Rough Shifting

Im new to the Wranglers. I just bought a stock 2000 2.5l with 103xxx miles on it about a month ago. It has been running great since i have had it. But i have noticed that shifting has become a little rough between 1st, 2nd and 3rd. When I first bought the car I didn't notice it at all, just started noticing resonantly. I don't know if it the cooler weather or if Im shifting too fast or the transmission fluid? I tried slowing down my shifting and that helped but it still rougher then i would like. My old 1993 Ford Ranger with 210xxx miles on it shifts smother then the Wrangler.

Cold weather definatly makes the shifting rougher. I would change the oil in the tranny to be sure there is good oil. Make sure to use the correct oil, I believe it is the GL5 not GL3 like most gear oils.

My '02 Sahara is a little notchy going in to second and third if I force it, but if I wait a second it falls in to place. I'm sure it could use a fluid change, and that's what I'd recommend for you to try first.

I shift my TJ's trans like a truck driver not like a sports car and it eases into each gear w/o grinding. If you force it past the syncros constantly the trans will fail sooner than later.

Colder weather makes the fluid thicker and the syncros rotate slower taking it a little longer to line up the gears. Changing the oil will help some but just be patient.

Definitly transmission fluid. I had the same problem for about 2 weeks, changed the tranny fluid a couple days ago and it's good as new
