The AL4 is the PSA / Renault (DPO) 4-speed automatic fitted to Peugeot 307, 408, Citroën C-Quatre, Elysée. This page covers the solenoid kit for that platform, supplied by Guangzhou Meishun (TRANSMESUN) — a CE-certified remanufacturing factory in Huadu, Guangzhou, with 20 years in the transmission trade.
One of the highest-volume units in Africa, the Middle East and South America: valve-body wear, solenoid regulation and thermal degradation are the classic failure chain. That failure chain is exactly what our process is built around: the part is inspected against the platform's documented wear points. Response and flow bench-checked per unit before packing. Every order is verified against your transmission code before anything ships.
