Smoother shifting?

How can I achieve this? I'm referring to the transmission itself sounding kinda rough when I switch to certain gears. Is there some kind of oil or something that helps with this or what?? Maybe a newbie question so I apologize in advance.

It may be that the synchros are worn or the shift gate where the shifter is steered through is worn, but often a gear lube change can help. Is the gear lube in there old and broken down maybe?
I've never had a smoother shift than with Sta-Lube from Napa auto parts. Possibly worth a try. (Hints if you do: Remove the fill plug first to make sure you can get it out to refill before you pull the drain plug. But the cheap lube pump they sell to make refill easier.)

Do you mean like sounding like its struggling to put power to the wheels like a rough sound coming after you shift and let go of the clutch, just like if you we're to shift too early?

Sorry guys just now got a chance to get back on. I'll have to look into the stuff from napa. Thanks man. And for the other questions I have a 1997 4cyl 5 speed. And no not necessarily it struggling to get power to the wheels, but just the actual sound of me pushing the shifter up into gear, and the feel of it. It just sounds and feels like its real dry in there. Especially when shifting into first.

Some guys swear by Redline synthetic gear lube to smooth up shifting, but I have used both in a old tranny, and the Sta-Lube worked better for me, so I put the Sta-Lube back in. Make sure you get the right weight and GL number. (Some is GL-4, some is GL-5, etc...) I don't know what the Jeep calls for, but it should be in the owner's manual or online somewhere.

I think you have an AX-5. Certainly go for the fluid change if the jeep is new to you or been in water but the last easy shifting Jeep I ever had was a Willy's with a T-18 and a TJ with an automatic. Seriously, they will never shift great like a car. Nature of the beast. You may have already noticed that if you don't try to force the shift which will get ahead of the syncros, they shift a little easier. They like a relaxed shift. Redline MT-90 GL4 will work good in an Ax-5 but it is expensive. If you don't plan on going in the water a lot, it's worth the money. Hope that helps.

Sorry, don't mean to hijack the thread but, im having the same problem with my 99 4.0l 5 speed. Shifting in 1st and 2nd is pretty rough, and sometimes doesn't fully engage in 2nd. Should changing the fluid also work?
