Castrol offers a wide range of manual transmission fluids, from fully synthetics which can cover the needs of the latest transmissions to high quality minerals for use in older high mileage cars.
The manual transmission fluid plays an extremely important role to the proper operation of your transmission as it will keep it lubricated and protected from heat and wear. If the wrong fluid or one in a deteriorated condition is in use the transmission will most likely experience problems such as gear stiffness, gear tooth wear and eventually, parts damage.
Castrol’s manual transmission fluids help your transmission stay well protected and help you avoid unexpected repairs which can be very expensive.
Always consult your car’s handbook to make sure you find the correct fluid for your transmission.
