Then 4H IS next to neutral.....No harm at looking at the engine mounts. Centered? If the Jeep were rear ended the engine could be rearward, putting that TC linkage toward Neutral. (I broke my mounts and the engine is forward from snapping a chain too hard pulling a log). Low is on the edge of the through now.
Idk either, nothing looks like it was rear ended, engine's centered and I don't have any bad vibes while driving I take it up to 75 no problem.

Do you have to loosen the bolt that's on the bar going (into?) the case? If yes, then no I haven't.

Is there a certain length or space it needs to be in or just to where low will engage firmly?

Quick question. When you shift the t-case into low using just the link in the pic, should the flat bar be close to the case or farther away from it?

Figured it out and it was kind of the above! Try $.16 worth of coins stuck in the shiftgate.

Wow. Not many "fixes" leave you with more money than you began with.

Well done sir!

Really and truly I should have thought of it first because I had the problem of it not coming out of 4hi cause a quarter had gotten stuck in front of the shifter. And here I though I got all of the loose change out!
