I bought a YJ a couple years ago and it had a 4 spd Atlas in it. The guy I bought it from just had it installed a few months before I bought it. Ever since I've had it I have had a hard time shifting. I realize that it is suppose to be easier to shift while your moving, but there are times I have to stop, put my tranny in neutral or even shut my motor off before I can shift it. I have called advanced adapters and they just say sometimes they are difficult to shift. There has got to be a way to adjust it some how. Anybody have any experience with this problem in there atlas? Thx
