B&M's ShiftPlus electronic shift improvers use vacuums or electronics to improve the characteristics of your transmission, and let you change settings as you drive. Great for performance, towing, and RV use, these shift improvers recalibrate your transmission in one of two ways: Vacuum-style transmissions, such as a GM 4T60E, simply recalibrate the hydraulic system through the modulator circuit to provide firmer, more positive shifts; electronically controlled transmissions, such as a Ford AODE, recalibrate the transmission's hydraulic system electronically to give you a firmer, quicker shift, for better performance and longer transmission life. A flip of the switch allows the transmission to operate in the original factory mode at level 1 (firmer than factory) or level 2 (much firmer than factory). Either type installs in minutes with a few simple hand tools, without removing the pan.

TransGo automatic transmission reprogramming kits are designed with performance in mind. Most, but not all models contain additional features like Gear Command that allows you to hold manual low to any speed, and shift back to low at any speed. They are great for strip cars or 4x4 rock crawlers needing to select low and not have it upshift. Most TransGo automatic transmission reprogramming kits can be tuned for HD (Heavy Duty) use by following the recommendations in the kits.

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

You'll have a heavy-duty, reliable transducer when you install BD Diesel valve body electronics upgrade kits. One of the leading causes of faults with automatic transmissions is failed governor pressure transducers, especially if you run higher line pressures. These kits replace the stock plastic transducer with a sturdy metal unit that can handle greater line pressures without failing; preventing over-pressure codes and wild oscillations, thus extending transmission life.

The locker sensor in Wrangler JL and Gladiator Rubicons have started to become problematic. When they fail, it usually starts out as a blinking locker indicator on the dash, which then ends up in a "service axle locker" message and the lockers will no longer engage. The repair would normally be to replace the sensor or the locker assembly, but they are not available, so the entire axle assembly needs replaced. Developed in a partnership with Americas Most Wanted 4X4, Z Automotive Jeep JL/JT Z-Locker OEM controller harnesses provide a simple fix for faulty OEM axle locker. Each harness will bypass the problematic sensor, allowing the locker to operate without the position sensor and provide the proper feedback to the Jeep's computers to keep the system operational without any errors or warnings. You get fully functioning lockers with no side effects. Installation is simple and they will not harm the Jeep's computers as they use the same signaling that it expects from the sensor. The connectors are the same ones used by Jeep and are watertight.

ACT race clutch discs are available in three distinct styles--choose the options that best suit your application. Spring-centered discs are the most popular and feature reduced driveline shock and spline wear with quieter operation. Rigid-hub versions offer improved durability but increase gear noise and spline wear. For either of those hub designs, you can choose six pads for better heat management and engagement, or four pads for the quickest shifting. Sintered iron discs offer the highest torque capacity and ultra-high heat capacity. They're designed for cars using clutch-less shifting or drag racing transmissions. Additional product details: * Premium ceramic friction materials provide high-heat tolerance, high coefficient of friction, and low wear rates * Carefully broached splines provide exact fit onto the transmission input shaft for long spline life and better clutch release * Heavy-duty torsional dampening springs are provided in the best sizes and spring rates to help reduce noise * Drive plates are made of high-carbon steel; heat-treated and black zinc coated to resist bending, cracking, fatigue, and rusting * Certified to SFI specifications
