Is Transmission Dismantling Necessary When Fifth Gear Cannot Be Engaged?

[LaneRose]

Is transmission dismantling necessary when fifth gear cannot be engaged? Below are methods to distinguish between dry and wet DCT transmissions: 1. Whether the clutch plates are immersed in transmission oil: Dry dual-clutch plates are not immersed in transmission oil; Wet dual-clutch plates are immersed in transmission oil. 2. The connecting medium between the driving and driven discs in the clutch differs: Dry dual-clutch uses air as the connecting medium; Wet dual-clutch uses oil as the connecting medium. 3. Different usage scenarios: Generally, dry types are used for short-duration semi-clutch states; Wet types are mostly used in automatic transmissions, such as the now commonly used manual-automatic integrated transmissions.
