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.

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.

Z Automotive TranZformer electronic shift kits transform your car into a neck-snapping, tire-chirping fun to drive beast that at the press of a button, returns to stock. Best of all, they're completely hidden. Available in Gen 1 or Gen 2 kits, you can have your NAG1 transmission shift how YOU want it to. You get to modify shift firmness to fit your driving style/mood, plus a lot more. They install in minutes, connecting via wiretaps into wires hidden behind the steering column lower cover. Once installed, TranZformer kits will modify transmission parameters for that real "old school" muscle car shift feel. Chirp through gear shifts or just firm them up a little for towing or for track use; use your steering wheel buttons and EVIC screen (or cruise stalk/buttons for those without EVIC) to adjust shift firmness on-the-fly, whenever you want; connect to your PC via USB cable to dial-in independent upshift and downshift boost percentages (0 to 100) for each gear in both Drive and AutoStick mode. You can reduce the time delay when shifting into Reverse and Drive, adjust shift firmness scaling based on throttle position, and reset or kill the TCM's adaptive learning system, keeping the TCM from dialing back the shift firmness over time. Select the kit designed for your vehicle. Some of the features and benefits (may vary by kit): * Z Automotive Programming Utility (for Windows PCs only) allows you to program shift parameters, view status, update the firmware, and more * Steering wheel shifting (SWS) allows you to use your steering wheel's buttons to manually control gear shift while keeping your hands on the wheel * AutoUpshift allows you to set your own shift points when in AutoStick * Line Lock mode holds the vehicle with the front brakes so you can hit the gas and do a perfect burnout Peak rpm display: Will display actual shift rpms after each shift--great when adjusting auto upshift to squeeze every last bit out of that high revving cam, or to check what rpm you hit when shifting manually * 0 to 30 and 0 to 60 timer Reset adaptives: Will reset TCM adaptives any time you wish

BD Diesel TorqLoc systems will allow your torque converter to work at maximum efficiency. They feature three different converter settings. The manual setting allows you to manually lock up the converter. The stock setting transfers control of the converter lockup back to your vehicle's OEM computer. The AutoLoc setting locks up the converter when the exhaust brake is activated, allowing 100 percent of the retarding forces to be transferred to the rear wheels. This setting eliminates clutch slippage under heavy torque loads, reducing transmission temperature and extending transmission life in the process.
