does anyone know what i should get and how much i'd need for an oil change?

Only use genuine Toyota Type T-IV and it supposed to need 7.2lt

I think the 7.2lt is a dry fill as there is alot of oil in the torque convertor that wouldn't come out... my mechanic only used 6lt and it's a messy-ish job so i wouldn't go doing it on the driveway

good luck

make sure u change the oil filter too when changing the gear box oil.

is that the Gearbox Oil Filter?
