(B.Y.O.T) Bring Your Own 6L80/90 Transmission Solution includes the following:

Wanting to do a 6sp automatic trans swap in a 58x LS engine system vehicle and already sourced your transmission and programming solution? Just need a simple wiring harness solution? Then all you need is the TBM T42 Interface Module and harness.

This special is for those who bring their own transmission and have the correct model year transmission and programming, but don't want to spend weeks cutting and splicing wires.

NOTE: Minor calibration changes may still be necessary for acceptable driveability and performance. Consult your local professional tuner.

TBMSport's BRAND NEW GENERATION 3.0 T42-T43 Transmission Interface System consists of the core electronic components necessary to easily convert your E38/E67 LSx-V8 4L60-4L80 transmissions to a 6L80/90. This interface allows factory functionality of vehicles utilizing a E38/E67 Engine Control Module (ECM) and electronically controlled T42 Transmission Control Module (TCM) 4L60/65/70/80E to easily convert to a 6L80-90 transmission; without destroying your wiring harnesses. Only TBMSport will provide you with a Chevy/GMC Gen IV engine-transmission harness that allows you to use the latest transmissions (6L80E/90E) w/a simple pigtail harness swap. That gives you flexibility with your project's transmission options, peace of mind w/your harness purchasing decision, higher vehicle resale value, and ZERO harness removal/re-installation frustrations & losses. Requires reprogramming to ECM & T43 calibrations through programming modules like EFILive, HP Tuners, or GM MDI/Tech Tool. Visit our site for more information: www.TrueBlueMotorsport.com
