With original Borg-Warner and Muncie four-speed transmissions becoming scarcer as time passes, GM enthusiasts are looking for other inexpensive four-speed transmission alternatives that can be easier to find without breaking the bank. The Saginaw four-speed fits that role nicely, and the additional gear can save you a little money at the pump as well. Saginaw four-speeds were manufactured from '86, and you can still find them in abundance at your local salvage yard or in many '60s, '70s and '80s donor cars. The four-speed transmission is very similar to the tried-and-true Saginaw three-speed and fits well behind six-cylinder and eight-cylinder engines. It was originally designed for engines generating less than hp; however, upgrade parts are available to make it more compatible with higher horsepower applications. Saginaw transmissions distinguish themselves from the Muncie four-speeds because the cases are cast iron rather than aluminum. Another quick way to determine a Saginaw is that the shifter arms are all located on the side cover of the transmission case Muncie reverse arms are located on the tailshaft. GM unit designations for the Saginaw four-speed are M26 or M For swapping into classic GM cars and trucks, we will only reference the rear-wheel-drive versions. You will find a donor Saginaw four-speed in one of these vehicles:. Installing the Saginaw four-speed in place of the three-speed is easy, because both transmissions use the same bellhousings. When converting from an automatic, you will have to locate a unit that has the correct bellhousing, foot pedals and shifter. Note that V-8 bellhousing bolt patterns are different for the Chevrolet than for the Buick, Olds, Pontiac and Cadillac.
