Parts for your 2019 Haval H6-Transmission filter

2019 Haval H6 transmission filter — what it does and when to replace it

Based on technical literature for the model years around 2019, the 2019 Haval H6 does use a transmission filter. Haval/Great Wall Motors workshop documentation for the 7‑speed wet dual‑clutch transmission (7DCT) includes a dedicated “oil filter replacement” procedure, and the MY2019 maintenance schedule references DCT fluid and filter service. The Great Wall Motors electronic parts catalogue also lists a replaceable DCT oil filter element for the H6. For vehicles fitted with the 6‑speed automatic (Aisin) in some markets, an internal strainer is used, it provides filtration but isn’t typically serviced on its own. These details are consistent with supplier technical briefs for wet‑clutch DCT systems (e.g., BorgWarner hydraulic modules) that specify pressure/suction filtration for clutch and mechatronic protection.

On the 2019 Haval H6, the transmission filter’s main job is to keep the fluid clean by trapping clutch material, fine metal and general wear debris. In the wet‑clutch 7DCT, clean fluid is critical: it cools and lubricates the clutch packs and feeds the mechatronics that control shift timing and line pressure. A healthy filter helps maintain smooth shifts, consistent take‑off, and protects expensive components from abrasion and varnish build‑up. Even where a 6‑speed auto is fitted, filtration matters for valve‑body health and torque‑converter longevity.

For routine servicing, owners should plan the filter alongside the fluid. A practical guide many workshops follow is replacement around 60,000 km (or 4 years), sooner if the vehicle tows, sees hot Aussie or Kiwi summers, or does lots of urban stop‑start. Always use the Haval‑approved DCTF/ATF and a quality filter element with new O‑rings or seals. On the 7DCT, correct fluid temperature and level setting are essential, many shops use a scan tool to monitor temperature and may perform clutch/shift adaptations after the service. If an Aisin 6‑speed is fitted, the internal strainer is normally inspected or replaced only when the pan is off for other work or during a rebuild.

• Watch for tell‑tales like harsh or lazy shifts, shudder, burnt‑smelling fluid or overheating warnings, these warrant a filter and fluid check.
• Stick to clean practices: any dirt introduced during a change defeats the purpose of a new filter.
• If in doubt about transmission type (7DCT vs 6AT), check the build plate or a dealer service portal before ordering parts.

FAQs

Does a 2019 Haval H6 have a transmission filter?
Yes. H6 models with the 7‑speed wet DCT have a serviceable transmission oil filter. Variants with the 6‑speed automatic use an internal strainer, it provides filtration but isn’t typically replaced as a standalone service item.

How often should the H6 transmission filter be replaced?
For the 7DCT, many service schedules and workshop practices target roughly every 60,000 km or 4 years. Shorten the interval if the vehicle tows, drives in high heat, or lives in heavy traffic. The 6‑speed auto’s internal strainer is usually addressed only when the pan is removed or during more extensive transmission work.

Can this job be done at home?
It’s possible for experienced DIYers, but the 7DCT needs the correct fluid spec, precise temperature‑based level setting, and clean handling. A scan tool is recommended, and some procedures include adaptation resets. Most owners will be better off using a transmission specialist.
