Product Overview

What this part is — and why it fails.

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.

Use Cases

Who orders this part, and why.

Code-driven repairs

P0750-series shift solenoid and pressure-control codes resolve predictably with a bench-checked solenoid.

Rebuild shops

Fit a full solenoid set during a rebuild and remove the age variable entirely.

Distributors

Solenoid packs for failure-leader platforms are small, high-turn stock.

Applications & Fitment

Buyer FAQ

Questions buyers actually ask.

Single solenoid or full set?

We supply both. For rebuilds the full set is common; for code-specific repairs a single verified unit is normal.

How are they verified?

Bench-checked for electrical response and hydraulic flow characteristics before packing.

Will it match my TCU calibration?

Solenoid families vary by generation — send your code and, where possible, the OE number stamped on the unit.

How do I verify this part matches my PSA / Renault unit before ordering?

Send the transmission code from the nameplate (or a photo of it). Our engineers confirm the generation and variant in writing before anything is packed — this removes the generation-mismatch risk that plagues this platform.

What are the ordering terms?

MOQ starts at one piece, lead time from 1 day for in-stock codes, 12-month quality guarantee across all product categories, export-grade packing with shipment photos.
