Real-World How-To: Make the Most of TapShifter

  • Mountain towing: Lock out OD and select a lower gear before the grade starts; use lock-up control (5R110) to keep temps in check.
  • Curvy backroads: Limit the top gear to prevent hunting; throttle response sharpens because you’re in the right ratio.
  • Dyno or racing: Manual upshifts let you hold power where it counts; lock-up control improves repeatability.
  • Pair with braking: 6.0L kit’s integrated VGT brake control adds serious downhill confidence; Allison/6.4L pair great with BD exhaust brakes.

FAQ

Do I need tuning?
No. These are designed to integrate with factory control modules using plug-in harnessing.

Will TapShifter hurt my transmission?
Used correctly, it reduces heat and hunting by keeping the gearbox where it belongs. Always monitor temps when towing heavy.

What about converter lock-up control?
On 5R110 kits, lock-up is available in 4th/5th. It’s ideal for grade holding and dyno consistency.

Anything to watch during tuning/flash?
Disconnect the TapShifter OBD lead before ECM/TCM programming to avoid conflicts (6.4L kit note).
