THM 700-R4 TRANSMISSION
TO: ALL CHEVROLET DEALERS
Oil Filter Assembly:
A new design THM 700-R4 transmission fluid filter and filter seal is now available. The new design transmission filter is a wider filter that has a felt element in place of the screen element and a shorter filter neck. The filter also has a molded body that locates over the valve body bolts, thus eliminating the need for the filter retainer clip. The new design filter seal is a wider compression type seal that fits snug in its bore.
Beginning July 6, 1987 (Julian date 187) all 1987 THM 700-R4 transmissions were produced with the new design transmission filter and filter seal.
When servicing any 1982 through 1987 THM 700-R4 transmission (built prior to Julian date 187), use the previous design transmission filter and seal until current service stock is depleated. When using the new design filter and seal on any 1982 through 1987 THM 700-R4 transmission (built prior to Julian date 187), the filter retaining clip is not needed and should be discarded.
NOTE: Care should be taken when installing the new design filter and filter seal. The filter seal is a compression type seal and will fit snug in its bore. Damage to the filter neck could result if the filter is installed incorrectly.
To correctly install the filter and seal, coat the seal with petroleum or Automatic Transmission Fluid and with the seal over the filter neck, insert the filter into its bore in the pump assembly. With the palm of your hand gently push downward on the filter until it seats.
