7. Clean your stock manual valve by dipping it in clean transmission fluid and install into the ATI valve
body.
8. Remove two (2) filter retaining screws, filter, and the filter gasket from your stock valve body and install
onto your ATI valve body. If your filter screen is torn or clogged with debris, you should replace it with a
new filter. Tighten the filter retaining screws securely.
9. Double check the transmission case and make sure that there are no pieces of old valve body gasket
remaining on the valve body mating surface of the case. Use a single edge razor blade or a gasket scraper
to remove any remaining debris. Install the servo supply tube into the ATI valve body and install the valve
body while carefully guiding the tube into its bore in the transmission case. Also align the manual valve
groove with the selector lever pin as you make the installation. Be sure to rotate the detent roller assembly
so that the roller end is pointing towards the front of the case in order to line up the roller with the inner
lever detents.
10. Install the detent guide plate and seven valve body retaining bolts and hand tighten. Make sure that the
pin on the selector lever remains in the groove of the manual valve. You may need to tap lightly on the
servo supply tube to completely seat it into the case. Install the remaining detent plate bolt and torque all
eight bolts to 120 in. lbs. or 10 ft. lbs. Install the detent roller spring.
11. Adjust band: Adjustor is located on the driver's side on the outside of the transmission case. Use the
appropriate size wrench to loosen the locknut. The most common wrench sizes for the lock nut are 9/16"
and 11/16". Holding the locknut, use a 7/32" allen wrench and turn the round lug in the center of the locknut
until the wrench becomes snug or torque to 80 in. lbs. Make sure that your locknut is not impeding the
movement of the adjustor. Carefully turn the adjustor lug counter clockwise 3 1/2" full turns. Hold the
adjustor with your allen wrench and tighten the locknut securely (35 ft. lbs.) Do not allow the adjustor lug
to move while tightening the locknut.
12. Remove any pieces of old pan gasket from the transmission case and oil pan. Clean oil pan and install
using a new pan gasket. Secure all pan bolts evenly and then torque them to 150 in. lbs. or 12 ft. lbs. If
you have removed a drain plug, install it now and tighten securely.
13. Always check shifter adjustment after installation. Never adjust the shifter linkage or cable in "PARK" position.
Always start adjustment / alignment with the shifter and the transmission in high gear. After setting the
cable or linkage in high gear, make sure that your linkage or cable aligns perfectly with the transmission
lever in all other gear positions. Proper shifter adjustment is vital and critical to proper operation of the
transmission. Do not operate without verifying proper shifter adjustment! Secure your linkage or cable
appropriately when finished.
14. Lower the vehicle. Keep the rear wheels off the ground if possible. Pour in four (4) quarts of automatic
transmission fluid. ATI recommends using a quality brand of Type F fluid. Start the engine with the
transmission in NEUTRAL. Check the fluid level with the dipstick and continue adding until it has reached
the ADD mark on the dipstick. With the brakes on, select each gear position for several seconds each in
order to fill all oil circuits. Select the neutral position again and recheck the fluid level. If the level is at the
ADD mark when the fluid is cold, it will probable reach the FULL mark after the transmission has reached
operating temperature. DO NOT OVERFILL!
• For reverse pattern valve bodies - Never attempt to NEUTRAL the transmission during a shut
down. Keep the transmission in high gear while slowing the car.
• Always begin your burnout in first gear and then shift to high gear. Drive the car out of the
water under power and lift before the tire hooks. Never allow the tires to hook during a burn
out as this can cause sprag failure.
• For your own protection, never operate without an approved transmission shield.
