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.
Symptoms Of Wear Or Failure:
- Transmission fluid leaking around the drain plug.
- Wetness around the gearbox drain point.
- Oil droplets beneath the transmission.
- Transmission fluid level falling.
- Visible damage to the drain plug.
- Rounded or damaged tool engagement surfaces.
- Damaged threads.
- Corroded drain plug.
- Plug difficult to remove.
- Plug difficult to tighten correctly.
- Leakage following a gearbox oil service.
- Damaged or distorted sealing surface.
- Evidence that the plug has previously been overtightened.
- Plug repeatedly working loose.
- Sealing washer or seal damage where applicable.
Why Replacement Matters:
- 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.

Genuine Porsche Original Equipment (OE) oil strainer (transmission oil filter) designed for use in the automatic transmission/gearbox of compatible Porsche models. This oil strainer fits inside the automatic transmission fluid circuit to screen out contaminants and particles from the transmission oil, helping protect valves, pumps, and internal gears from premature wear.
Fits:
For cars with Automatic transmission
Porsche 924 1976 - 1985
Porsche 924 S 1986 - 1988
Porsche 944 1982 - 1989
Diagram ref no 8
The transmission oil strainer filters out metal shavings, debris, and other contaminants from the transmission’s fluid before it reaches critical hydraulic components. This helps the gearbox operate smoothly, reduces friction and wear on moving parts, and extends service life.
Function: Installed within the transmission’s sump or oil circuit, the strainer traps foreign particles and prevents them from circulating through the gearbox. By maintaining cleaner oil flow to the pump and valve body, it supports consistent hydraulic pressure, smooth shifting, and reduced risk of internal damage.
Over time, transmission oil strainers can become clogged with debris, reducing fluid flow and increasing wear in the transmission’s internal components. A worn or restricted strainer limits hydraulic performance, can lead to rough shifting or overheating, and may shorten transmission life. Replacing restores correct filtration, maintains fluid cleanliness, and protects the gearbox’s mechanical and hydraulic systems.
When to replace:
• During automatic transmission service or fluid change
• When transmission exhibits sluggish or rough shifting
• After extended mileage or high-heat operation
• If transmission fluid shows signs of contamination or debris
• With intermediate servicing at factory-recommended intervals
