Just like anything mechanical, though, in the hands of some it can and will be screwed up. I'll take a stick over an auto any day. Only issue I ever had with the Jeep tranny was the long throw to reverse, but they fixed that by 2010.
Had a 68 Scout in Viet Nam for a while as my personal vehicle. It was a lot more comfortable than the M151 (military jeep), especially when it rained since it had a top. It went everywhere that the M151's did. Only had one problem with it when it got stuck in low range once. Had to get a BIG sergeant to get in the back seat and repeatedly kick the transfer case lever to get it out. After that, it was fine.

I agree. When I bought my 13' I went out of my way to get a manual. That's all I wanted. But it wasn't worth me paying out if pocket for something that was a bad design. Miss the old CJ days when the manuals would take a beating and ask for more.

Since I can't hear your I would guess they are all this way. Everything in the Jeep is built for strength. It may not be as tight as your other vehicle but it will take much more of a beating.

I would suggest talking to your dealer about your concerns and maybe taking another one for a test drive to compare.

I had a 78 Bronco with the manual tranny and it was loose and a long throw, but it was one of the toughest transmissions I ever had. They used the New Standard transmission which, back then, was the same one that the Army used, granny gear and all. Never had a single problem with it, though I did break the transfer case while going down a mountain in Arizona - lost the ability to keep it in 4L unless I held the transfer case lever back. Luckily, I had a passenger to do that for me, but the transmission itself was fine and I beat that poor old truck to death.

Re: 3.6L Pentastar ?

Thanks Wingit. I am taking it to the dealer. I am going to test drive one of theirs for a comparison and go from there. I have owned quite a few standards; Jeep, VW, Ford, and Nissan and all of them were tighter. There is also a lag between clutch and engage with like universal clicks. The clicks are only there after shifting. This Rubicon may need some help. The motor is not running smooth either. We shall see what the dealer says. I wish I had more faith in this dealer but am stuck with them. Thanks for responding.

The clicks could indicate a bad throwout bearing in the clutch.

Re: 3.6L Pentastar ?

I hope we get to the bottom of this Mike. Thanks for responding. I know some parts are bad even new. Hard to believe but true. The dealer here will be squirming when I bring this warranty problem to him.

Re: 3.6L Pentastar ?

We're a 2 Jeep household, wife's DD a 2013 JKU Sahara with 28k miles and mine a 2014 JK Polar with 22k miles and not a tick or engine problem out of either one. We did have the wrong coolant issue on her Sahara and they replaced the entire cooling system because of that. Otherwise, nothing but oil changes!!!!

Hum... I have a 2008 JKU with manual since Oct 07. With 90k plus it is fine. It is clunky but my two CJ 7s were also

Re: 3.6L Pentastar ?

Any of you guys with the manuals, try changing the fluids and see if a better fluid might improve the shift quality?

Re: 3.6L Pentastar ?

I'd think twice about randomly changing transmission fluids. The factory fluids are specified, not only for their lubricity and longevity, but also for their influence on the function of the blocker (synchronizer) rings. You can very easily screw up a set if blockers by putting in a fluid that lacks the proper friction modifiers. Take it to the dealer after that and you will be told it was abuse and therefore...no warranty. I believe I can say this with some degree of authority. I'm a former manual transmission engineer from NVG. You just don't go dumping in a new fluid unless you are willing to face up to the potential consequences.

Concerning the current Daimler six speed, I would give it a 9.5 for noise and a 7.0 for shift quality. Very little clunk and rattle, a function of clutch disk damping as well as gear tooth clearances, drag, etc. i'm happy with mine in my '15 WW.

Re: 3.6L Pentastar ?

I have an early model 07 Rubicon with 6spd manual…never had a trans issue with it ever, and I've wheeled it hard and drove it hard since day one….only about 90,000miles on it, and serviced the trans once around 80k miles…Ive always done all my own servicing with OEM replacement fluids for engine and trans…(except diffs)…when I dropped the original oil it came out completely clear almost like it was brand new…..

Also these are jeep wranglers….not known to be butter smooth and tight….id say every other vehicle shifts better than one….lol.
