Abstract: An automatic transmission is adjusted by changing the longitudinal position of a pin relative to a hydraulically-actuated piston, the pin being threaded into the piston. A holding socket engages the piston and prevents it from rotating while the pin is being adjusted. The holding socket engages a support guide which is contained within the transmission casing.
