Got three gallons or 11.35623 L of
Castrol 03521 Transmax Import Multi-Vehicle Automatic Transmission Fluid - 1 Gallon, (Pack of 3) for 66.72 shipped from Amazon and the Filter Kit 5HP24 for $82.65 shipped from CTSC. Now I can run almost 12 litres through it and hopefully it lasts a goood long time.
Thanks for all teh input everyone.
