2001-2010 GM 6.6L w/ Allison Transmission Duramax Valve Body Recalibration Kit
Even the venerable Allison transmission can use some well-placed improvements; that is why PPE has designed the Allison Valve Body Recalibration Kit (VBR kit).
The VBR kit is perfect for those individual who really punish their vehicles in activities such as towing, racing or extreme work. This kit corrects and reduces the Allison from going into neutral under a load. It also prevents 3rd to 4th gear slips, C2 or C3 clutch burning, and the tendency of sticking in one gear.
This kit allows customers to experience short, crisp and smooth up and down shifts.
Kit includes the instructions for a trouble-free and worry-free installation.
Note: Transmission does not need to be removed.
Kit includes gaskets and springs.
