Product Overview

What this part is — and why it fails.

The 7DCT450 is the Great Wall Motor 7-speed wet dual-clutch fitted to Haval H6, GWM models. This page covers the switch, sensor & wiring for that platform, supplied by Guangzhou Meishun (TRANSMESUN) — a CE-certified remanufacturing factory in Huadu, Guangzhou, with 20 years in the transmission trade.

GWM's high-volume 7DCT; clutch packs, mechatronics and solenoids are the demand core. That failure chain is exactly what our process is built around: the part is inspected against the platform's documented wear points. Electrical function-checked per unit; connector and pin spec verified against the platform. Every order is verified against your transmission code before anything ships.

Use Cases

Who orders this part, and why.

Code-first diagnosis

Speed-sensor and pressure-switch codes often resolve with a €-level sensor instead of a teardown — diagnose electrical first.

Rebuild shops

Fit a new harness and conductor-plate gaskets during the rebuild; age kills connectors before gears.

Distributors

Sensors and switches are small, universal-turn stock across every platform you already carry.

Applications & Fitment

Which vehicles this platform serves.

Typical applications for this platform. Always confirm against the transmission code — one car line can carry two different units by year and market.

Buyer FAQ

Questions buyers actually ask.

Which sensor do I need?

By transmission code and sensor location (input/output speed, pressure, gear position). Send the code and connector photo if unsure.

Do you supply wiring harnesses?

Yes — internal and external harnesses for the major platforms are in the catalog.

Are pans supplied with gaskets?

Pans and pan-gasket sets are available; confirm with your code.

How do I verify this part matches my Great Wall Motor 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.
