Fellow Maverick enthusiasts,
Recently when I upgraded my '76 Maverick from the I6-250 with a leaky C4 automatic, I pulled the C4S (that is eeesss after the C4) from my donor '73 Maverick. My question is: Where do the vacuum lines for the modulator on the C4S go to? Remember that my origional C4 did not have these so I am at a loss to where they go. .................... Tracey, I think in your question, you have the C4S and C4 switched. ..The C4S does not use a vacuum modulator. These are manuel conrolled transmissions that are the same as a C4 but have a manuel internal valve body. ..The C4 can use either a single or a double port modulator depending on the year and if there were emmission controls involved. ..On the single port, just go to mainifold vacuum. ..On the two port, one line goes to the manifold vacuum, the other would go to a vacuum gating valve that is part of an emmissions system I don't think you have so no place to go with one of the lines. ..If you change to a single port modulator and plumb to manifold vacuum, the trans should shift ok. |
