Quick answer
Haval UAE describes the H6 GT gearbox as a second-generation 7-speed wet dual-clutch transmission (7DCT) with a low-leakage hydraulic control system, and the 2025 sheet lists 4WD. Because the clutches run in fluid, the H6 GT needs the wet-DCT fluid Haval specifies, not ordinary ATF. The 4x4 driveline adds units with their own oils. ShipMyPart has not verified any fluid specification, quantity or interval, so we confirm by VIN before supplying fluid.

Reading Haval’s gearbox description
- Wet: the clutch packs are immersed in fluid, which carries away the heat of each engagement. Fluid condition therefore affects clutch life directly.
- Second generation: a revised design. Parts and fluid for an earlier dual-clutch unit should not be assumed to match.
- Low-leakage hydraulics: the gearbox actuates its clutches with fluid pressure; clean fluid at the correct level keeps that control precise.
Why the bottle matters
Fluids for wet dual-clutch gearboxes are blended for the friction behaviour of their clutch plates as well as for gear protection. ATF for a torque-converter automatic and gear oil for a manual box are made for different jobs. On the H6 GT, use only the fluid Haval names in its service data, in the quantity it gives.
The 4x4 side of the driveline
A sporty coupe-SUV with 4x4 still has the hardware of an all-wheel-drive car behind the gearbox. On the H6 GT that means checking three items at major services: the transfer or coupling unit that sends torque rearward, the propeller shaft joints, and the rear differential. Haval UAE publishes no oil data for them, so before buying anything for these units, give us the VIN.
How a tired 7DCT can feel
| What you feel or see | Worth checking |
|---|---|
| Shudder pulling away gently | Fluid condition, clutch adaptation |
| Gearbox overheating message after hard driving | Fluid temperature and level |
| Clicks on full lock | The CV joints |
| Stored gearbox faults | The control modules |
These are leads for a diagnosis, not a diagnosis.
Planning a 7DCT service
Ask the workshop three questions: which fluid Haval specifies for the second-generation 7DCT, whether the 4x4 units are due at the same time, and whether the clutches need an adaptation with a diagnostic tool once the work is done. Fluid service on a wet DCT is usually more than a drain and refill.
Fluid and gearbox parts for an H6 GT
- Routine 7DCT service
- VIN plus odometer reading; we quote the wet-DCT fluid Haval names.
- Fault already diagnosed
- Share the workshop finding; we can source clutch parts, mounts or a complete 7DCT gearbox.
- 4x4 units
- Ask us to check, by VIN, whether the rear units have their own oil due.

Frequently asked questions
What gearbox does the Haval H6 GT use?
Haval UAE lists a second-generation 7-speed wet dual-clutch transmission (7DCT); the 2025 sheet adds 4WD.
Is ATF suitable for the H6 GT 7DCT?
No, unless Haval specifies it. A wet DCT needs the fluid named in Haval’s service data.
Why does "wet" matter?
The clutches run in the fluid, so its condition affects clutch cooling and engagement directly.
Do the 4x4 parts have separate oil?
Such units are normally lubricated separately, but Haval UAE does not publish H6 GT details. We confirm by VIN.
How much fluid does the 7DCT need?
ShipMyPart has not verified the quantity; we confirm it by VIN.
When should the 7DCT fluid be changed?
Follow the service book or a Haval service centre. We don’t quote an interval until it is verified.
