Subject:
USE OF PETROLEUM JELLY DURING TRANSMISSION SERVICE
ALL AUTOMATIC TRANSMISSIONS
During transmission reassembly the check balls and thrust washers should be retained with a white petroleum jelly. Any other grease will most likely
have a higher melting temperature than petroleum jelly and may cause coating and plugging of the oil filter screen, resulting in transmission failure.
