Dorman SP609-008 Remanufactured Transmission Electro-Hydraulic Control Module TEHCM

The Dorman SP609-008 is a remanufactured Transmission Electro-Hydraulic Control Module (TEHCM) engineered as an OE FIX solution for select GM vehicles. This module has been fully tested and validated to match the function and performance of the original factory unit, while incorporating meaningful upgrades over the stock design to improve longevity and reliability.

As an aftermarket-exclusive design, the SP609-008 features upgraded PEEK (polyether ether ketone) plastic in place of the original material, providing significantly improved resistance to transmission heat and debris — two of the primary causes of TEHCM failure. Each unit is subjected to rigorous vehicle simulator testing prior to shipment and includes new gaskets, grommets, and seals to ensure a complete, ready-to-install repair.

Key Features:

• Remanufactured to OE specifications with upgraded PEEK plastic for enhanced heat and debris resistance
• Fully tested on vehicle simulators to validate function and performance before shipment
• Includes new gaskets, grommets, and seals — no separate hardware purchase required
• Direct-fit replacement for specified GM applications — no modifications needed
• More cost-effective alternative to dealership OEM replacement
• Limited Lifetime Warranty
• UPC: 889245900364

Programming Required: After installation, this module must be programmed using original manufacturer software to match the vehicle's VIN and configuration. Programming can be performed through a Remote Assist Programming (RAP) Kit or by a qualified dealer or shop with the appropriate scan tool. The module does not come pre-flashed.

Connector Details: Single rectangular connector | Male terminal type | 17-pin configuration

This TEHCM is a cost-effective, high-quality solution for addressing erratic shifting, transmission warning lights, or other symptoms associated with a failing electro-hydraulic control module.
