What transmission is this? Other than the Powerglide, GM doesn’t have a transmission with an adjustable band.


I’ll revise my statement, band adjust is made by using different length apply pins. The case is measured during initial manufacturing, and the proper pin is selected based on part production tolerance. Usually, you can replace the band and use the original servo pin and be fine. If major parts replacement is needed during a overhaul, you might need to change the apply pin to get everything back within limits.

It's an automatic out of a '51 Studebaker Champion, it was made by Borg Warner.

In fact, I think it was Borg Warner's first commercial automatic transmission.
