-It's important that your transmission gearbox temperature reaches 80 degrees Celsius before check the fluid level. The level must be between the low and high fill marks. If its too high please drain off excess fluid by removing the drain bolt (you do not have to drain the whole transmission again).

-Regarding the transmission pan- Please remove the forward bolts first then the middle bolts as this will remove the excess oil that is left behind in the transmission pan.

-To protect your pan bolts, apply Copper Slip anti-seize compound to the threads to prevent corrosion.

The quantity of fluid to be replaced varies from car to car.
7.5 liters is recommended for the initial fill. It's also recommended to have a few liters extra as a backup, however you may not use all 7.5 liters. (We only used 3.5 liters and It's ok to mix old fluid with new fluid).

Torque specs:
Transmission pan bolts: 8Nn.
