| Valvebody Installation Instructions. |
| 1) | Raise vehicle, place on jackstands. Allow to cool. Hot trans fluid can cause burns! |
| 2) | Carefully disconnect the harness plug from the valvebody connector. (Drivers side of vehicle, just to the rear of the shifter arm mechanism). Extreme care must be taken not to damage the connector or pins in the harness. Pins and plug are small and delicate and must not be damaged. |
| 3) | Place large drain pan under transmission pan. Loosen pan bolts on three sides of pan. Remove bolts except for two bolts on one end of pan, and one bolt on the other end. Slightly loosen the two bolts on one end, then loosen the remaining bolt. Allow the pan to hang at an angle and drain into the large drain pan. Continue loosening the one bolt until pan has drained most of the fluid out. Then, hold pan up level with one hand while removing the remaining bolts. Lower pan and drain out fluid. Observe the inside of the pan to see if there are particles in the pan. |
| NOTE: Before continuing, make certain the Pressure Solenoid on the side of your new Valvebody matches the solenoid on your existing valvebody. One type has a square plug, (2000 or newer) while the other style (96-99) has a oval plug on it. If solenoids do not match, do not continue with installation! Contact your salesperson for the correct resolution. |
| 4) | Remove the TV cable from the ball stud on the TV arm. Loosen the TV arm bolt and remove the TV arm. Note orientation of arm, make sure arm goes back on the same way it was removed. |
| 5) | Remove the Shifter cable and shift the trans into low position. (This will assist in removing the park rod clip later). Remove the shifter arm. |
| 6) | Remove the e-clip holding the Park Rod (long rod extending back into the rear of the transmission) to the valve body shift actuator. Be careful not to lose the e-clip! Pull the Park Rod loose from the shift actuator and push it towards the rear of the trans. |
| 7) | Remove the perimeter bolts holding the valve body to the trans case. The Filter bolts do not go into the case and do not need to be removed to remove the valve body. NOTE: If the valvebody does not loosen slightly after the bolts are removed, you have missed a bolt! Once all bolts have been removed the valvebody will be noticeably loose. However, due to the 0-rings on the valvebody electrical plug and the seal on the shifter shaft which stick up through the trans case, you will need to pull the valvebody out of the transmission by wiggling straight down (you might need to lightly push down on the harness connector on the outside of the case while pulling down on the valvebody. Once the o-rings have cleared the case the valvebody will come out. |
| 8) | Once the valvebody is removed the accumulator piston and spring will probably fall out. You will not be using the spring, so discard it. The Piston will be re-used. It goes into the hole in the trans case with the small end with seal ring end going into the trans. (See Photo) |
| 9) | Place the supplied spacer between the piston and the bottom of the accumulator well in the trans case. Insert the accumulator piston into the well (you might need to apply a small amount of Vasoline to the edges of the accumulator piston to retain it in the well while you install the valvebody). Make certain the piston seats fully against the supplied spacer in the piston well. NOTE: The new style spacer is a ring, not a shaft as shown in the photos. This ring will set on the small end of the piston, acting as an extension of the piston. |
| 10) | Place a small amount of Vasoline on the o-rings around the valvebody electrical plug where it seals to the trans case. Insert new valvebody into trans case being careful not to damage the Electrical connector o-rings or the shifter shaft seal. NOTE: If the valvebody does not set flush with the trans case with hand pressure the accumulator piston is probably not seated. Do not tighten any bolts until valvebody will set flat against the trans case!!!! Snug bolts, then tighten to 110 Inch Pounds! Make certain the correct length bolts go back into the holes they came out of! |
| 11) | Re-install remainder of components as removed (don’t forget to install the Park rod and e-clip). Install trans pan and fill to proper level with vehicle level, idling in Neutral, and fluid at operating temperature. You will probably need about 10 qts of fluid. |
| Tip; While pan is off consider adding a drain plug for future convenience. |
