PPE 128041119 EPC BLOCKER FOR 11-19 GM 6.6L DURAMAX LML/L5P

This easy-to-install kit solves a big problem with the 2011-2019 Allison 1000 transmission... low mainline pressure.

Mainline pressure is created by the transmission's oil pump. Mainline pressure is directed by the valve body to the applied pistons and creates clamping force on the clutch packs, allowing the clutch packs to clamp quickly and completely. Reduced mainline pressure, or not having enough mainline pressure at the right time means reduced clamping force and there won't be enough to hold the torque of the engine. When clutch packs slip they generate excessive heat which destroys the clutch pack material.

The purpose of the EPC circuit is to modulate mainline pressure. Mainline pressure in a 2011-2019 Allison 1000 varies between 80psi to 230psi depending on driving conditions. When applying throttle to accelerate the mainline pressure will rise from 80psi up to 230psi. After the shift, the pressure drops back down to 80psi. At 80psi the clutch packs have barely enough clamping force hold the torque of the engine. The time it takes for the EPC circuit to close and allow the mainline pressure to build is too slow to effectively stop clutch plate slippage and premature wear. Installation of the EPC blocker allows the mainline pressure to be fully available at all driving conditions like the 2001 to 2010 Allison 1000 transmissions.

The EPC blocker kit quickly installs between the EPC solenoid and the valve body. There is no need to remove the valve body. Just drain the transmission fluid, remove the oil pan, and install the EPC blocker. Once installed, the EPC blocker will allow all the available mainline pressure, up to 230 psi, to reach the applied pistons and clutch packs at all times.

Features:

• Increase clamping force to clutch packs
• Improve shift quality
• Increase ability to hold more horsepower
• Easy to install
• Easy alternative to transmission line pressure tuning

VEHICLE FITMENT: 

The PPE 128041119 EPC Blocker is a vital solution FOR the FOR 11-19 GM 6.6L Duramax LML/L5P, specifically targeting the Allison 1000 transmission's mainline pressure issue. Ensuring your transmission operates at its peak performance, this kit tackles the troublesome low mainline pressure concern that can plague your vehicle.

By facilitating proper mainline pressure, the EPC Blocker prevents clutch packs from slipping, which can lead to excessive heat generation and damage to the transmission components. The stock EPC system is designed to regulate line pressure during shifts; however, FOR heavy-duty applications such as towing or aftermarket modifications, additional stress is exerted on the clutch packs, necessitating a more robust solution.

Easily installed between the EPC solenoid and the valve body without the need FOR complex removal processes, the EPC Blocker enables consistent mainline pressure delivery of up to 230psi to the clutch packs, ensuring optimal torque handling from the engine at all times. This user-friendly kit provides peace of mind FOR drivers seeking improved performance and longevity from their Allison 1000 transmission.

Choose the PPE 128041119 EPC Blocker FOR your FOR 11-19 GM 6.6L Duramax vehicle and experience the difference in transmission efficiency and durability. Trust in PPE Diesel to deliver reliable products that enhance your driving experience and keep your vehicle running smoothly FOR years to come.
