Has anyone ever changed a Saginaw trans extension bushing? This is
the bushing just ahead of the rear seal where the front u-joint slip
yoke fits into. If so, can it be done without disassembling the
trans. Should there be any play between the slip yoke and bushing?
Thanks, Clyde

If you have a leak at the extension seal that you could not stop with
a new seal and if the yoke is slightly loose, you probably have a worn
extension bushing. In order to stop the leak, you will have to
replace the bushing and seal, and the extension must be removed as the
bushing is removed and installed from the inside.

The bushing is GM 6260048, and since they come in a package of five,
find a dealer who has them in stock. It's a widely used part and has
a list price of less than $3 each. The rear seal for the Saginaw
four-speed is 3932255, which is not the same as the T-50 five-speed.

If you are a competent amateur mechanic and have a '74 Vega shop
manual with the Saginaw overhaul procedure, you could attempt the job,
however, you may be better off removing the trans and having it
overhauled by a competent transmission shop. The Sagninaw was widely
used, and the only unique part for the cosworth is the yellow
speedometer drive gear that was designed to mesh with the 23T and 25T
driven gears required for the high numerical axle ratios used on CVs.
