The ST-300 was also produced with a variable pitch torque converter. This converter could change stall RPM with an electric solenoid inside the transmission that was activated by a switch usually mounted on the throttle linkage. | The ST-300 was also produced with a variable pitch torque converter.

The proper matching Torque Converter will have the corresponding bushings inside the Torque Converter that creates the fluid channel. This fluid channel allows the pressurized transmission fluid to change the pitch of the vanes. |

| + | On the outside of this Torque Converter there are no tell tale signs to depict this converter as a switch pitch style converter. Some converters will have small welded bumps on the outside, yet in this case, this converter does not. Looking into the converter you will see 3 narrow bushings with about a 1/2 inch gap between two of them. This is indicative of being a switch-pitch style converter. | ||
