Manufactured to OEM specifications, this component is essential for preventing fluid leaks, maintaining correct pressure, and ensuring reliable transmission performance.
Key Features
• Direct replacement ATF reservoir cap seal
• Designed for automatic transmission filler neck
• OEM-style fit and function
• Helps prevent fluid leaks and contamination
• Durable material for long-term performance
• Essential maintenance component
Function and Purpose
The ATF cap seal ensures a tight seal between the filler neck and cap, helping to maintain proper transmission operation.
It helps to:
• Prevent transmission fluid leaks
• Maintain system pressure and cleanliness
• Protect against dirt and contamination
• Support long-term gearbox reliability
Why Replace Your ATF Cap Seal
Over time, seals can degrade due to heat, fluid exposure, and age.
Common issues include:
• Fluid leaks around the filler cap
• Hardened or cracked seal material
• Loss of sealing performance
• Contamination risk
Replacing the seal ensures continued reliability and proper transmission function.

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
