How reliable is the DQ400E transmission?
2 Answers
Reliability is quite good, having been validated by the market. Below is relevant information about the DQ400E transmission: 1. Overview: The DQ400E hybrid transmission is based on Volkswagen's mature wet DSG transmission with design modifications. It integrates a flat permanent magnet synchronous motor at the front end of the transmission, while a set of wet clutch is arranged between the motor and the engine input. 2. Advantages: When driven by the motor, the vehicle is almost silent; when the motor and engine output simultaneously, the two forces combine strongly to release powerful and efficient power. This allows users to fully enjoy a low-carbon driving experience with rich driving pleasure.
I've been driving this Golf GTE for 6 years with 120,000 kilometers on it, using the DQ400e transmission, and it's really never had any issues. My daily commute is 40 kilometers, with occasional highway trips on weekends, and the most noticeable thing is how fuel-efficient and smooth it is. In hybrid mode, when the electric motor and engine switch, you can only hear a slight click if you listen carefully, and the vibration when idling with the AC on at a red light is much less noticeable than in a pure gasoline car. The downside is that during low-speed crawling in traffic, the throttle needs to be controlled very delicately, otherwise it's easy to get a jerky motion—probably an issue with the coordination between energy recovery and the clutch. For maintenance, I recommend having the mechanic check the transmission fluid level carefully, especially since hybrid systems generate a lot of heat.
