Red Line 50604 MT-LV 70W/75W GL-4 Manual Transmission Gear Oil - 946ml
Full-synthetic Red Line transmission lubricant for manual transmissions, transaxles and specifically supported applications requiring SAE 70W/75W API GL-4 or an approved equivalent specification as listed in the compatibility table.
MT-LV is a low-viscosity ester-based transmission lubricant developed to provide strong gear and synchroniser protection while maintaining the friction characteristics required for positive synchroniser engagement and smooth gear changes.
The low-viscosity formulation helps reduce fluid drag and improve cold shifting while remaining shear-stable for consistent viscosity during extended use. Red Line also identifies MT-LV as suitable for dual-clutch applications that specifically require GL-4 gear oil.
MT-LV is safe for brass synchronisers and is recommended by Red Line for API GL-4, GL-3 and GL-1 applications, along with many special synchromesh-fluid requirements. It should not be used in hypoid differentials.

Fitment advice: Use MT-LV where SAE 70W/75W API GL-4 manual transmission oil or one of Red Line's specifically listed equivalent specifications is required. This product should not be selected for a differential simply because a similar viscosity is specified.
Other items to consider: When servicing a manual transmission or transaxle, you may also want to consider purchasing replacement drain and fill plug washers, seals and related drivetrain service components where required.
Useful tools / consumables: Fluid transfer pump, drain pan, suitable sockets or spanners, torque wrench, gloves, workshop towels and brake cleaner for external clean-up.
Difficulty guide: DIY Difficulty: Moderate. Fluid replacement is generally straightforward, but correct lubricant specification, drain/fill procedure and fluid level are important.
Why Red Line? Red Line Synthetic Oil is known for high-performance lubricants, fluids and additives developed for demanding road, track and motorsport use.
