A/T - Forward Clutch Plate Modification


Number 85-7-16 Date 4/85

Subject: FORWARD CLUTCH PLATE ASSEMBLY

ALL 1982-1985 THM 700-R4


At the start of production of the 1985 THM 700-R4 transmission, ALL MODELS will be built with thicker steel clutch plates and thinner composition clutch plates in the forward clutch assembly.

NOTICE: THE THICKNESS CHANGE IN THE PLATES DOES NOT AFFECT THE OVERALL "STACK UP" DIMENSION FOR THE FORWARD CLUTCH ASSEMBLY WHEN USED IN SETS AS SHOWN BELOW. DO NOT MIX THE NEW PLATES WITH PLATES FOR TRANSMISSIONS BUILT PRIOR TO THE 1985 MODEL YEAR. USE A MICROMETER TO INSURE THE PROPER PLATE USAGE.
