JoeS, regarding OD cable creep: first, could you clarify the situation? You stated when 'out of overdrive the cable creeps toward engagement.' Does this mean that when you have the dash knob pulled out (OD Locked out), the knob begins to move back toward the fully in position (OD allowed/enabled)?

If this is indeed the scenario, then HH is correct, the cable could provide some some resistance. However, if the cable is disconnected at the lock out arm on the OD, it should remain in locked out position and likewise remain in the enabled position when the knob is pushed in.

Inside the OD, the lock out arm moves a cam that pushes the lockout ring into place when you pull the cable. When the cable knob is pushed in, springs internal to the OD push the lock ring back to the 'OD allowed' position. So although, yes there is a spring that pushes in this direction, the flat area of the lock out arm cam should hold it when you want to lock out.

My suggestion is two fold; If you can get under car and disconnect the cable from lock out arm:

1: Check to see how readily the arm pops out of Lock Out position.
2: Check to see whether the adjustment of the cable is correct to achieve full arm travel. If you are not fully moving the lock out arm to a hard stop, the internal cam may be not fully rotated in which case vibration could work it back to the unlocked out (allowed) position.

Hope this helps,
Pat
