E-Transcontrol Announces New Controller for GM 4L and 5 L E Series Trannys



E-Transcontrol maker of the Magnashift line of electronics announces the release of its new 4th gen TCM820 controller for the GM 4L and 5L E series transmissions. This newest design incorporates all the best features of the previous TCM810 and TCM806 controllers and much more.

This new design includes a set of simple buttons on the box for easy setup and configuration, two new options for mounting the box and it can be custom ordered for under dash mount. The wiring harness and connectors are now broken out into two different connectors one for the transmission and a independent one for all the other connections. This makes for much easier wiring. It requires no PC for programming, so your time is not wasted trying to program your transmission to shift the way you want it to.

All Magnashift controllers are 100% manufactured and assembled in the USA including the internal circuit boards.

See our web site for more information and any accessories you will need for getting that project on the road.

Works with GM RWD 4L60E, 4L70E, 4L80E and 5L50E also works with GM FWD 4T45E, 4T60E, 4T65E and 4T80E transmissions.
