ATP HO-9

ATP HO-9 is an automatic transmission extension housing seal / rear transmission seal. It seals the transmission output area where the output shaft and driveshaft slip yoke pass through the rear extension housing.

Application / fitment

This seal is used in automatic transmission rear housings where the driveshaft slip yoke runs through the rear output seal. Fitment should be checked by seal position, extension-housing type and HO-9 part number; detailed dimensions are grouped in the technical section.
