NOTES:
- Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you a higher stall speed, less torque at 2,500 rpm will give you a lower stall speed than the stall speed ratings indicated.
- Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler.

- This converter is NOT recommended for supercharged, plate-type Nitrous oxide or trans-brake equipped applications.

Overview

This Holeshot 3200 fits 1965-91 GM TH400, 425, 375 and 1968-81 TH350, 375B (not 350C) transmissions. Holeshot torque converters are for serious-minded performance enthusiasts and offer additional strength and durability features not found in our Tork Master or Traveler series of converters. The Holeshot 2400 converter is an excellent choice for vehicles with some performance engine modifications, particularly big cams that tend to reduce low-end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Holeshot converters feature furnace brazed impeller fins and turbine, new precision alloy impeller hub and new heavy duty needle bearings.

If your vehicle is equipped with a plate type nitrous system or supercharger, please refer to the Nitrous Holeshot line of torque converters.
