Product Details

If you're looking to get more control over your 2003-2005 Chevrolet Silverado 2500 HD's Allison transmission, especially when towing or in performance situations, the Fleece Performance TapShifter is a solid option. This unit lets you manually select gears using buttons, mimicking the functionality found in later model trucks and giving you a more direct connection to your drivetrain.

The TapShifter is designed to integrate with your existing Allison transmission, providing an improved shifting experience for various driving conditions, from daily commutes to more demanding towing or drag racing scenarios. It's a well-built unit that aims to make your truck more responsive and easier to manage when you need precise gear control. Installation involves tapping into your vehicle's wiring harness to enable the button-activated shifting.

This system is a popular choice for Duramax owners wanting to upgrade their transmission's control without a full rebuild. It offers a noticeable change in how you interact with your truck's power delivery.
