How many miles should I expect before adding fluid? Is there hope to reduce leaks to minor drips? Drips and fluid stains in the...

Worked great, has sticker on starter says Arrow (?) not sure what that indicates. 25.00 and you pick...

    Transmission and DriveLine Questions
    I've got a 1956 Bel Air Sedan with a Powerglide. The transmission was working perfectly, but after an engine rebuild the trans started leaking, and later stopped shifting well.

  15. How can I tow a cast iron poweglide?

    Transmission and DriveLine Questions
    Hi, I want to tow a 56 Chevy with a cast iron Powerglide. I've heard that if you run the engine while your towing it, that will keep the front pump working and everything will be OK.

  17. 1955 Powerglide

    Transmission and DriveLine Questions
    Are all powerglide transmissions from 1955 the same? Will a transmission from a six cylinder car bolt up to a mid 60's 283 V-8? I'm thinking the V-8 uses a spacer or adaptor ring??? Thanks, Bill.
