This cancels and supercedes Chevrolet Dealer Service Bulletin 84-107 dated April, 1984 which should be destroyed. This bulletin
updates model year usage and supplies additional information pertaining to checking for bleed-off of the orifice cup plug.
FIGURE 7 - Bleed Orifice Cup Plug
Starting production of all 1985 THM 700-R4 transmissions an air bleed orifice cup plug was added to the input clutch housing (Figure
7). Due to this change, the procedure listed below for air checking the 3-4 clutch piston and the check ball has been revised.
Some 1982-84 THM 700-R4 transmissions may exhibit a burned 3-4 clutch, and/or high 2-3 shifts. (The high 2-3 shifts are experienced
on "C/K/G" truck gas/diesel applications only.)
