Problem shifting into Reverse (manual)

I have a 2012 JK manual 2DR and have a problem putting it into reverse.

When shifting into Reverse if you put the clutch in and shift it'll feel as though it's in reverse but when you disengage the clutch it grinds like crazy.

If you push the shifter back into Reverse as you release the clutch slowly it will "fall" into reverse and stay there, I've never had it pop out.

Any thoughts? Someone told me that my linkage needs adjustment but IDK WTF that means.

That's definitely not right. I'd have the dealer or mechanic check it out.

It's not normal. It's supposed to go over and down into reverse with no problem. What you can try is engage the clutch, shift into first and then bring the shifter down, through neutral, and over and down into reverse to see if it engages easier. I'd be surprised if it was the linkage. It's possible that, if you have high mileage, the clutch is causing the problem. However, if it's only grinding going into reverse and not first there could be another issue.

This is more for my personal knowledge than anything - but, why does shifting in to 1st and then straight to reverse make it easier? Or, supposed to make it easier?

Mine was hard to get into reverse until I replaced the middle shift boot. I replaced it because it clicked every time I hit a bump in 2,4, and 6, but it also made shifting into reverse easier and got rid of a lot of vibration on the gear shift.

Probably the best $35 mod I've ever done.

My 2012 unlimited does the exact same thing. It has around 50,000 miles. I bought it with 40,000 and it's always been the normal. When shifting into reverse, I always just keep my hand on the shifter that way it stays in gear. It's actually the shifter just jumping out of gear, causing it to grind. I had someone explain it to me, he said it had to do with the type of gear, that if it doesn't grab right, it'll slip out. No idea if that's right or not. Never worried myself with it, but i'd be interested in knowing if something is actually wrong with it.

Honestly, it never bothered me either. In fact I got so used to it I never even thought about it... until I let someone borrow the Jeep and he was pretty worked up about it.

With an AX15 trans. that's in my YJ when the clutch was starting to go it made it easier to shift into reverse because it engaged the synchro from first to reverse. I don't know if that will help with a JK because mine shifts properly, but I'm curious to see if that will help. The problem could also be as simple as the inner shift boot is causing the shifter to hang up. It should not slip or jump out of gear. If it does the problem has to be further diagnosed.

Mine does the same thing, but it only does it when you don't pull back far enough to go into reverse.
Sometimes it takes more force to get it to go into reverse for whatever reason and I just made a habit of using more force and to double check when in doubt to avoid that grinding

My 2017 was popping out of reverse. It was the shift tower. A weak spring for a detent. Anyways while I was searching for what was causing it, I think I saw a TSB for a 2012. You should call FCA and see if there was and might be able to get it fixed under TSB recall

Were you able to get yours fixed?

Mine has done this pop out of reverse BS since it was brand new...but lately 2nd going into 3rd is not smooth. The best way I can describe it is like I'm navigating through marbles to get it into gear. The whole thing just feels "loose". Problem is I'm in Germany so I don't have many warranty work options.

Unhappy Jeep Wrangler 2016 Manual Transmission Problem

Hello fellow jeep owners ,

This is my first wrangler i have ever owned and have had it for a little bit over a year now. Everything is going great but recently i discovered 2 small issues with my manual transmission....
1. When shifting into reverse, sometimes i hear a knocking sound and can feel the transmission engaging with the engine slightly.
2. When the shift lever is left is neutral i can hear a small rattling sound, but if i slightly move the lever down into the 4rth gear position(not engaged), the rattling goes away.
If anyone has ever encountered one of these issues, please let me know if they are normal or not.

Thank you !!!

Hi Mohave-Hound,

My 15 has been doing that since new. With 23K miles on trail in Aug it got really bad. Took it to the dealer. They tore into the TC and discovered multiple worn syncros, and bent shift forks. I have been driving a clutch for a LONG time so this isn't driver error.
Warranty covered the complete rebuild of the TC. It now shifts like butter and doesn't kick out of rev or grind. I am still going to get the B&M Shifter as I think it will clean up the throw a bit.


For those of you that are grinding or popping in rev go get it checked. Especially if you wheel frequently.
