1.Common fault symptoms: 1. Transmission shift shock (especially between 3rd and 4th gears or 4th and 5th gears) 2. Fault codes (e.g., P0716/P0717 input speed sensor fault, P2769 lock-up clutch control circuit fault) Diagnostic steps: Read fault codes: Use a diagnostic tool (e.g., GM MDI) to scan the TCM and confirm whether pressure switch-related faults are reported (e.g., P0841/P0842). Check electrical connections: Disconnect the TCM connector and inspect the pins for corrosion or loose connections (focus on power supply pins #1/#2 and sensor signal pins). Measure the TCM power supply voltage (standard value 12V) and ground resistance (should be <0.5Ω). Use an air gun (30 psi) to test the sealing of each pressure switch individually; if there is a leak, replace the diaphragm. Repair the pressure switch: TCM functions normally but individual switches are faulty (accounting for over 70% of 6T70 faults) Operational steps: Remove the TCM: Unscrew the 10mm mounting screws on the valve body, separate the TCM from the valve body, and ensure the manual valve aligns with the shift lever position. Replace the pressure switch diaphragm: Use a flathead screwdriver to pry out the damaged diaphragm and clean the switch housing. Seal test: Reinstall the rubber gasket and perform an air gun test (30 psi) to confirm no leaks. 2.Package size: 12.99 x 8.56 x 5.31 inches; package weight: 3.64 lbs. 3.OEM (Original Equipment Part) Number:42RLE, 5078327AA , RL078327AA. 4.Package List: 1 x 68RFE valve body assembly. 5.Fitment: Bu ic-k： Fits for Allure 2014-2015 3.6L Fits for Enclave 2008-2017 3.6L Fits for LaCrosse 2014-2016 3.6L Fits for Regal 2014-2017 2.0L Cadi lla-c： Fits for SRX 2013-2016 3.0L 3.6L Fits for XTS 2013-2019 3.6L Chev rol-et: Fits for Equinox 2008-2017 3.6L Fits for Impala 2012-2019 3.6L Fits for Malibu 2013-2015 2.0L Fits for Traverse 2009-2017 3.6L G-M C : Fits for Acadia 2007-2019 3.6L Fits for Terrain 2010-2017 3.6L Pon-tiac: Fits for G6 2007-2009 3.6L Fits for Torrent 2008-2009 3.6L Sa-turn: Fits for Aura 2007-2009 3.6L Fits for Outlook 2007-2009 3.6L Fits for Vue 2008-2010 2.4L 3.5L
