Purchase the PPE 128041119 EPC Solenoid Blocker today and address the significant issue of low mainline pressure in the 2011-2019 Allison 1000 transmission. This problem originates from the transmission's oil pump, which creates mainline pressure. The valve body directs this pressure to the applied pistons, ensuring the clutch packs clamp quickly and completely. However, reduced mainline pressure results in insufficient clamping force, causing slipping clutch packs to generate excessive heat and leading to clutch pack material damage.
To modulate line pressure, the stock EPC (electronic pressure control) is employed. During shifts, the transmission control module commands the EPC to adjust mainline pressure, which increases from 80 psi to 230 psi and then drops back to 80 psi after the shift. Unfortunately, at 80 psi, the clutch packs cannot withstand the engine's torque, especially when towing heavy loads or using aftermarket upgrades, putting more strain on the clutch packs.
The solution is the EPC blocker kit, which can be easily installed between the EPC solenoid and the valve body without removing the valve body itself. By draining the transmission fluid, removing the oil pan, and installing the EPC blocker, the kit ensures that all available mainline pressure, up to 230 psi, consistently reaches the applied pistons and clutch packs.
FEATURES:
- Increases clamping force to clutch packs
- Improves shift quality
- Enhances ability to hold more horsepower
- Easy to install
- Simple alternative to transmission line pressure tuning
Upgrade your Allison 1000 transmission with the PPE 128041119 EPC Solenoid Blocker for improved performance and reliability, especially under demanding conditions.
