My car is a half year car with the 4.6L and the 4r70W. My original slip yoke is damaged from when the old transmissions tails shaft came loose and cut groves into the old slip yoke and now leaks past the seal. I having a hard time finding a replacement that actually fits. I ordered the Ford Racing M-4841-B but the outside diameter on the shaft is around ~4mm too small and does not touch the bushing. Does anyone know the actual dimensions or part number for a factory slip yoke?
