Question shifting from 4lo to 4hi.

I have a 1999 tj wrangler automatic. When i shift from 2lo to 4lo, it grinds. I get stuck in the neutral position and cant go anywhere without it grinding. It also will slip out of gear after a few seconds unless you apply upward pressure against the shifter...Any sugestions or such!?

From 2Lo to 4Lo? You have Tera's 2Lo kit installed?

do you have a 2low conversion or is it just a typo, your title said 4lo to 4hi and in message you put 2lo to 4lo just trying to get it straight

For 4hi to 4Lo, make sure your automatic transmission is in Neutral and you are not moving. 2hi to 4hi can be on the fly up to 55mph, but 4 hi to 4lo and 4 lo back to 4 hi must be with the transmission in neutral and the vehicle not moving. Sometimes you may have to put it back into 4hi, back into drive or reverse, move half a foot or so, and try again, but the trans MUST be in neutral and vehicle moving less than 3mph to go to and from 4lo.

Popping out of 4Lo usually indicates the shift mechanism has slipped out of adjustment. The rod to the t-case normally pulls out a little if the bolt that holds it in place loosens which will prevent it from shifting all the way into 4Lo. It's easily adjusted back where it should be once you get underneath and see how it works with someone shifting it from the top.

Grinding while shifting into 4Hi is a little more troubling. Your Jeep didn't by any chance come with manual hubs up front did it? Or is it a YJ?

as stated above make sure your tranny is in N and you are not going more than 3mph. Do you have a body lift?? your shift linkage might be out of alignment/adjustment. Mine would pop out of 4lo after my body lift until I adjusted my T-case linkage. It has an adjustment slider bar you can try. Could of came loose or shifted. Mild grinding is normal I think. Also make sure you are pulling the T-Case lever toward your leg as you pull up to engage 4lo after N on T-case. good luck!

no, it is a tj, and it is all automatic. But i will definetely check that out about the slipping out of 4lo. I have just been trying to troubleshoot the whole thing because it jsut feels nasty when you are leaving 4lo, and when you are in the neutral stage, you cant really go back to 4lo or to 4hi without grinding.....It seems fine leaving 2hi and going to 4hi or 4lo, but leaving 4lo is where the problem seems to lie.....and I cant put it in 4lo if i am at a stand still without it grinding really badly.....
