    When shifting from forward to reverse and reverse to forward oil pressure drops to zero for a spit second
    then pops back up to normal. Oil level is correct. I shift very slow. Wait for a second in neutral.
    Oil filter screen is clean.
    Any thoughts?
    Thanks

    Over all pressure is measured when in gear.
    My 514s read around 150 in gear. At idle in neutral maybe 20 when warm.
    If your using the correct fresh oil, clutches engage solid, I do not see any issue in what you have typed.
