63 New Yorker Push Button Torqueflite Cable Questions

[aaron72]

Looking for a bit of a sanity check on the cables for my transmission and making sure I've tracked the routing correctly.

In the pictures below, do I have the cables correctly identified as:

1. Gear selector cable
2. Parking lever cable
3. Speedometer cable

I am trying to track down a transmission fluid leak that I thought was the pan, but after replacing the pan and gasket, it continues and I believe I've tracked it down to cable 3 which I'm pretty sure is the speedometer cable.

I have cleaned up all of the cables and where they connect to the transmission so that I will have a better visual when I go back under to try to identify the source.

When looking at the speedometer cable (3), it is routed so it is sitting on the torsion bar base on the drivers side. There are drips coming from the boot for that torsion bar as well as from this cable. When looking at the cable after lifting it off of the base for the bar, there is a bit of a groove worn in the cable.

Does the speedometer cable carry transmission fluid internally. I'm wondering if the groove in this cable is where the fluid is coming from, or if it's coming from the connection at the transmission and then running down the cable as it goes downward towards the torsion bar before it goes back up through the firewall.

Any help in regards to verifying my identification of the cables is correct, along with if it's possible the speedometer cable can leak fluid from a hole worn in it would be much appreciated.

Your cable identification is correct.The speedometer cable does not carry transmission fluid "per se." However, fluid can get into the cable. Also, both the speedometer cable and the gear selector have an O ring to seal them when pushed into the transmission. correct. You remove the shifter be careful of turning the dial, actually not turning the dial that bolts to the transmission. That is the adjustment for pushbutton operation. Turning may make your car start in gear or be in a different gear than what is selected.

Thank you for the feedback.

I'm pretty sure the seal that goes in between the speedometer pinion gear and the speedometer cable has failed and transmission fluid is actually getting into the cable and leaking out of the worn area.

I'll be purchasing a new cable and pinion gear with the seals and will do the replacement of those this Winter.

I'm not planning to fuss with the gear selector cable, but thanks for the heads up.
