The OE pressure regulator valve design prevents adequate cooler flow at low rpm and high-pressure conditions, which can create overheating. Additionally, in 1999 and later vehicles, the factory EPC pressure was set high at idle, resulting in engine surge conditions in GM 4L80-E and 4L85-E units. Sonnax lube-regulated pressure regulator valves provide a significant increase in cooler flow under low rpm and high-pressure conditions that benefits all vehicles—and eliminates the need for reprogramming 1999 and later vehicles with high EPC pressure at idle.

Sonnax NSS adapter kits allow late-style, 5-wire neutral safety switch cases to be used in early-style, 3-wire vehicles. Chrysler changed the design of its digital neutral safety switch, the result was the case hole was made larger and the late-model Chrysler 42RE, 46RE, and 47RE cases could not be used for applications requiring the early-style neutral safety switch. Sonnax adapter kits screw into late-model cases, and when used with an earlier style valve body manual lever, allows these cases to be used in earlier model vehicles.

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.

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
