FAST Bump Stager trans-brake controllers provide improved staging accuracy by allowing you to access the patented "transcreep" function found in FAST XFI—without the added expense of converting your vehicle to a full XFI system. Drag racers, like yourself, will be able to carefully pulse the trans-brake, enabling your vehicle to move forward slowly during staging, creating a higher degree of repeatability than racers can achieve manually. The complete Bump Stager kits come with everything needed for use, and a built-in 20 amp driver removes the hassle of wiring an external relay for most applications. They can be used in carbureted applications or with any aftermarket EFI system. Improve your staging accuracy with FAST Bump Stager trans-brake controllers.

Transmission Specialties offers trans-brake solenoids for a variety of applications, including select GM Powerglide transmissions. These electric actuators are typically used in racing applications to engage and disengage a trans-brake in an automatic transmission. They essentially lock the transmission, allowing the engine to build full power without transmitting it to the wheels, which is crucial for controlled launches in drag racing. The replacement solenoids are engineered from factory materials and specifications to ensure proper fitment and performance.

Gain control over your transmission with an ATS Diesel Performance Co-Pilot automatic transmission controller kit. Street Co-Pilots are for people who want a transmission they can race on the weekends, but still drive on the street—without having to deal with overly-harsh shifts. With Street controllers, you get exactly that freedom. During everyday driving, the lower settings give you smooth shifts; while at the track, the higher settings give you full throttle shifting that is quick and crisp. All Co-Pilot transmission controllers give you control over your torque converter so you can bring it on faster or later depending on your driving style and preferences. Order the model recommended for your transmission application. Product features: * In-cab controls—you don't even need to pop the hood * Ability to raise line pressure on certain models * More effective than any "shift kit"—pressure increases more than double what shift kits do without harsh or erratic shifting * More efficient power transfer by controlling torque converter lockup; results in lower transmission temperatures * Adjustable on-the-fly * Street variants feature user-selectable race mode that forces lockup after the 1-2 shift while maintaining full line pressure * Automatically controls an exhaust brake on some models

American Powertrain reverse lockout modules are safety devices to save your transmission by preventing shifting into reverse on the freeway. These control solenoids communicate with the vehicle speed sensor in the transmission to let them know you are at zero mph so you can safely shift into reverse, rather than using a signal from the brake pedal.

Bowler Performance lock-up control modules come complete with everything needed to seamlessly control your torque converter lock-up. Converter lock-up will occur 8 to10 seconds after 4th gear engagement, allowing enough engine rpm gain before lock-up, giving your engine more performance and providing a better feel to lock-up. Bowler's lock-up modules only require one 2 amp fused 12 V wire to operate. No vacuum switch is necessary allowing these modules to function correctly with all types of engines, and there are no bulky boxes to hide or mount. The control modules have the GM 4-prong connector integrated onto the control board, and are epoxy coated to stay protected against the elements. Choose the kit designed for your transmission. Kits include: * Lock-up control module * Internal wiring harness with lock-up solenoid and mounting studs * Pressure switch * Pan gasket * New transmission filter * Case pass through connector * Brake light switch—standard that has a normally closed switch (for your lock-up module) and a normally open switch (for your brake lights). The brake switch does not have to be installed for the lock-up module to function, but will allow the driver to tap the brake to un-lock the converter at any time. If you are going up an incline and need a few more rpms to get up that hill, just tap the brake, and the lock-up will turn off and not re-engage for approximately 8 seconds. For those with a high-gear ratio and late down shifts who experience a chug of the motor due to the lock-up converter still being engaged; the switch will eliminate this concern.
