high clutch and gear rejection

please forgive me if another thread of the same topic has been started... what a vast expanse of topics to look through!

i've had the 2012 since the 6th of october... and my service apt is scheduled for next thursday.. but in the interim, has anyone with the pentastar experienced the following??

1) the clutch engages very high... almost at the top. normal?

2) 3rd gear is kind of "crunchy" at times when engaged... not smooth like the other gears

3) two cold mornings in a row, while accelerating... two second after i put her in fourth, the shifter kicks out of gear into neutral?! (not normal!)

-thanks

High engagement is normal.

The manual actually makes it clear of difficulty shifting when cold.

As far as popping out of gear, not normal but common. I believe there is a TSB for replacing the shift boot on earlier JK's, not sure what that does ??
I just bought my 07 and have not had any shifting issues or popping out of gear.

There is a lot of threads on some of your problems.

Edit : I obviously don't have that engine but the 6speed is the same.

thanks for the feedback... i've gotten used to the high clutch, all my previous vehicles were low to mid clutch... so it was an adjustment to say the least

this morning was pretty cold, and she didn't pop out of gear, so i'm thinking maybe i wasn't completely engaging the gear or perhaps the boot was bunched up so it didn't fully engage.. still gonna get it checked out though.

that said, i love this engine/jeep!!!

Yeah, "crunchiness" is fairly common in comps weather. Experiment with exactly how you push/pull it into the gear in question. Mine use to crunch going cold into second, but I eventually learned how to pull it such that it avoided the crunch.

Jumping out of gear ("JOG") is a pretty big problem that a significant number of manual JKs have had for years. It's worse in the cold. I'm not sure jeep's ever really fixed it--it was always approached vehicle by vehicle. If it persists, document it by making a video on a camera phone and take it back to the dealer as soon as possible.

this is, in fact, my first rear-drive vehicle in nearly 9 years. And regrettably, my first Jeep.

Front driver four-cylinder manuals, and Jeeps -are completely different animals. Beneith a Jeep's manual shifter-knob lies segways of steel and direct linckage to the transmission. where numbness may be a road-feel staple, JKM(manuals: )~ make up for this with tranny-charm.

The whole reason i never buy automatics is the appeal of becoming "one" with the vehicle. there's not always pure enjoyment, but for the many moments there are, it's completely worth it.

i wonder if 2 live axles plays a factor? There's certainly vibrations to be felt in the shifter.. someone once said "my shifter knob has death wobble"
-all that shaking around maybe prevents the gates full engagement when cold?

[anyone else initally scared of 6th?... a friend said -"no, reverse is locked out when at forward speed" ...well... i disagree]

This is because the shifter is directly mated to the tranny. When you have drivetrain movement from torque the shifter will move as well. On front wheel drive cars the shifter is usually cable operated and completely detached from the tranny itself.

Shifter movement/vibration is normal on most rear wheel drive vehicles. With the exception of the 97-latest corvettes and the like

Also since the clutch grabs high it could be driver error the shifter popped out of gear. If you foot is slightly on the clutch pedal its going to slip or disengage the clutch. Just my $.02

Agree. My new to me 07 has never popped out. I was ready for it especially being an early Jk. With my Tj I could rest my foot on the clutch with no issues. Jk hell no--it disengages/engages near the top. Resting my foot on it is a huge nono.
Shifting my Jk is a whole different experience.

i certainly wouldn't rule out user-error.. i'm still getting used to it all (and LOVING IT!! had the partial roof off today, life IS good)

the hill start assist is something to get used to (where my stalls were occurring).. definitely takes more gas to release the HSA, than in a normal pull outs.
