Description
Overview
Improve your Allison transmission shift firmness with the PPE Pressure Calibration Kit. This kit allows you to achieve your desired shift firmness based on the spring selection you choose to install. The PPE Pressure Calibration Kit sets minimum pressure and boosted pressure levels that are adjustable within in the kit. This kit serves as a great upgrade when building a Allison transmission. The increase in line pressure improves your clutches’ holding ability and the calibration springs will tighten up shifts. Select between the 450-800hp or the 800hp plus kit depending on the power level of your truck.
