Don't want to switch to a custom shifter? That's OK. The 6L80/6L90/8L90 will operate with any shifter. Just add our switch box to allow for tap up/tap down shifting. The switch can be mounted any place that's convenient for you.

Requires E38/T43 reprogramming for proper operation with 6L80/6L90 setups. Not compatible with E67 setups!

Requires our 8L90 Tap Shift CAN Relay for TapShift to work on Gen 5 swap using the 8L90 transmission.

Add pigtail? Select "Yes" if you're not using a Speartech powertrain harness with the Tap Shift plug built into the harness.
Pigtail is not necessary when using the tap shift switch box with an 8L90 transmission. Our 8L90 Tap Shift CAN Relay includes everything needed.

If using this for a Twist Machines Shrifter, you must select "Yes" to "For use with Twist Machines Shrifter" You do not need to select Yes to Add Pigtail!
