Stiffness in shifting lever for transaxel

1995 Buick Regal, v6, excellent condition.

Shift lever very stiff and difficult to move. Eases a little when engine is warm.

No vivible kinks, crimps or bends. Permanently lubricated. Do the cables stiffen with age and need replacement or is it an indication of large problem in transaxel?

Two things come to mind. Firstly, what I find most common, is that over the years you can get sticky stuff into the collar on the steering column which can gum up the motion and be really difficult to clean out. Another possiblity is that the engine/transaxle mounts are sagging with age and the transaxle isn’t in the exact same position as it once was, causing the shift linkage to operate improperly. The “dogbone” mount that attaches the engine to the radiator bracket up front is very prone to sagging on these cars and is also pretty easy to replace.

Thanks, will check it out.

Another thing to check is stiff/worn park-neutral safety switch.

This is mounted on the transaxle shaft that the shift linkage connects to. Sometimes these switches become stiff to operate. Especially when the weather turns cold.
