Haval Jolion 1.5 Turbo (2023): Dual-Clutch Transmission Fluid Change
The exact procedure for this model is not documented in publicly available service materials, so the general principle for dual-clutch automated transmissions is given below. Check the capacity, fluid type and torque specs against the manufacturer's service schedule. The main difficulty is setting the fluid level correctly: on this transmission the level depends on fluid temperature, so an incorrect level is common even after service. Underfilling is dangerous for the transmission.

Tools
9- Lift or inspection pit
- wrenches and sockets for the plugs (check the size on the vehicle)
- torque wrench
- syringe or pump for filling the transmission
- measuring container
- drain pan
- diagnostic scan tool that shows transmission fluid temperature
- rags
- new sealing washers for the plugs
Step by step
12 steps- Warm up the transmission with a short drive of 10-15 minutes, then park the vehicle on a level surface or lift, perfectly horizontal. Turn the ignition off.
- Remove the underbody skid plate if it blocks access to the transmission.
- Locate the drain plug and the check plug on the transmission housing. Wipe them and the area around them so dirt does not get inside.
- Place the drain pan and remove the drain plug. Drain the fluid completely and inspect it: dark color and fine suspended particles are acceptable, but large metal chips are a reason to have the transmission diagnosed.
- Measure the volume of the drained fluid so you can refill a comparable amount. Do not rely on a figure from memory; rely on the manufacturer's specification.
- If your version has an oil filter or screen on the transmission, replace or clean it according to the service schedule. Confirm whether a filter is present and where it is located when you inspect the unit.
- Install the drain plug with a new washer. Tighten to the manufacturer's torque spec; for plugs of this type it is usually 20-40 N·m (15-30 lb-ft). Do not overtighten, as the housing may be aluminum.
- Fill with new fluid through the fill or check hole using a syringe or pump, in the amount specified by the manufacturer.
- Connect the scan tool, start the engine, and use the scan tool to warm the transmission fluid to the temperature specified in the service schedule for checking the level. Cycle through the selector positions, pausing in each one.
- At the correct temperature, with the engine running, remove the check plug (if the procedure calls for it): a thin stream of fluid should seep out. If no fluid comes out, add more and repeat. If it flows out heavily, let the excess drain until it is a thin stream.
- Tighten the check plug with a new washer, within the same torque range. Check for leaks.
- Reinstall the skid plate, take a test drive, and afterward inspect the plugs for leaks. If necessary, reset the transmission adaptations with the scan tool.
Common mistakes and warnings
- This job requires an exact fluid level and control of its temperature: underfilling or overfilling leads to overheating, shuddering and clutch wear
- If you lack experience or a scan tool that shows transmission fluid temperature, go to a repair shop
- The fluid must strictly match the specification for this exact transmission; universal ATF and fluids for conventional automatic transmissions are not suitable
- Draining hot fluid can cause burns, so wear gloves
