Default Transmission interlock cable position

At one end of this cable assy there is a 'rubber' boot looking piece on the outer assy, does this end of the assy go to the transmission (TH400 on a '72) or the steering column? The diagrams in the AIM are not that clear and I haven't been able to find a picture on Google of anything but how the manual transmission hooks up.

Thanks

since the boot is to keep water and debris out of the cable I would say it connects to the transmission

Hi k,
I believe MW is right.
The end of the cable with the boot goes at the transmission.
Here's a couple of photos ... but of a 4-speed installation.
Regards,
Alan




And the rubber boot. For some weather protection?

Thanks for the replies, I was leaning toward installing it boot end to the transmission, but only wanted to do this once and knew someone would know. This forum is invaluable!

I have to ask this before I put on my Bubba pants. Background: at some time in the past I removed the interlock cable and bracket. I pushed the lever on the steering column as far up as it would go. Never had to wire it in place, it always stayed, and I was always able to operate the key lock as it should, and remove the key as I should.

Now I have reinstalled a new to me bracket and cable. I ran WD40 thru the cable shroud quite a bit and then the next day lubricated. I operated the cable many many times seeing to it that it was nice and workable; even bent the cable in a nice arc to make sure it was not binding.

Installed it and it is not pushing the stupid column lever up high enough to let me remove the key! Looking at the TH400 transmission end of the cable it appears that all the cable has moved into the shroud; in other words, the cable has moved all it can move, and is still not long enough or going far enough to push the lever all the way up. And at the column, the cable is straight, not kinked or anything like that. I am actually thinking about making a new inside cable. Sadly it only has to be about another 5/16" longer.

Any ideas on what to do to make the cable work? why it's not working?
No time to take pictures, if you need some I can do it tomorrow.

Thanks.

The plate that the upper end of the cable housing anchors to may have some adjustment. There are 2 nuts inside the car at the base of the column that secure the base of the column to that plate. Loosening those nuts and moving the plate that anchors the cable housing may help.

There is some adjustment in the location of the plate that holds the cable.
The fixed plate on the column (inside the car) is slotted and the firewall has a huge amount of clearance.

Hopefully you can get the adjustment you need that way

gawd I hate this car right. Can't move bracket, can't stretch cable, sure glad don't need this =/*&:!ing system in order to drive car. Then again, glad I'm smart enough to not drive it in my present state of mind. The distance between column lever and where cable outer shielding is the problem, have no choice but to spend MORE $ on new stupid cable damnit janet.

thanks for listening and the suggestions

Patience, patience, patience. Easy to say, harder at times to have. Hang in there.
Look on youtube for some help or Willcox or Corvette Central Tech section.

I am installing the last one, the Automatic Transmission Steering Column Lock Cable. I have installed it at least twice now. The problem is that when it is installed, the distance between where the cable shroud attaches (with a mickey mouse clip) to the bracket that is installed on the firewall below the steering column and the lever where the cable hooks on, is too far, not allowing the cable to attach. Probably only a quarter inch short. (See picture) The red lines on the right is where the cable is too short. The red line on the left is just indicating where the cable end fitting is and you can see how far it is from the post on the column lever....

I tried loosening that bracket on the firewall and forcing it up, so that it might move the cable and cable shroud closer to the lever but that did not work. I was going to try and remove the cable ends and use them to make a new cable that was longer, but not sure how those cable fittings are attached to the wire rope. Thought they might have been swedged and soldered but using heat did not allow me to remove the fittings.

I'm surprised you couldn't get the bracket to move, it's really slotted, the thing maybe wouldn't lift as the column is fixed but it should allow for the bracket to rotate somewhat.

Hard to get to as everything is in the way but here's where mine sits right now in park, see if this helps





4-3/16" to the middle of the pin. Rule sitting on the bracket off the corner rad (best I could) and not on the clip

Thanks M, I'll measure my similar distance and see how we match up tomorrow.

You might consider what DUB mentioned ( I took mine out for a rebuild but am not a the point to install ) seems it may be easier working backwards. BTW, I wouldn't reconfigure the cable ( cut/solder ) it will fit.
