Haltech Elite 2500 Supra Automatic Transmission Control A340

We are proud to offer a new update for the Automatic transmission Supra using the A340 trans. This new option moves all transmission control functions to the Haltech Elite 2500. This is the perfect option for anyone looking to add paddle shift functions or better control/tune a built automatic transmission. We do highly recommended using this option if you are looking to push the limits of the automatic trans. (Please note we also recommend adding the IO expansion module options with Automatic transmission control. This ensures you will have enough inputs/outputs for other aftermarket sensors/functions. This is not required for automatic cars, the normal harness leaves automatic trans control on the OEM ECU.
