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.

Fewer moving parts means less possibility of failure and with many of the same great features of the higher priced shifters, you just cant go wrong! The Reverse lockout meets NHRA and IHRA requirements. Includes neutral safety switch, backup light switch, black T-Handle. Fits most popular 3-speed transmission applications.

Dont let the exceptional value fool you into thinking Tork Master Converters are not packed with lots of quality features, making them the best value-priced street performance converters money can buy. These converters perform best when paired with stock to modified engines up to 350hp/350 ft lbs. of torque, and lighter weight applications, like street rods. The Tork Master will provide noticeably quicker launches and harder acceleration while maintaining normal daily driving qualities. Upgrades like a new precision alloy steel pump drive tube, needle thrust bearing when factory equipped, new thrust washer between turbine and cover when required, and pressure tested and fully balanced by expertly trained technicians. Notes: Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. Not recommended for big block, supercharged, plate-type nitrous oxide or trans-brake applications.

The B&M Shift Improver kits feature two options to recalibrating your 1982-1993 GM TH700R4/4L60 automatic transmissions. First is the HEAVY DUTY set-up, giving you firm positive shifts without loss of driver comfort for improved performance in all street vehicles. This is a great option for performance street driving or towing. The second is our STREET/STRIP set-up. Be warned, this will deliver firm positive shifts you will feel, along with easily chirping the tires when shifting somewhat aggressively. This setting is recommend for high performance street/strip use, or for competitive events when you want the hardest, quickest shifts possible from a shift improver kit. Note: Does not fit GM TH4L60E (electronic) transmissions.
