This OE Match Tiptronic gearbox service kit is a complete transmission maintenance set designed for Porsche 911 (964 and 993) models equipped with the Tiptronic automatic gearbox. The kit includes the gearbox oil filter, oil filter O-ring and oil pan gasket, providing the essential components required when servicing the Tiptronic transmission.
The oil filter sits in the bottom of the gearbox inside the transmission sump, where it filters the automatic transmission fluid (ATF) and protects the internal hydraulic system from contamination.
Fits:
Porsche 964 1990 - 1994 Tiptronic gearbox
Porsche 993 1994 - 1997 Tiptronic gearbox

Kit Includes
1 × OE Match Tiptronic Gearbox Oil Filter – 94330701102
1 × Genuine Porsche Oil Filter O-Ring – 94330704100
1 × OE Match Tiptronic Gearbox Oil Pan Gasket – 94332112307
The Tiptronic automatic transmission relies on clean transmission fluid to operate its hydraulic valves, clutches and internal mechanisms. The oil filter captures debris such as metal particles and clutch material before the fluid circulates through the gearbox system.
During transmission servicing, the oil pan must be removed to access the filter. The oil pan gasket ensures a tight seal between the transmission housing and the sump pan, while the O-ring seals the filter connection to prevent fluid leaks.
This kit provides all essential service components required for a proper Tiptronic transmission fluid and filter change, helping maintain gearbox reliability and smooth shifting.
The gearbox oil filter removes contaminants from the automatic transmission fluid, ensuring clean fluid circulates through the gearbox’s hydraulic circuits. The included seals and gasket ensure leak-free installation when the transmission sump is reassembled.
Regular replacement of these components helps maintain proper fluid pressure and smooth gear changes.
Over time, transmission filters collect debris and contaminants from internal gearbox components. If the filter becomes clogged, fluid flow may be restricted, potentially affecting shift quality and transmission longevity. Replacing the filter, gasket and seals during servicing ensures proper fluid circulation and helps protect the Tiptronic gearbox from premature wear.
When to Replace. Replace these components when:
• Performing a Tiptronic transmission fluid service
• Removing the gearbox oil pan
• The transmission filter becomes contaminated or clogged
• During automatic gearbox maintenance or overhaul

DESCRIPTION:
A competition fully synthetic transmission oil formulated using a unique combination of improved chemistry and lower friction NANODRIVE additives to massively reduce friction vs a standard oil. The Millers Oils range of competition gear oils is fully synthetic and incorporates second generation NANODRIVE low friction technology to achieve winning results in both professional and nonprofessional racing.
APPLICATION:
Designed for the lubrication of competition gearboxes. Manual transmissions, synchromesh, non-synchromesh, sequential gearboxes, transfer gearboxes, transaxles and hypoid differentials without limited slip which require API GL4 or GL5 performance. Recommended for modern transmissions where fully synthetic oil is specified, especially for high performance road and track day applications. Hewland, Xtrac, Glebe Transmissions, ZF, Tran X, Elite Transmissions, Samsonas.
Note: Not suitable for plate type limited slip differentials, instead use CRX LS 75w90 NT+.
USER BENEFITS:
• Laboratory tests and results show up to a further 15% reduction in friction and up to a further 17% reduction in wear over the previous award winning NT range
• Exceptional cold flow properties for easier gear changes
• Fast lubrication flow to component extremes on start up
• Very good oxidation resistance and superior thermal stability
• Low friction/ low drag formulation to help reduce operating temperatures
• High film strength for maximum component protection
• Significantly reduces friction, temperature, wear and minimises power loss
• Triple ester formulation works synergistically for optimised film strength and anti-wear protection
• Second generation NANODRIVE low friction technology maximises torque and power
PERFORMANCE PROFILE:
• API GL4
• API GL5
• API MT-1
• MIL-PRF-2105E
• ZF TE-ML-02B
