Description:
The DQ381 (0GC) plug set is used to seal between the transmission rear cover and the transmission housing. This gasket prevents transmission and hydraulic oil leakage, helping to maintain system pressure. Proper sealing ensures that internal components remain continuously and adequately lubricated, reducing wear and ensuring smooth transmission operation.

The plug set also plays a critical role in preventing pressure loss, oil leaks, and related gear shift issues, performance reduction, and premature component failure. During maintenance, repair, or transmission disassembly, it is recommended to replace old or damaged gaskets with new ones, as a deformed gasket can cause vibrations, oil leaks, and long-term serious mechanical damage.
