If you are having problems with your Aisin Warner 70, 71 or 72; Look here first before assuming something is wrong internally.

If your transmission's linkage happened to come loose at the adjusting nuts or needed after a rebuild or bushing replacement, here's how to properly adjust it.

1. Properly chock wheels and jack vehicle up on the driver's side. Use jackstands to hold car up... DO NOT USE THE JACK to hold the car up unless you plan on getting severely injured or dying. No joke!



2. Be sure the shifter is set in Park. Loosen the retaining nuts for the shift control rod A and retaining arm B.

3. Check that the lever on the transmission is at the park position (first step seen from the rear). Wiggle the driveshaft to be sure it clicks into park completely.

4. Set the lever in the vertical position on the shift control rod, or just facing forward and tighten the nut. Push the retaining arm lightly to the rear until a slight resistance is felt. Temporarily tighten the retaining nut to 42 inch pounds.

5. Check that the clearance from position D towards N is the same or smaller than the clearance between position 3 towards 2 .

6. If the clearance isn't right as said above, check the following -

-If the shifter is stiff in position D , move the connecting rod 5/64" (2mm) to the rear.

-If the shifter is stiff in position 3 , move the connecting rod 1/8" (3mm) to the front.

Recheck the adjustments...if they are correct, tighten the retaining nut to 13-17 ft. pounds.

After adjustment, check all the gears with the car running and take it for a drive. If it's still not correct, your transmission may need a rebuild, or even something as simple as a new filter and fluid.
