Geely Tugella Transmission Fluid: 8AT and 4WD

Launches, paddles and fluid temperature

Quick getaways and holding gears manually in Sport mode keep the gearbox working at high load. Each hard launch makes the torque converter slip briefly while it multiplies torque, and that slip ends up as heat in the fluid. One quick drive is no problem; a habit of hard launches in summer ages the fluid faster than gentle driving. If that is how the car is driven, mention it when you ask about the service schedule.

Four wheels, more than one oil

The 4WD system adds hardware between the gearbox and the rear wheels: a coupling or transfer unit and a rear differential. These usually run on their own lubricants rather than on ATF. Geely's page does not say which are filled separately, so we confirm it from the VIN rather than guess.

Tyre choice and the 4WD system

Sporty SUVs often get tyres replaced in pairs as the fronts wear faster. On a 4WD car, different tread depths front and rear mean the axles turn at slightly different speeds, which the 4WD coupling has to absorb. Keeping four matching tyres is part of looking after the driveline, not only the handling.

Questions to bring to a workshop

• Does the gearbox hesitate or flare between gears when hot?
• Is there a clunk through the mounts when changing direction?
• Does a 4WD or drivetrain warning appear after spirited driving?
• Is there a rumble from the rear or a click from the axle joints on full lock?

Answers like these help a workshop decide between fluid, the control electronics, the coupling or a mechanical part.

Booking the gearbox service

1. Before: note when the car shifts oddly, hot or cold, and since when.
2. At booking: give the VIN and say if the car is driven hard; it may change the schedule.
3. On the day: confirm the ATF name and drain-and-fill quantity Geely lists, and whether the 4WD unit and rear differential are included.
4. After: keep the invoice with the fluid names for the next owner or service.

Driveline fluids for a Tugella

Tell us the VIN and how the car is driven (mostly city, regular motorway, or frequent spirited driving). We confirm the fluids Geely lists for the gearbox and 4WD units and send one quote, including the gearbox or other parts if a workshop has diagnosed a fault.
