I know it's probably wishful thinking, but does anyone know if the typical Ford speedometer cable has the same end on it as the '62-'65 A727 version? They look almost identical, and the Ford version is a lot cheaper than trying to get one sold for a Mopar.

I think you are asking about the transmission side, and I am not sure of that. They do look similar and I would not be surprised if they are interchangeable. Stewart Warner and a few other companies supplied a lot of those parts to the automakers.

If you mean the dashboard end, I can confirm that a Ford speedometer cable will thread right up to a '57 Plymouth speedometer and it will work.

Yeah, I am talking about the trans end. The gauge end is 5/8-18 on the Ford, and I think that's the same as the Chrysler too. I will measure it for sure. The thing is I can get the cable for a Mopar for $150, or $20 for a Ford. If they have the same ends on them, why the big difference in price? I am going to take a chance and purchase the Ford cable to compare it. Hopefully I have the speedometer cable on the other push button trans I have. If not, I may just try and run it with the Ford version and see what happens.

I can see one visual difference in looking at the pictures. The very end of the Mopar version has a reduced diameter on it, and the Ford version doesn't. That may be required to seat into the plastic gear, and the gears are definitely different between the two. If that is a problem though, I am thinking I can just carefully cut it down with a bench grinder to get the diameter I need on it. I will remove the cable inside first of course. I should get the Ford cable by the end of next week so I will post my findings.

Yep, the reduced diameter is for a seal inside the Mopar pinion. The Ford is different.

I am guessing that seal prevents oil from going up the cable sheath, although, when I looked at my gear, the seal is very shallow; much shallower than the extension on the shaft.

I finally received the Ford cable and I relay the bad news for everyone. The transmission hole is .965" diameter and the Ford end is .875". This small diameter means that the O-ring that is supposed to seal on the trans doesn't even touch the walls of the hole. The insert is just too small. It would have been really nice if they would have used the same dimensions, but like I said at the beginning.....wishful thinking. So there goes another $150 for a stupid speedometer cable.

Would it be possible to find/fabricate a bushing or spacer to allow proper fitment?

The small difference might require some ingenuity - say a thin plastic or metal sleeve to support the cable end bushing, and changing the o-ring to a larger diameter lip-type seal might work . . .

From what you've posted it seems like the overall fitment is pretty close, it would be a shame to have it not work out.

Open up the cable crimped part and change just that part instead. You can cut it open with a Dremel - fit the crimping to the new cable and sequre with shring tubing (with glue inside.

Sometimes it's even possible to screw out the crimped part from the housing.

I've fixed several ones this way and it works.

Another question: I just noticed that my small block push button 727 doesn't have any cooler lines on it! Is that normal? Did they all come like that or is that some unique application? Can I convert it to route the lines to the radiator? There seems to be 2 small plugs at the right/front side of the trans, shown in the picture below. They seem too small to fit cooling lines, but maybe they are? The left side has 2 more, but I think at least some of them are the band adjusters. The cooling lines come out on the left side on the later 727, but I don't know where they would be on a push button trans.

The plugs shown are for pressure testing, the cooler fittings and lines are on the other side of the transmission; front fitting is out to the cooler and the rear is return.

Thanks a lot John. I found this picture of a push button trans, and I am assuming the red caps are the locations of the cooler lines. I still don't understand why they are plugged off to begin with. I am wondering how bad it would be to run it like that, but I am definitely going to put lines in.

Running with the cooler ports plugged is death to the transmission, the cooler circuit supplies lubrication for the internal parts on the mainshaft.

That's what I would have thought too. I hope the trans is OK, but maybe they plugged it just to prevent it from leaking while out of the car. I have one line routed up now. Once I get the other done, I will try driving with it and see how it goes.
