Thread: wiring switch pitch?

    wiring switch pitch?

    I have a 1964 LeSabre with the original 300 and ST300 trans. I was of the understanding that it should have the switch pitch torque convertor, but upon attempting to find a way to set up its activation (dash pot is on the intake, but no switch), I was only able to find 1 male electrical connection on the trans. 1 of the 2 wires coming from the kickdown switch was attached to this connection. The kickdown function works, so am I missing another spot on the trans where the wire for the switch pitch is supposed to go? If so, where might it be?

    I have tried to read up about the switch pitch as much as possible. I read that there should be 2 connections on the trans., a horizontal 1 for the switch pitch and a vertical 1 for the kickdown, but there is only a horizontal 1 with the kickdown wire attached.

    I would love to get my switch pitch up and running, but am now wondering if I even have the switch pitch feature at all!

    Thanks in advance for any help or info.

    Have a look at the '66 shop manual in the Reference - Library section of the site. It covers the ST300. The manual only has B&W wiring, but if you look in the Years, 66, you will find color wiring diagrams.

    Smile Maybe some more info...

    I have a '64 LeSabre with the 300 4 barrel and 2-speed and I'm gonna see what transmission it has. I seem to recall it has a solenoid mounted in the throttle linkage.
    Meanwhile, I found 2 references that may help you (us?):

    I love my LeSabre and it's drivetrain really performs for such a large car!

    Hi, I'd say you may not have the trans you think...
    Here's a pic of what your carb linkage/wiring should look like if you have a s/p ST300...
    As Bob said have a look at the 66' manual to identify your trans....
    Hope pic helps...

    This is what a NON-switch pitch might look like...

    Took a picture of my stock setup and only 2 wires from a single switch are present. This would mean I have just a regular ST300, not S-P.


    HTH!
