Hi all. I just got my ZF 6peed auto back from a rebuild and its bone dry! My question is how do I safely and correctly fill the gearbox up with oil. I know I can remove the filler plug and pump oil into the box until it trickles out of the filler plug hole... but surely that's not the total amount. I dont want to crank my car over with no oil in my pumps and throughout the rest of the box and damage anything or is this the only way? P.S. I will fill my tourqe converter with 1l of oil or so before intallation. PLEASE HELP!
