Your cart is empty.Refill kit - Requires tool 124740-TL30 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 124740-30K restores normal switch operation, eliminating codes and providing renewed shift performance in all ranges. Allows salvage of expensive TEHCM NOTE: Before installing kit, test switches to verify proper electrical operation. Kit repairs laminate disc and seal failures only; it will not rectify electrical breakdown. See instructions for details.

It is the equivalent of oem if not better. Fixed my issue that I was having on my 6l80 transmission from my Escalade.

Worked great for my 6l80 2007 escalade. First hole i did i came out with a crease in it lucky i had extra ones. The best way for me was to insert them like if you had a bowl upside down & just go around pushing it down. Watch

Worked perfectly. If purchasing be sure to buy the installation tool kit. Can't say enough about Sonnax for coming up with this. Worked like a charm. Kudos....big time.

The tcm was priced at 896.00 at the local auto parts store. This kit fixed my tcm for pennies on the dollar

This really helped improve the shifting on my 2015 Chevrolet Impala Limited LTZ. I checked the RPO codes in the trunk of the car to verify that I had a Generation 1 6t70 transmission. The kit was relatively easy to install. It took the better part of an afternoon.
