A/T - 3-2 Too Sensitive, or No Part Throttle Downshift

TSB 87-1 (Jan)

SUBJECT: FORD AOD

PROBLEM:
Too sensitive 3-2, or no 3-2 part throttle downshift.





CAUSE:
May be a sticky 2-3 TV modulator valve. If it sticks c1osed, it can cause a no 3-2 part throttle downshift. If valve sticks open, it can cause a too sensitive 3-2 downshift.

SOLUTION:
Clean the valve, and re-assemble, making sure that a magnet will stroke the valve fully. Torque the valve body in proper sequence.

We recommend approximately .060 inch pounds on a problem unit.
