Automotive transmission fluid engineered to improve shift feel and protect manual gearboxes. Drivers who value confident, crisp gear changes will appreciate the refinement of Castrol Transmax Manual FE Gearbox Oil. Is it the right choice for vehicles that require specific manufacturer approvals and GL-4 lubricants?
⚡ At a Glance
- • Friction Control: Active control molecules adjust friction under changing pressures and speed for smoother shifts
- • Best for: Owners of manual and dry-clutch passenger cars needing API GL-4 compliant transmission fluid
- • Not ideal for: Automatic transmissions or gearboxes specifying API GL-5 or other non-GL-4 fluids
Full synthetic, low-viscosity manual transmission fluid meeting API GL-4 and multiple manufacturer approvals. Smooth Drive Technology regulates friction dynamically to improve shift quality while protecting gear components.
Smoother Gear Changes - Thanks to Smooth Drive Technology
Formulated with Smooth Drive Technology, active control molecules automatically adjust friction levels as pressure and speed vary, reducing variability in clutch engagement and gear selection.
More consistent, crisper gear shifts are noticeable in everyday driving, especially in stop-start urban conditions and during low-speed manoeuvres.
Improved Wear Protection - With a full synthetic, low-viscosity formulation
A low-viscosity synthetic base combined with GL-4 additive chemistry helps maintain oil film strength while resisting shear, meeting API GL-4 and MB-Approval 235.73 specifications.
Reduced wear on gears and synchros supports longer transmission life and dependable performance over typical service intervals.
Broad Manufacturer Compatibility - Thanks to multiple approvals
Meets API GL-4 and is listed as MB-Approval 235.73, and meets Ford WSS-M2C200-D2; specifically approved for the Smart DC transmission BR 453 from Getrag.
Suitable where those specifications are required, including a range of Ford and Volvo passenger cars named by the manufacturer.
