Is the Geely Boyue's Dual-Clutch Transmission Dry or Wet?
2 Answers
Geely Boyue's dual-clutch transmission is a 7-speed wet dual-clutch, jointly developed by Geely and Volvo. Here are some potential issues that may be encountered with dual-clutch transmissions: 1. Transmission jerking. 2. Sometimes lurching forward when waiting at a red light with the brake pressed in D gear. 3. Unsteady gear shifts during acceleration. 4. Occasionally, the vehicle may not move when pressing the accelerator in reverse or forward gear. 5. Occasionally hearing a clunk sound from the left front wheel when starting. Below is an introduction to dual-clutch transmissions: 1. Compared to traditional AT transmissions, dual-clutch transmissions use clutches as transmission connection components, offering superior shifting speed and power transmission efficiency. 2. Structurally, the internal design of dual-clutch transmissions is similar to manual transmissions, both using gear meshing for transmission, whereas AT transmissions use planetary gear sets internally, making them relatively more lightweight.
I've been driving the Geely Boyue for a long time, and its dual-clutch transmission is the wet type, not the dry one. The wet design has oil cooling, making driving exceptionally smooth, especially in city traffic with stop-and-go conditions—I've never encountered overheating or shuddering issues. Compared to dry types, wet ones are more durable, with better heat dissipation and lower failure rates, making them ideal for daily commuter cars like ours. I've read some reports that dry dual-clutch transmissions can easily burn out with frequent gear shifts, but the wet one in the Boyue has been worry-free. I recommend owners pay attention to maintenance, such as changing the transmission fluid every 40,000 kilometers, which can extend its lifespan by several years. Overall, the wet dual-clutch transmission makes driving more comfortable and safer, which is why I recommend it.
