Powerglide Transmission Handbook: How To Rebuild or Modify Chevrolet's Powerglide for all Applications
Starting in 1962 all the way through 1972, Chevrolet manufactured a staggering 17 million aluminum Powerglide transmissions.
In spite of the huge production numbers, the Powerglide was not considered a performance tranny, but became the dominant automatic tranmission in modern motorsports all the same.
Chevy's Powerglide is the auto trans of choice for circle track and drag racers alike, and you will find Powerglides installed in a wide variety of vehicles, from street to strip to Top Sportsman.
In this book, author Carl H. Munroe, provides a detailed and comprehensive reference guide to the Powerglide, ranging from a factory-stock rebuild to an all-out race transmission.
SUBJECTS COVERED INCLUDE:
- General Transmission Service, Basic Operation, In-Car Service and Repairs.
- Torque Converter Design and Operation.
- Removal, Disassembly and Inspection.
- Final Assembly of Transmission.
- The Drag Racing Powerglide.
- The Circle Track Racing Powerglide.
- Specifications and Troubleshooting.
Book Excerpt: Powerglide Transmission Handbook: How To Rebuild or Modify Chevrolet's Powerglide for all Applications
One of the most important aspects of automatic transmission repair is cleanliness. Before any disassembly is attempted, the outside of the case should be thoroughly cleaned.
This can be accomplished by steam cleaning, pressure washing, or using a solvent. Scrapers and a wire brush are handy tools to remove thirty years of built up grease and crud found on more cores.
Many do-it-yourself car washes have engine cleaning solvent sprays that are ideal for this purpose.
All parts removed should be cleaned with cleaning solvent and dried with compressed air. If a cleaning tank is not available, a spray brake cleaner, although more expensive, will work equally well.
Paper wipers or shop rags should never by used to dry internal transmission parts. Wipers and rags can leave lint on parts that can cause problems at a later date.
Also, be aware that some solvents (such as certain carburetor cleaners) can damage rubber seals and clutch facings.
Begin the disassembly by draining any remaining fluid from the pan. You will need a sturdy workbench and a clean area to arrange your parts.
There are several tools and fixtures that can be made from scrap materials that will make this project much easier. Thankfully, the Powerglide requires very little in the way of specialized tools.
The most exotic tool required is a dial indicator with a magnetic or clamp base. Everything else is a basic hand tool or can be fabricated. Refer to Chapter 5, Specialty Tools for the Powerglide.
It should be noted that an air/electric ratchet or 3/8" drive impact gun can be used for disassembly. Do not however, use power tools when assembling the transmission.
There are several things to keep in mind as you tear down the transmission: Save everything you remove.
Even though you will be discarding many components later, it is a good practice to save all gaskets, seals, clutches and steels for comparison to the replacement components.
If this is the first Powerglide you have worked on, or if you have trouble remembering where things go, keep all related components in sandwich bags, coffee cans or other containers.
For example, when you remove the pan bolts, they could be placed in a sandwich bag with a tag identifying what they are.
It is also a good idea to check the end play of the transmission before you disassemble the unit. By checking the end play ahead of time, you will know if you need to replace, or shim, the thrust washer at final assembly.
