6L80, 6L90 Pressure Switch Rebuild Kit 2006-up

Listed GM 6-speed transmissions often set various trouble codes related to failures of fluid pressure switches that are internal to the transmission electro-hydraulic control module (TEHCM). These codes may be accompanied by TCC apply problems or shift irregularities such as slipping, flares, harsh application, and bind-ups. As time goes by, the laminated portions of the pressure switches can breach, preventing normal switch operation. If more than one switch breaks down, failsafe mode can be triggered. Since switches cannot be obtained through OE channels, replacement of the TEHCM was the only previous remedy available.

It is no longer necessary to replace the expensive TEHCM assembly to rectify this concern. Installing Sonnax pressure switch rebuild kit 124740-70K restores normal switch operation, eliminating codes and providing renewed shift performance in all ranges.

  • Allows salvage of expensive TEHCM
  • Kit includes enough discs and seals to rebuild 1 TEHCM units
  • MTSW Recommends Pulling all these out of Techm to clean the metal caused by the Torque Converter Lockup Plate grinding the converter cover every time the Lockup Plate is applied. This requires Tool 124740-TL70.
