shifting into 2nd gear is grindy

I own a 2000 2.5L 4 cyl manual wrangler. recently i have been having problems shifting into second gear. It kind of grinds or "clicks" into place unless i really baby it/shift slowly. I have read on here that maybe all i need to do is switch the transmission fluid, or should i take it in to have it checked out? maybe i have cluth problems, i really dont know. any recommendations?

Joe.

It's hard to know without actually hearing it. It could be normal shifting noise or it could be a worn out synchro. I have the 4.0L I6 with the 5 speed and it grinds a tad when shifting 1-2, especially when cold. I've been told this is normal because we have "truck" transmissions, meaning a very steep 1st gear. I wouldn't be too worried about it unless it becomes apparently worse. Changing fluid may help a bit, especially if you haven't changed it in a long time or ever. But don't expect miracles, it's just lubrication for the synchros.

thanks for the reply. i talked to a friend mechanic. he also said that it sounded like a worn out synchro but it should be fine as long as i dont drive crazy on it.

Rather than speculate and coping with it. I would suggest changing the transmission fluid that will eliminate fluid quality, something that is often "forgotten" maintenance. I'd also suggest flushing the clutch fluid via pressurized bleeder, and keeping clean fluid in the reservoir. If its still clicking or the teeth are catching with proper shifting technique. Its more likely to think its the clutch dragging usually being pressure plate or throwout related, when the CMC, lines and slave are in working order.

They all grind in second if you dont shift it right. Do a serach about it and you'll see about 100 other threads about it. My 2000 2.5 manual did it too.

Try taking off the shift boot first. In colder weather the rubber boot can make it hard to get into 2nd gear. I replaced my boot with a cheap $10 one, and now it shifts really smooth.

That's a common problem with the synchros wearing in the older model Jeeps.Change the gear lube to a better brand and it will help somewhat.My 98' did that and Redline MT-90 helped.It never got worse over the next 2 years before I sold it.

alright so i've decided that im going to switch out the tranny fluid. I was doing a lil research and I found that u should use 10w30 full synth motor oil (because i live in minnesota with brutal winters) and apparently the 10w30 is the new spec for the AX15. anyone have any commentary on experience using the 10w30

You have an AX-5 tranny.

3.3 quarts 75W-90 GL3, 75W-90 GL4, or 10W30 (NOT GL5 or GL5 compatible as incorrectly stated in some of the manuals)

I should use a full synthetic since I live in a colder climater , correct?

Do what boogyman says, use the Redline. I live in MPLS and I used it on my AX-5 and it worked wonders for me. I had a hard time finding it locally. I got some from Courtny truck service in Eden Praire.
