This type of sensor may fail to function under hostile conditions or simply wear over time. When that happens, help keep your drivetrain running optimally with the Sonnax primary and secondary pressure sensors designed for your application.

Holley Sniper Automatic Transmission Controllers
The Holley Sniper Transmission Controller (STC) is designed for common GM and Ford electronic 4-speed automatic transmissions. Three part numbers cover a complete range of applications—all Sniper EFI systems, Sniper 2 EFI-specific (M8 CAN connection), or a full standalone unit. The Sniper specific applications connect to your Sniper EFI system via CAN bus and are programmed through the existing Sniper 3.5 in. touch screen. No programming is available with PC computer software; however, the transmission functions can be data-logged and reviewed with Sniper PC software. The Standalone version includes a dedicated 3.5 in. touch screen and is primarily intended for carbureted engine combinations. GM and Ford 4-speed electronic overdrive transmissions are simple in operation. They have four speeds, with the top gear being an overdrive; and all have a lockup torque converter that eliminates any slippage when the lockup is applied. With a stock torque converter, the lockup should only be applied under light throttle conditions or excessive wear will occur. Upshifts, downshifts, and torque converter lockup are based on vehicle speed and throttle position (or optionally the MAP sensor) and are adjustable with the 3.5 in. touch screen. P/N 551-100: Replacement controller unit only P/N 551-101: Controller unit and power harness only P/N 551-102: Standalone kit for carbureted applications (includes power harness and hand-held programmer) P/N 551-103: Controller unit and power harness for use with Sniper 2 EFI systems Holley Sniper Transmission Controller features: * Adds electronic transmission control functionality to a Sniper 2 * Controls conventional electronic 4-speed transmission applications.

Bowler Performance All-in-One Transmission Wiring Harnesses
Bowler Performance All-in-One transmission wiring harnesses for the Tremec T-56 Magnum transmission comes equipped with all the connections pre-wired into one harness for a simple installation and ease of use. The small epoxy sealed controller is mounted to the VSS output using the existing bolt, and once the unit is powered up, you will be able to connect via Bluetooth to your Apple or Android smartphone using Bowler's free app. The app will give you the ability to customize the input and output settings for each feature to ensure proper operation in your vehicle. The perfect finishing touch for any Tremec T-56 Magnum conversion, Bowler's All-in-One harnesses eliminate the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your Tremec T-56 Magnum. Previously, you would have needed up to five separate parts to perform all the same functions wrapped one of these harnesses. The more technology we incorporate into our hot rods sometimes requires specific input signals to allow everything to function correctly. With the two speed outputs available in these harnesses, you can independently control the output of each one further eliminating any need for additional equipment and connections. Regarding the reverse lockout, Bowler has incorporated the same speed setting feature as the OEs into the All-in-One harnesses, giving you better control over when the lock out is triggered. Bowler's All-in-One harnesses give you much greater flexibility in the components you are able to use and require less time wiring everything up, providing an easier solution for setting up your Tremec T-56 Magnum transmission. Choose the harness version designed for your specific transmission make. Additional notes: * Harnesses utilize a small, built in, epoxy sealed box that will control each of the three functions with power and grounding for each function through a switched +12 V circuit and a wire connected to the negative battery post or engine block. * Control of the reverse lockout solenoid is based on a user defined speed setting (default is set at locked above 4 mph and unlocked at 0 to 3 mph), eliminating the need for a separate lock-out control box. * For your electronic speedometer, the harness is equipped with two speed sensor outputs; the speed sensor outputs generate a square wave signal that goes from about -5 to roughly +5 V, varying in frequency as the speed changes. * Output will automatically shift and give you 0 to +10 volts for EMC input needing positive only signal. * The two speed sensor outputs are completely independent and can be calibrated separately with any pulse count and ratio you want, and are able to drive any common speedometer, cruise control, or ECM. * Tremec T-56 Magnum reverse lock-out module VSS with dual output, pre-set as GM 40-pulse output on one and 16-pulse output on the other and can be adjusted with your iOS or Android device. * Includes wiring for reverse lights, reverse lock-out, and vehicle speed sensor.

Reid Racing Super Hydra 400 Transmission Cases
Redesigned and strengthened, Reid Racing Super Hydra 400 transmission cases address weaknesses and add features that improve every aspect of the Turbo 400. They build their Super Hydra 400 cases with full 360 degree internal case "lugs" that retain the center support and pressure plate. Not only are they lightweight and offer minimal drag, but their abuse tolerance has been kicked up several notches to handle high-horsepower levels without ending up with a ruined transmission! A direct replacement for the GM case, Reid cases use an incredibly expensive permanent mold casting technique to increase the case wall thickness, making it sufficient to pass SFI 4.1 certifications without the need for any external shields or internal liners. Super Hydra 400s are massively tough, ductile, and leak-free—with the strength to handle rock crawling, as well as desert or short-course truck racing. Their modular, 2-piece design allows them to be used with all popular engines by simply changing bolt-on Superglide bellhousings. Reid Racing Super Hydra 400 transmission cases are offered in drag/street and off-road versions, each with features geared specifically for those applications. Features: * Speedometer and governor provisions * Improved billet steel pressure plate * Oversized snap ring * Longer band anchor pins captured by oversize bosses * Additional dipstick hole on driver side * Multiple external pressure taps allow for monitoring of circuit pressures * Accept all style oil pumps, including 8-bolt and vari-pitch designs * Heli-coiled bellhousing and oil pump threads * Pre-machined to fit larger custom planetary gear carriers Off-road also includes: * Pre-machined side oil feed feature for 4L80-E center support * Front band anchor tapped for custom ARP anchor bolt (supplied) * Pre-machined bosses for input and output speed sensors * Un-machined speedometer boss for maximized 4x4 transfer case load support * Oil line ports machined for -AN fittings * Pre-machined with additional stud/nut clearance for Advance Adapters transfer case adapters * Available with a 4L80-E size pressure plate

Z Automotive Jeep JL/JT Z-Locker OEM Controller Harnesses
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.
