8L90 Tap Shift & Reverse Light CAN Relay Kit
Our Price: $200.00

We have finally developed a solution to enable the tap shift and reverse light function when using an 8L90E in your swap project!

This CAN relay kit provides a +12V reverse light signal to your vehicle's back up lights. Works with 8L90E transmissions.

This CAN relay kit also provides Tap Shift support! Requires the use of our Tap Shift Switch Box to take advantage of this function.

Tap Shift is enabled when you shift into manual mode (M), which is one gear below drive (D). To exit manual mode, simply shift back up into drive and the transmission will resort back to regular automatic shifting conditions.

Note: Swap projects running a Camaro based tune calibration will only allow the Tap Shift function to operate while in regular drive mode (D). Just tap our Tap Shift Switch Box switch up or down, and you will be in manual mode. To exit manual mode, you must shift up to neutral and then back down to drive. The transmission will resort back to regular automatic shifting conditions.

Easy to wire in, every wire labeled, and comes with an instruction sheet.
