Hey guys

Heard a bunch of talk that the manual trannys coming right out of the factory are low on fluid. Any truth to this or another forum myth ?

Just ordered a new 15 Wrangler and wonder if I should check and or change that oil?

It's possible. Anything is possible. It doesn't take very long to check the fluid to make sure there's enough. Pull the fill and stick your finger in.

The dealer is supposed to check that plus everything else when it's prepped prior to delivery, but you can easily check it. I wouldn't change it on a new vehicle. After some miles you might want to consider switching to synthetic.

Definitely worth checking. I have a '14 and changed out manual transmission fluid to synthetic in October (1 year old) to reduce the stiffness when cold. Drained just over 1 qt and I filled it with just over 2 qts before is started flowing out the fill hole.

I just checked my '15 JKU and when I couldn't feel any fluid with my finger decided to drain/replace. I drained out just under 1.5 qts, while putting in nearly 2 before it started oozing.

I didn't notice bad shifting necessarily, but it does seem a bit smoother now. Definitely check it, lots of good advice on this site to assist

Certainly worth a check, and easy to do. Mind was quite low. The dealership failed to check it upon delivery no doubt.

Drive it for a few hundred miles to break in, then drain it to get the crap out and refill with Redline MTL or Pennzoil Syncromesh.

Its not a difficult job with a fluid pump. You'll know its full and get the slightly smoother shifting benefit of running the synthetic.

I have a 2012 and changed the trans fluid this past spring. I used Amsoil Synthetic Synchromesh Transmission Fluid. Based on what I drained out of it, I was about a qt low.
Also changed the transfer case fluid at the same time and it was a touch low too. Just used the Mopar ATF +4 fluid in that one.
