67 Auto trans.

[SFcarbuff]

Is the 67 GT350 auto trans the same as the 66's with the better servo?  Looking at an auto car to buy.  Thanks

   The '67 C4  uses a "select shift" valve body so it's pattern is D,2,1 instead of dot ( 2nd and high) "green dot" ( all three gears) and L for low only. The code for the transmission is PEE-K and the valvebody is unique compared to other '67 automatics which also shared the "new" shift pattern. The valvebody is the only difference between earlier K code C4s.

Also the shifter mechanism is unique and made different on a a 67 automatic Shelby as it allows you to shift different compared to a regular Mustang.

  Bob, in the "old forum" you posted a template for that.  Could you post it here on the new forum?

Rod I don't remember ever posting a template of the different added detent but maybe I did. I will try to remember to take a picture of one on the shelf and post. I have ended up with two nice used 67 Shelby shifters and I never thought I would have even one.

  Bob ,
     I thought it was you or Jeff that posted it. I was going to check my DSO sheets to see it they call out a "special" shifter assembly ( as in Ford doing the modification) or if SAI did it. I guess I forgot to do that as I still don't know the answer.

Here are three pictures I posted to that older thread and somewhere else that show the added indexed plate, the threaded hole in the arm and the shaft/insert that was placed in the threaded hole . Hope these help







There were a number of other examples that I thought I had grabbed but they are likely in one of the directories unlabeled - with a few hundred more I need to get to

Pulled one set of sheets for 350's with autos and it showed (on paper that the shifter and housing (C7WA-7C453-D) was "deleted" but no replacement was listed with the items to be installed. Sheets were from Jan. Same pattern as found on a later group of 350's with autos

On another (set of 500's) it shows the shifter and housing being installed and noted as - supplier by Shelby America. Sheets were from April/May. Another set from a later group shows a substitution of shifter and housings without the "supplied by" notation. Maybe by that time the comment was not longer needed. Who knows. plenty of spelling and little errors in the sheets as they seem to be a "living" document at the time

Just a quick look at the add/delete sheets from four different groups of cars

[67_1183]

DSO 84-2566, the group that #1183 is part of shows the following:

ITEMS TO BE DELETED: C7WA-7C453-D  RPO  Housing & Lever Assy - Trans Control Selector

ITEMS TO BE INSTALLED: C7ZX-7C453-A       Housing & Lever Assy - Trans Control Selector

  I've seen that little threaded gizmo in a McMaster-Carr hardware catalog.

I'm curious as to what the modifications/additions incorporated in the C7ZX version were supposed to accomplish (?).

Great Info   The car I am looking at is correct.  Thanks

Here are some pics that I posted on the old forum ...

rbarkley: Ok, but but's template was better in that you could make the detent pattern, exact.

J Speegle: can you guess the threads.  It looks either 5/16 X 25, or 1/4 X 20.  What say you?

Old guy: it puts a little tension on the moveable part of the shift handle so you don't over-move it (to up-shift) while accelerating away from some Corvette.
