so i have a 09 Sahara JK and i've been driving it for a while
now and every once and a while when i'm stopped and then
i go to take of in first around 1500 rpm it gets like kicked out of
first gear.? the first time it scared the shit out of me and then it
didnt do it for a bit and then it will do it once and a while. is it cuz
i'm fully putting it all the way into first or what? can someone help me?

thanks

 

Make sure you are all the way engaged in gear. (of course). Second maybe a upgraded fluid would help the situation. I've run royal purple syncromax since 1000 miles, never had that issue myself..

 

so change the transmission fluid

 

I've seen on the forums that, that has worked for some people. So that is the best I can suggest. I changed all my fluids at 1,000miles to Synthetic and have never had a pop out, so I can't give you a comparison.

 

how much did it cost you to do ur tranny? cuz i already changed my oil to
synthetic. did u change ur diff fluid?

 

i have royal purple in the t-case, trans and mobil1 in the front and rear axles. Probably spent around $80 in fluid. Did it all myself of course.

 

ok thanks a lot. how often do you
change everything?

 

If it is fully in gear, it should NOT pop out of gear regardless of the fluid you are running. Does it always do it? Is it consistent?

This is a sign of serious problems in the syncros. Take it in and have it checked. It should still be under warranty, right?

I would think an overhaul is in order, but have the experts check it out. If the dealer is a PITA, take it to Aamco or something to get an opinion.

 

It has happened to alot of people..it happens to me when it is cold out..it is the lower shift boot being alittle tight and when cold it is stiff so it pops it out of gear..I'm used to it, but you could ask the dealer to look at it.

 

OK I understand if the shifter boot is in the way, but how would fluid fix that? He also says it happens after he has been driving a while.

Like I said, unless it is not all the way in gear (which I have done about 3 times), I think it is a problem. If it only pops out of gear when torque is applied, and everything is all warmed up, I read a problem.

But hey, if there is a simple solution, then I am all for it.
