70 scj transmission shifter issues
« on: April 30, 2012, 01:05:44 PM »
I have never owned an automatic car, does anyone have pics/advice for installation, seems like my kickdown is awful tight, i had to make my own bushings, maybe have to reem out a little more.  I am not positive it is the correct kickdown.

Do you have the correct spacer plate and intake?
Changing the height throws things off.
A newer Holley 4150 series won't make a difference as far as I know.

I have the wrong kickdown and shifter linkage also. Maybe thats why it was binding.

$150 will get you a repro here:

Check your carb numbers just to be safe:

I have a 70 428 auto, non-a/c carb, but it's in pieces.
I'll have to see if it would make for a helpful pic.

shifter works thanks to the right parts from JD Larsen allclassicmustang, NOS rod and connecting parts. That makes me feel better. Got a BS kickdown on ebay ordered on from MrBill at mansfield, sure i will be happy then too. My carb is the right carb for 70 scj auto

If no one beats me to it, I can post some pics tomorrow night. what do you need pics of , the trans end, or the carb end ?? I have an absolutley unmessed with 70 C6 from a 34K mile scj car that I parted out in the early 1980's sitting on a shelf, I'm guessing that you need a pic of the trans end.. IF my memory serves me correctly, the bolt on kick down lever on the trans moves the kickdown rod farther away from the trans than the earlier lever, I'll try and get a pic of both parts..   John

 UPDATE>>ACTUALLY....  Look at the last pic posted here.... http://www.428cobrajet.org/id-kickdown.html  This shows the 70 lever well, If you have the 69 lever, the kickdown will bind  up..

I was thinking about that pipe plug sticking out, so how about this as an alternative to bending any parts to clear it.
I'd go with brass or stainless so it won't rust in there.

thats why i want to see a picture of how it is supposed to look under there, the plug is correct that is installed now, for some reason when i see what it is supposed to look like it is easier to make it right
