I have never been able to get a good reading on the dipstick with this PA deep pan. Theoretically it should take nearly 16 quarts to fill. I just installed my rebuilt trans and PI TC. Poured one quart into the TC then added 12 more to the trans. Had the car running up to temp and it read between the cross hatch area. I followed the procedure of going thru the gears as I filled it too. Took it for a drive and now it reads overfilled. How is this possible with only 13 quarts in there? Seems I should 3 quarts low not overfilled. Any ideas?
