Parts for your 2020 Haval H6-Transmission filter

2020 Haval H6 transmission filter — what’s fitted and how to look after it

Based on GWM/Haval’s 2020 H6 Owner’s Manual maintenance schedule, the factory 7‑speed wet dual‑clutch transmission (7DCT) fitted to most AU/NZ‑spec 2020 H6 models uses a serviceable transmission oil filter. This is echoed in GWM 7DCT workshop procedures and parts catalogues that list a replaceable DCT oil filter element for the H6. Manual‑gearbox variants don’t use an automatic/DCT transmission filter, but the vast majority of local 2020 H6 vehicles are 7DCT and therefore do.

On the 2020 Haval H6 7DCT, the transmission filter’s job is to keep the transmission fluid clean as it circulates through the clutch cooling and hydraulic control circuits. By trapping clutch material, fine metal and other contaminants, the filter protects the mechatronics unit, solenoids and valve body from abrasive wear and sticky deposits. Clean fluid and good filtration help the DCT shift smoothly, keep clutch temperatures under control, and extend the life of seals and bearings.

For servicing, Haval’s technical literature specifies periodic replacement of the DCT fluid and filter. In normal use, workshops typically see the interval land around 60,000 km or 4 years (whichever comes first), vehicles that tow, sit in heavy traffic, or drive in hot, hilly conditions may need earlier service. Always check the vehicle’s handbook or dealer service data for the exact interval that applies to the VIN.

Best practice is to replace the filter whenever the DCT fluid is renewed. Technicians will drain the fluid at the specified temperature, replace the filter element and O‑rings, refill with the correct GWM‑approved DCT fluid (not generic ATF), then complete the temperature‑guided level set and adaptation/learn procedures with a scan tool. Skipping the filter can leave old debris circulating in fresh fluid and undermine the service.

• Use genuine or OEM‑equivalent filter and seals.
• Confirm fill level at the procedure’s target fluid temperature.
• Inspect for leaks, worn mounts and wiring to the mechatronics.
• Watch for warning signs between services: harsh or delayed shifts, shudder, overheat messages, or metallic glitter in drained oil.

Kept on schedule, the H6’s transmission filter is cheap insurance against costly mechatronic or clutch repairs, helping the DCT deliver the smooth, efficient drive owners expect.

Popular questions

Does the 2020 Haval H6 have a transmission filter?
Yes—on models with the 7‑speed wet DCT, there’s a serviceable transmission oil filter. Manual‑gearbox versions don’t use an auto/DCT filter.

How often should the H6’s transmission filter be replaced?
Common practice is around 60,000 km or 4 years with the DCT fluid, sooner for heavy use. Always confirm the exact interval in the H6 handbook or dealer service data for your VIN and market.

Can any workshop replace the H6 DCT filter, or does it need a dealer?
Any competent transmission or European‑style DCT workshop can do it, provided they use the correct GWM‑approved DCT fluid, follow the temperature‑based level set, and perform adaptation with a scan tool. Dealers will have the latest procedures and software if updates are needed.
