MSD Atomic Transmission Control Modules
MSD Atomic transmission control modules are designed to adjust the operating parameters of later model electronically controlled 4-speed automatic overdrive transmissions. They're simple to configure with the supplied hand-held monitor--no PC required. You now have access to adjust shift points, adjust torque converter clutch behavior, select different levels of shift firmness, select between auto-shift and manual shift mode, and activate dyno mode to deliver repeatable chassis dyno results. The included hand-held monitor connects to them and can be left in place as a dashboard to monitor the transmission in real time, or can be disconnected when the configuration is complete. Once installed, these modules need only a few basic parameters to complete the initial setup. First, select the type of transmission you are using--all supported transmission types are listed in the menu. Other required fields include the number of engine cylinders, rear-end gear ratio, and tire height. Once this has been completed, you can now start and drive the vehicle, while taking advantage of the advanced setup menu items to dial-in the transmission to your liking. You can feel the results in real-time as a passenger manipulates the parameters and monitors the real-time data. Data available for viewing includes engine speed, vehicle speed, throttle position, transmission fluid temperature, shifter position, and commanded gear. Best of all, the MSD Atomic transmission control modules are available as completely stand-alone units or Brainwave-compatible for the Atomic EFI systems. A transmission controller harness is sold separately.

Sonnax Automatic Transmission Electro-Hydraulic Control Modules
The GM 6L80 and 6L90 TEHCM houses the transmission control module (TCM), or computer. The eight solenoids are connected to the TCM via a lead frame, all of which are over-molded in the plastic housing and not accessible or serviceable separately. Component fails and circuit faults in the GM 6L80 and 6L90 TEHCM are common, and result in drivability complaints and trouble codes which can only be remedied with a replacement unit. These automatic transmission electro-hydraulic control modules by Sonnax serve as a durable, reliable OE performance solution at a significant savings over OE replacement. Each Sonnax TEHCM GM6L-TEHCM-C6 unit goes through a rigorous cleaning and inspection process where all failed components are replaced. Electro-hydraulic testing in a simulated drive test ensures full functional performance consistent with a new OE TEHCM. A vehicle VIN remains on the Sonnax remanufactured TEHCM and will be overwritten by a transmission shop technician with the new vehicle VIN during the reprogramming process. After installation, the TEHCM must be reprogrammed on the vehicle using a J2534 device in order to function correctly. The fully tested TEHCM is serialized, and the test data stored and packaged in Mylar bag with a protective connector cover to prevent inadvertent static discharge issues during the shipping, handling and receiving processes. Part information details: * Ultrasonically cleaned and thorough flushing of solenoids to remove all dirt and debris—no matter how hidden * New pressure switches installed * New filter plate/screen included * Fully electro-hydraulically tested to comply with OE performance * Must be reprogrammed after installation using a J2534 device for proper function

Classic Instruments Tap Shift Switch Modules
Classic Instruments tap shift switch modules are aftermarket control boxes that add manual "tap shift" control (upshift/downshift with a switch) to modern GM 6L80, 8L90, and 10L90 automatic transmissions, enabling them for engine swaps into older vehicles. The modules wire into the CANbus system and require a compatible GM ECM/TCM tune, providing features like a neutral safety switch and reverse light output for custom setups. In short, these are a translator box for your engine's computer, letting you control your modern automatic transmission manually in a custom project. What the product does: * Adds tap shift: Allows you to manually change gears (up/down) using small toggle or micro-switches instead of a factory shifter * Adapts transmissions: Bridges the gap for using modern computer-controlled GM transmissions (like 6L80/8L90/10L90) in classic cars or custom builds * Provides safety features: Includes a ground output for a starter relay (preventing starting in gear) and an optional negative (-) signal for reverse lights/backup cameras Key requirements: * Compatible GM TCM/ECM: Needs a proper tune (often a Corvette or Camaro tune) for the module to function, as it communicates via the vehicle's CANbus * No DTCs: No Diagnostic Trouble Codes should be present in the ECM/TCM for tap shift to work * Switch inputs: Supports various inputs, typically "pull-to-ground" or "positive-pull-to-12 V" switches, with negative being preferred

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.
