Parts for your 2022 Haval H6-Transmission filter

2022 Haval H6 transmission filter: what’s fitted and what to service

Based on GWM/Haval technical literature for the 2022 H6 (including the 7‑speed wet DCT service information, the DHT hybrid transmission guide, and the AU/NZ Owner’s Manual maintenance schedule), there isn’t a separate, serviceable transmission filter element listed for routine maintenance. Parts catalogues for the 2022 H6 in Australia and New Zealand likewise don’t show a replaceable filter cartridge for the 7‑speed wet dual‑clutch or the hybrid DHT unit. In other words, a conventional transmission-filter isn’t used as a stand-alone service item on this model year H6.

Why that’s the case: the 7‑speed wet DCT in the petrol H6 and the dedicated hybrid transmission (DHT) in the H6 Hybrid rely on internal, non-serviceable strainers, fine mesh screens and sump magnets to catch wear particles. These filters are built into the transmission and only inspected or replaced if the unit is dismantled for repair. Because the mechatronics, clutch cooling circuits and valve body passages are tightly integrated, an external spin-on or drop‑in filter simply isn’t part of the design. GWM’s service schedules for the 2022 H6 reflect this by omitting any filter replacement task.

What owners should do instead is focus on fluid condition and operating temperature—because that’s what keeps those internal screens from being overwhelmed. While many dealers treat these boxes as “filled for life”, a preventive fluid change can be smart if the vehicle tows, sees lots of stop‑start, or works in hot climates. Use the specified GWM fluid (DCT fluid for the wet 7‑speed, the correct ATF for the DHT hybrid), follow the level‑setting temperature procedure, and always keep the fill and drain areas clean. If there’s shudder on take‑off, harsh shifts, metallic fuzz on the drain plug magnet, or burnt‑smelling oil, book a specialist inspection rather than chasing a non‑existent external filter.

• Stick to the factory maintenance schedule shown in the 2022 H6 Owner’s Manual for AU/NZ.
• Consider fluid changes at roughly 60,000–80,000 km if towing, driving in hilly terrain, or in frequent congestion.
• Use a workshop familiar with wet DCT/DHT filling and temperature calibration procedures.

If a transmission overhaul is ever required, the internal screens and magnets are addressed during that repair, which is the appropriate time to “service the filter” on this platform.

Popular questions

Does the 2022 Haval H6 have a replaceable transmission filter?
No. The 7‑speed wet DCT and the hybrid DHT used in the 2022 H6 use internal strainers and magnets rather than a serviceable external filter. The factory maintenance schedule doesn’t list a filter change item.

How often should the transmission fluid be changed on a 2022 Haval H6?
Follow the Owner’s Manual for normal service. If the vehicle tows, sees heavy traffic, or drives in hot conditions, many independent specialists recommend preventive fluid changes around 60,000–80,000 km using the correct GWM‑approved fluid and level‑setting procedure.

Can an external transmission filter be added to a 2022 Haval H6?
It’s not recommended. The lubrication and cooling circuits are designed around internal screens and precise pressures. Adding an external filter risks pressure drops and can affect clutch cooling or shift quality.
