Hi Phil

Well, I am stumped. I tore it down then replaced all the pads etc al o rings and what not. Tore apart the valve body too cleaned and changed the gasket and reassembled then reinstalled it in the car. Hooked up the cooler lines and did not notice that cooler oil line o rings had sloped and where cut. Basically they got sucked in to the cooler then back into the pump. Hoarse when filling with oil everything was fine then after putting in about 8 quarts when I put in reverse I hear shutter noise then if try to place it in park I hear loud shutter like as if it was a manual tranny when you fail to compress the count correctly or signage into the gear correctly that metal shutter grinding sound i hear the when putting it in park. I've reopens the funny but found fine rubber dust looks like the pump grinder down the half of the o ring. So and suggestikns
