Bulletin: 85-7-5

Date: Feb 1985

Ref.No..: 85-167-7
SUBJECT: USE OF PETROLEUM JELLY DURING TRANSMISSION SERVICE

MODELS AFFECTED: ALL AUTOMATIC TRANSMISSION


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.
