If the screen in the bottom of the tranny is clean, take apart and clean the valve body device near the oil filter. Actually, before that, make sure the screw under the hex nut is closed up tight with a screwdriver and reinstall the hex nut. That runs the return oil back into the cir cut feeding the pump rather than into the sump first.That little reservoir in front runs out real fast when you push the clutch otherwise.When its screwed in the return helps feed the piston pump a stream of returning oil.
