The gearbox oil drain plug provides the removable sealing point used when draining transmission fluid during servicing. Once installed and correctly tightened, it must maintain a reliable seal and prevent automatic transmission fluid from escaping from the gearbox.

Although simple in design, the drain plug performs an important role. Automatic transmissions depend on maintaining the correct quantity of specified transmission fluid for lubrication, cooling and hydraulic operation. A damaged plug, worn threads or compromised sealing surface can cause fluid seepage and, if ignored, potentially reduce the gearbox oil level.

Drain plugs can deteriorate through repeated removal, overtightening, damaged threads, corrosion or incorrect tools. Replacing a questionable plug during transmission servicing with the correct OE Match Tiptronic Gearbox Oil Drain Plug helps provide a dependable seal and reduces the risk of future leakage.

What This Product Does:

• Seals the transmission oil drain opening.
• Prevents transmission fluid from escaping during normal operation.
• Allows gearbox oil to be drained during servicing.
• Helps maintain the correct transmission fluid quantity.
• Supports a clean, leak-free gearbox installation.
• Helps protect the transmission from fluid loss.
• Provides a secure closure after transmission servicing.
• Replaces a damaged, worn or corroded drain plug.
• Helps prevent leakage caused by damaged drain-plug hardware.
• Provides an OE Match replacement for compatible Porsche Tiptronic applications. 

• An automatic transmission relies on maintaining the correct fluid level.
• A leaking drain plug can gradually allow transmission fluid to escape.
• If the fluid level falls sufficiently, gearbox operation may be affected and internal components may experience inadequate lubrication or hydraulic pressure.
• Replacing a damaged OE Match Drain Plug helps restore a secure sealing point and protects against avoidable transmission-fluid loss.
