Send Us Your T43 TCM
Place your T43 TCM in a box, and ship it to us (using any shipping method). You may choose from two programming options, from the dropdown menu.
Speed Only - adjust the gear ratio, tire size, and transmission shift points, to be compatible with your project vehicle.
TUTD Enable - this option includes all of the features of the Speed Only option listed above. We will also enable the Tap Shift feature to operate via a single wire (hardwire) input. Tap Shift is sometimes referred to as Tap-Up-Tap-Down (TUTD). Only Corvette T43 TCM calibrations have Tap Shift enabled by default.
*** to operate the Tap Shift function in your project vehicle, requires the use of a Tap Shift Switch (sold separately) ***
*** the T43 TCM is bolted to the transmission valve body - we only need the TCM for programming (do not send the valve body) ***
These TCMs were used in many 2006 to 2018 vehicles equipped with a 6-speed automatic transmission (6L80E / 6L90E).
