Is the Song Pro Transmission Dry or Wet?

[McReese]

Song Pro's transmission is the BYD6DCT35 six-speed wet dual-clutch. Introduction to Dry Dual-Clutch: A dry dual-clutch can be understood as a combination of two sets of ordinary manual transmission clutches, with two clutches controlling two input shafts to deliver power to the transmission. This design aims to improve shift speed and transmission efficiency, so dual-clutch transmissions are always very proactive in shifting. Frequent shifting equals frequent semi-engagement of the clutch, which means high-frequency sliding friction between the flywheel and the clutch. Durability: The 1.5T direct-injection turbocharged engine paired with the Song Pro has a peak torque of only 245Nm (1600-4000 rpm), and the ample torque margin indicates the durability of this transmission. Function: The BYD Song Pro fuel version comes standard with a 1.5T high-efficiency engine, model number BYD476ZQB. The wet transmission places the clutch in an oil chamber, where it is lubricated and cooled by transmission oil flow.

I've done some research on the Song Pro's transmission. Its automatic transmission uses a wet dual-clutch system, not a dry one. This design primarily enhances durability and heat dissipation, making it particularly suitable for stop-and-go city driving scenarios, reducing the likelihood of overheating issues. The wet clutch is immersed in oil, providing better lubrication, reducing clutch plate wear, and delivering smooth gear shifts with quick response. Of course, maintenance requires regular checks of the transmission oil to prevent performance degradation due to oil aging. In comparison, dry DCTs are more common in compact cars but are prone to wear and may overheat during prolonged traffic jams. The Song Pro's choice of a wet clutch is a smart one, balancing reliability and comfort. If you're an owner, regular maintenance can extend its lifespan. While repairs might cost a bit, overall it's more worry-free.

I usually drive the Song Pro to work and feel its transmission is the wet type. When I first bought the car, I specifically checked – wet dual-clutch transmissions are more suitable for daily commutes, with better heat dissipation, so you don’t have to worry about overheating in traffic jams like with dry types. After using it for a year or two, the gear shifts are indeed smooth, acceleration response is quick, and there’s no noticeable jerkiness. During routine maintenance, the mechanic suggested changing the transmission fluid every two years to keep the system clean. This is simpler than maintaining a dry DCT, which demands more careful driving habits—aggressive acceleration can easily cause issues. I think the manufacturer made a wise choice by opting for a wet transmission in the Song Pro, reducing failure rates and improving fuel efficiency. It performs stably on highways. If you’re curious about the details, you can visit a 4S shop for a comprehensive transmission inspection to ensure everything is in good condition.

Let me talk about the Song Pro's transmission from a repair perspective. It basically features a wet dual-clutch design, with the clutch operating immersed in oil, making it more durable than dry types. Common issues like oil leaks or unstable oil pressure require professional tools for diagnosis, rather than simply replacing parts. During maintenance, priority should be given to checking the transmission fluid level and quality, as contamination can affect gear shifting. Most owners report that the wet clutch performs reliably in the Song Pro, with rare occurrences of abnormal noises or jerking, and it's more tolerant than dry types under harsh conditions. The repair cost is slightly higher, but it avoids the hassle of frequent repairs. Regularly using a diagnostic tool to read fault codes can prevent major problems.
