Other thoughts:
And the filter is clean and seated correctly ?
Correct filter for depth of pan?
only one o-ring around the neck or inside the pump inlet?

Get yourself a pressure guage and compare main line pressure and 3rd gear pressure via the test ports [at the point when the problem occurs]. I use a std guage from a compressor with correct fittings.
