My transmission bagan slipping badly on upshift then lost all forward gears completely. Reverse works with the lever either in reverse or first gear position. I removed the pan and found a small metal part in the pan. It is shaped sort of like the fearher-end of an arrow. It has a unthreaded hole in one end and a 'V' in the other. It is approx 1.25 inches from the hole to the 'V' and 1 inch at the span of the 'feather'. If this helps any: A few weeks before the complete failure I could not for the transmission into park even if I disconnected the linkage and shifted at the transmission. Any ideas are greatly appreciated.
