Product Overview
This premium AL4 / DPO Automatic Transmission Hydraulic Valve Body Assembly (OEM Part Number: 2570E3 / 2570.E3) is a fully calibrated hydraulic control unit engineered for PSA Peugeot Citroën and Renault 4-speed automatic gearboxes. As the primary hydraulic regulating unit, the valve body manages line pressure distribution, torque converter lockup, and clutch/band actuation. Due to fluid contamination or thermal fatigue, original AL4 valve bodies suffer from bore wear, stuck spool valves, and failing pressure regulation solenoids (EVM/EVR). This manifests as notorious AL4 fault symptoms, including sudden downshifts to 3rd gear limp mode, dashboard 'Gearbox Fault' warnings, severe engagement thuds when cold, and diagnostic codes such as Pressure Regulation Fault (Code 6 / P0841). Pre-tested and upgraded with durable pressure solenoids, this TRANSWIN 2570E3 valve body restores precise hydraulic response and smooth automatic gear shifting.
Product Specifications
- Transmission Model: AL4 / DPO (4-Speed Automatic)
- Product Name: Transmission Hydraulic Control Valve Body Assembly
- OEM / Reference Part Number: 2570E3 / 2570.E3 / 2570 E3

Key Features & Advantages
- Upgraded Pressure Solenoids: Equipped with high-reliability pressure control solenoids that eliminate the thermal drift and line pressure fluctuations common in original AL4 units.
- Precision Vacuum-Tested Bores: Internal valve bores are micro-polished and vacuum-tested to ensure zero internal cross-leakage and consistent pressure delivery.
- Direct Plug-and-Play Replacement: Pre-assembled to exact OEM dimensions and electrical resistance specs, enabling straightforward bolt-on installation without complex modifications.
- Eliminates Limp Home Mode: Solves common line pressure error codes and harsh cold-start 3rd-gear lockup faults.
