The exact configuration of the parts may vary slightly in specific valvebodies. Only two valve cover-plates need be removed: the large seven-orifice plate held in place by eight bolts (A ) and a single-orifice two-bolt plate on the opposite side (8). Note the early model twobolt plates slot orientation. Remove only the parts necessary to replace those referenced in photos 0916. Use a pick, magnet, or small screwdriver if the parts don't pop out of theirorifices. 09? Pressure regulator circuit under the two-bolt plate: For the firmest shifts, replace the stock outer spring with the kit's orange spring. The kit's blue spring willyield firmer-than- stock shifts, but not asfirm as the orange one. Either way, if there is an innerspring, reuse it. When bolting on the plate, be sure its slot lines up with the valvebody hole (arrow). 13 All C6 check balls have the same Va-inch diameter. Reuse the original check ball(s) in their original locations. 1976-and-earlier bodies use only the top ball as shown in photo 08 and 16; 1977-and-later also have a lower ball. It cant hurt to put a dab of petroleum ielly on the balls to hold them in place. 80 HOTROD.COM/2019/APRIL/ 10 Underthe seven-port cover-plate, replacethe outboard stockservo modulator-valve spring with the kits yellow spring. llo Reuse the originaltorque converter pressure relief valve and spring at its original location (photos 08 and 16). A /1.-inch check ball was used in lieu of a valve in early1967 production. 11: Remove the stock accumulator- valve spring. replacing them with the kit's white spring inserted inside the kits pinkspring. 15 15: Reuse the original throttle pressure relief check ball and spring at its original location. This spring is slightly shorterthan the converter pressure relief spring. 12 1 Remove the stock cut-back valve. Install the kits black spring into the orifice, then reinstall the cut-back valve after it. 0E bodies dont have a cut-back spring. Adding the kit's spring yields extremely firm shifts by preventing movement of the cut- back valve. If the new spring holds out the valve cover-plate during its reinstallation, grind or clip two coils offthe spring. 16 16 For even more bulletproofing, you can optionally drill a Via-inch hole using the kits supplied drill bit in the highlighted yellow area to prevent loss of converter lubrication during heavythrottle. This photo also shows the installed check ball (A) and pressure relief valve and spring (8).
