Hey Chuck (in case you didn't know who I ment)

I was recently on the phone with an owner in San Antonio (TX) and he allowed that he cannot even budge the shift level.
He is not a proficient wrench (by his own judgement) but has access to a good man. He is going to drive his coach to the shop by using a reach rod to the transmission.

It is my guess that this mechanic will disconnect the cable at the lower steering column to separate the issues, but if it is in the column lock, how big an issue is this likely to be?? I have been into the manuals and can't find any discussion of the column lock at all.

I did give him your name as some he or the mechanic could call if help is needed.
(He also said that he might like to go to an updated steering column.)

Matt

Matt, the "column" lock only locks the steering wheel tension spring holes with the little pin pushed by the spring on the back side of the key tumbler. Y If he can turn the key and wheel more than likely the cable is the problem. He should be able to pull the cotter pin and take the cable loose from the lower column and tell which.

Matt, if it is in the column it could be the knuckle joint lower housing broke or the shift tower housing. The lower knuckle is interchangeable with the new type, only difference is the cast on tab for the dimmer Rod. The lower shift tower can be used but you will need to do some grinding on the inside.

Hi Matt, thanks for posting this, and Chuck thanks for the reply.

I just removed the shift cable cotter pin at the column. The shift lever moves freely with the cable disconnected. I did notice that the shift indicator is no longer moving along with the shift lever. Does the indicator need the cable to be connected, or as I suspect, is this a separate problem? Chuck, if I need to take the column apart to repair the indicator then I may need your advice again.

Matt, I've ordered a new cable, but don't expect it to be here before your SA visit. It looks easy enough for me to replace though.

Thanks again,
Steve

The dash indicator has a small spring loaded cable that goes from the indicator across a stud pin behind the panel, to the column. It is attached with a Phillips screw on the lower column at the dash. It is in a slotted hole and is adjustable. I have soaked cables with penetrating oil and got it back working.

Separate problem. The cable for the indicator is clipped to the shift bowl on steering column.
