A/T - Use of Petroleum Jelly During Transmission Service
Number: 85-7-11 Date: 2/85Subject: 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.
