My first jeep had an issue like this. Mine had the bushings worn out. I'd check your transmount. You might be able to get it working if you adjust the linkage. I ended up just going with the direct link replacement style linkage on mine, the stock stuff is was over thought.

I am very seriously considering a replacement item that is advertised on ebay about $40, all steel, threaded rod adjustment, I think it just bolts on, and eliminates slop from those green poly bushes, which are very hard, but do wear. Mine does not always engage all selections easily and I want to overcome this.

The alternative would be replace the green bushes

a 10" adjustable spanner fits nicely over the tx case selector lever from below, so you can use that to click it all the way (and aid in the adjustment needed)...but be warned, the adjustment process is not straight forward with worn bushes, one of my rods also needed taking out, flatten in vice, file damaged surface etc
