Can someone please tell me if the seal on the Ultramatic shift rod can be replaced from outside without removing the pan, transmission in the car. Also, is this a seal which could be obtained locally, or does it need to be ordered from one of our parts suppliers. Thanks,

You have to cut a hole in the frame or drop the trans. Pan must come off either way and you need to remove the shifter shaft assembly. Then pry out the old seal and replace.

Seal is an SKF 5569 but you will need to buy a new pan gasket anyway.

Thanks.

HPH is correct in describing the proper way to change the throttle or shift shaft seal but on some transmission cases the machined bores the seals press into is deep enough to add a second seal leaving the original in place. If your trans has the deeper bores remove the lever and clean the bore and shaft well so you can check for any gouges or other damage where the lip of the new seal will ride. As long as the bore and shaft is smooth and otherwise in good condition that second seal addition will usually control a leak and can get you by until a time you need to remove the trans for something else. Of course, it is also possible this quick fix has already been done and the bore is full. In that case it would probably be necessary to follow the procedure to get the old seals out so you could do the job correctly.

On my 53 I was able to remove and replace the seal without cutting a hole, removing the transmission or shaft, which was a little unnerving as I knew once I damaged the seal I was committed. My real issue is the shaft is not smooth, so it still leaks.

I'm just going to live with it for now. (I think primarily it leaks when the car is parked, not when the car is running and the torque converter is full.)

My transmission is working well, but one day I may drop it and put a rebuild kit in it. As far as I know it's never been rebuilt, but don't know for sure. It's not that expensive if you can do it yourself.
