Installation notes and quality

Confirm transmission code and vehicle application before installation, especially on Volvo models with Aisin 55-50SN or 55-51SN units. Match the seal dimensions to the housing bore and shaft diameter during service to ensure proper seating. InMotion specifies precision engineering and high-quality materials for this seal.
