When it’s time to change the transmission and rear differential fluid, these kits make it easy. You get enough Motul transmission fluid for your gearbox, in the formula of your choice, and a bottle of fluid for the rear diff.
Tech note: Some people have called us asking, “How come you only include four liters of trans fluid when my service manual says more?” The answer is that when you’re changing the fluid, a lot of the fluid is going to stay in the transmission, stuck between the gears and other parts. The result is that it takes less fluid than the manual specifies to fill the transmission full. The amount we sell in these kits is just the right amount for your fluid change.
