Important Information
Trans MUST have a vacuum modulator hookup. Always connect the manifold vacuum
to the modulator. Even a Low vacuum is better than none! Kick-down linkage is
adjusted so you can get a 3-2 downshift comfortably with the accelerator pedal
near the floorModulator Adjustment: Adjustable modulators have a screw visible
when you remove the vacuum hose. No more than 3 turns in either direction from
the factory starting point. Better to be a little early than late! Saves gas,
has longer trans life, and has better performance overall. Make 1 change and
road test.
For earlier shifts: Turn the screw counterclockwise 1 turn at a time or
you can also use a shorter modulator pin. For later shifts: Turn clockwise 1
turn at a time, or you can use a longer modulator pin.
If trans has a brief bind-up on 1-2 shift:
Back off the rear band adjustment one additional turn.
Trans Operation:
P R N D2 D1 L
- D2 Starts on the 2nd. Shifts to 3rd Kicks-down to 2nd but not to first.
- D1 Starts in 1st and shifts 1-2 & 2-3 Kicks-down to 2nd or 1st-speed dependent.
- L Starts off and stays in Low [1st]
Adjusting Bands: Apply a little sealant to the back side of the locknut to prevent leaks. Hold adjuster while tightening locknut after adjusting Bands.
