Performance Shift Module

Product Description

The Performance shift module provides a simple and affordable method that allows switching your GM P01 or P59 ECU between shift tables while providing a visual indicator light when the alternative tables are active.  

NOTE: Before this device can be used the PCM must be configured to enable activation of the alternative shift tables using terminal 71 in the C1 PCM connector. Most operating systems used on the 99 - 2006 & 07 Classic engine computers are capable of having this option enabled, however you should verify your current PCM operating system does support this option prior to placing an order.
