I have a '62 Fury with a /6 and push button tranny. I plan on putting in a 413 in the next year or so and want to keep the push button tranny. Sounds like the best way is to get a '65 big block tranny as it will have the slip yoke tail section but those are hard to come by. I found a '64 Chrysler 300 with a 383 and push button tranny here local that I can get fairly cheap. If I go that route I believe the two shift cables on my car (/6) will operate the '64 big block tranny, correct? Also, I should be able to use the '64 Chrysler driveline, with ball and trunnion, and shorten it for my '62, correct?

if you have the Park lever on the dash should be a bolt in.
Bummer as I have a 64 cable shift w driveshaft I need to find a new home for

If the 300 has a console shifter those cables won't work on your push buttons, if it has the push buttons you should be good.
Those trannys are real sensitive to the adjustment of those cable shifters', one bolt hole can make it out of adjustment: shock:
I take the tranny pan off to adjust the shift cable, disconnect the retainer on the pin on the shift cable end that moves the arm that moves the manual valve in the valve body and then put the shifter arm in neutral and adjust the cable housing with the adjusting wheel so the pin drops perfectly into the hole in the shifter arm, perfectly every time
Have fun, take your time and look at it real hard before you start and make sure your very happy with the adjustment when you're done

The console shift vs pushbutton can be remedied. You need to swap the rooster comb, manual valve, and neutral safety switch from the /6 valve body. Simple swap.

IMO, it's easier to leave the console VB in place, use the PB cable and use the console adjustment procedure

This car is a bench seat car with dash mounted push button.

For clarification, my current /6 cables will work with the the '64 big block tranny, correct (same length, etc)?

John, wouldn't the larger groove in the cable allow for slop between the rooster comb and the cable itself? I've always been under the impression that the cable style, rooster comb, and manual valve must match .

I believe the rooster comb and manual valve are different between console shift and PB. The longer "groove" would cause problems one direction or the other when changing gears as that added slop would result in the manual valve not moving unless that groove is fully engaged in the different attaching arm.

See what Mr Kunkel has to say

The PB cable I recommended has the narrow groove and will fit properly in both the PB and console receivers. Again, the console/column adjustment procedure must be used when doing this.

So is the wider groove cable pictured normally used in a console shift car I'm just wondering what it's application was

doesn't the cable to rooster comb "adapter" have to match the cable used ? [wide groove vs narrow groove]
then the "adapter" pin od has to match the rooster comb hole id ? unless, of course, the od's of both adapter pins are the same, as well as the rooster comb's hole id's are the same.
i don't have anything of either, here to compare at the moment.

Yes, the wide groove is used only on console/column. The wide groove allows for some over-travel when placing the shifter in Park.

The "bullet" at the end of the cable is the same diameter for both and the narrow groove bullet will snap into the wide groove adapter but not vice versa.

Basically, the wide groove adapter has a spring at the bottom of its bore, the spring keeps the retaining wire pushed against one side of the groove during all operation until placed in Park then the slot allows the cable to over-travel slightly without kinking the cable. The shift cable performs no function in Park, it just shifts the shift valve into a dead space in the valve body casting...a secondary mechanism in the shifter operates the separate Park cable.

thank you

thank you John !
