Late reply but still... Steve's theory that the pipe plug is a level plug is wrong. That plug hides the retainer for one of the
input shaft bearing outer races. The ZF manual that I've seen offered does not cover the Dash-1 despite claims of doing so. It covers the Dash-2 and the Dash-0. The oil volume of 3.5 pints is for the Dash-0. The exploded view shown here is also for a Dash-0. Note the different shifter housing. I highly doubt that the Dash-1 on Mangusta configuration is happy with as little as 3.5 pints in the long run. The Dash-1 in Pantera config takes as much oil as a Dash-2 in Pantera config.
