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 individuals 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 downshifts. Kit includes the instructions for a trouble-free and worry-free installation.
Note: Transmission does not need to be removed.
