For many people in colder climates, getting ready for winter is a major task that can require months of work. A lot of us have just gotten used to the routine and, in some cases, have had our jobs made easier.

This is certainly true of transmissions, and it’s easy enough to see how many of the old ways of “winterizing” are no longer applicable to modern automatics. That being said, there are still a number of things that you can do in order to prevent something from going wrong on the road. While some of these require expensive tools that only mechanics tend to have, there’s quite a bit that you can do on your own to at least make the process easier. Continue reading…

Why You Should Carry Spare Powerglide Transmissions for Your Chevy II Race Car

Posted by on Tuesday, October 21st, 2014

The Powerglide is a two-speed automatic transmission designed and built by General Motors. It was one of the first automatic transmissions and a great alternative to the manual transmissions of the period. GM built the first Powerglide transmissions (turboglides) in the 1950s. They made them of heavy cast iron and with different driving characteristics than later model Powerglides. The Powerglide that most people are familiar with was first produced in 1962. Besides operating slightly differently, the main change was that the transmission was made of lightweight, but very strong aluminum. This new model Powerglide transmission also came in a heavy duty version for use behind the powerful 409 big block engines. GM used the Powerglide in just about every model they produced at that time, including the C10 truck, the Impala, the Chevelle, the GTO, the Camaro, the Firebird, the Vega and the Pontiac Ventura. Gm also used the Powerglide in the Chevy II.

Transmission fluids

Everybody wants to save money and effort, and in many cases that materializes in a willingness to try cheap or easy solutions to problems rather than going to a professional who has the tools and training to get the job done right. Perhaps the most obvious and problematic version of this is the use of transmission fluid additives designed to fix leaks or other, similar issues. While this might seem like a good idea, it can ultimately lead to transmission failure. Continue reading…

Protect the 700R4 Transmission in Your Chevy Ice Cream Van

Posted by on Thursday, October 16th, 2014

The 700R4 is one of the very first automatic overdrive transmission built by any of the big three auto makers. It is heavily related to the 4L60E family of transmissions but doesn’t make use of extensive electronics. It has a very nice 3.06:1 first gear ratio, which helps contribute to better off the line takeoff. It also uses a generous 0.7:1 overdrive gear ratio that greatly improves gas mileage and drivability. Early 700R4s were very problematic, which is to be expected with new technology. As time went on, General Motors made many improvements to the 700R4 that made it a favorite with consumers. The first 700R4 automatic transmissions were produced in 1982 as a response to the government’s attempt to force car producers to increase gas mileage. GM used the 700R4 in a wide variety of their vehicles, including the Chevy Corvette, the Camaro, the Trans Am, the Blazer, the S-15 Jimmy and the Chevrolet C/K pickup trucks. GM also used it in the Chevy full-size van.
