The 94330701102 OE Match gearbox oil filter is a transmission service component designed for Porsche 911 (964 and 993) models equipped with the Tiptronic automatic gearbox. This filter installs inside the gearbox oil pan at the bottom of the transmission and filters contaminants from the automatic transmission fluid (ATF).
Fits:
Porsche 964 1990 - 1994 Tiptronic gearbox
Porsche 993 1994 - 1997 Tiptronic gearbox
Diagram ref no 9
The Tiptronic transmission uses hydraulic fluid to operate internal components such as clutches and valves. The oil filter removes metal particles, clutch debris and other contaminants from the transmission fluid as it circulates through the system.
Located in the lower section of the gearbox sump, the filter protects sensitive internal components by ensuring only clean fluid passes through the hydraulic system. Over time, filters can become clogged with debris, reducing fluid flow and potentially affecting transmission performance.
The OE Match version of this filter replicates the factory specifications used in Porsche 964 and 993 Tiptronic transmissions, providing a direct-fit solution for transmission servicing.
The gearbox oil filter keeps the transmission fluid clean by trapping contaminants before the fluid is circulated through the transmission’s hydraulic circuits. Clean transmission fluid helps maintain smooth gear changes and protects internal transmission components from premature wear.
Replacing the filter during routine transmission service ensures proper fluid circulation and reliable automatic gearbox operation.
Transmission filters gradually accumulate debris from clutch material and internal wear. If the filter becomes clogged, it can restrict fluid flow and negatively affect shifting performance. Replacing the filter during transmission service helps maintain clean hydraulic fluid and protects the gearbox from premature wear.
When to Replace. Consider replacing the gearbox oil filter when:
• Performing Tiptronic transmission fluid service
• Transmission shifting becomes less smooth or delayed
• The gearbox sump is removed for maintenance
• During gearbox rebuild or overhaul
