Shifts, and then wont shift.. and shifts again by porterz

My brother in law is having trouble with his jeep.. Im stumped. The jeep seems to shift decently till you hit 4th. Upon hitting the clutch and shifting out of 4th though.. its stuck.. wont shift to any gears.. moving or stopped. It also wont shift into a gear until the clutch is pumped. This seems to reset the tranny and then you can shift into any gear. If the jeep is turned off while the jeep wont shift.. well then you have to turn it back on and pump the clutch to get it free. Just curious if anyone has any ideas before I tear it down.

2006Rubicon transmission noise by rube5

At 29000+miles, my Rubicon 6-speed neutral gear began vibrating with an annoying sound. This sound is quieted by depressing the clutch and/or slightly moving the shifter. The transmission was replaced but the sound continues. I now have 31000+miles on the odometer. I have visited three different dealers: #1replaced the transmission#2replaced Transfer case shift rail torque bracket#3Originally, recommended the replacement of the throw-out bearing and pilot bearing. I did this and it cost me almost $500. I returned and I was told that the noise is normal due to gear lash between input shaft and counter shaft. No problem found. I would appreciate any insight from other owners. Thanks in advance.

Jeep wont shift by porterz

Ok have now replaced the clutch and throwout bearing.. still have the shift issue. It only happens on the down shift.. and only in the 3 4 slot. At this point Im leaning towards the 3 4 shift fork. It tries to engage the gear, and then hangs up and wont shift to any gear then. if you skip 3 and 4 and go from 5 to 2 there is never a problem. Anyone else had a problem or heard of a problem similar? With the clutch depressed there is a noticeable rattle when it wont engage. Stopped when you release the clutch it also causes the jeep to lurch slightly and then disengages the gear. If you park with the clutch in and unable to shift upon turning off the jeep you cant drop the clutch for the reset.. it still wont shift. But with the jeep off it shifts perfectly every time. pls someone offer some help?

rube5,
 
I completely sympathize with you. It drives me nuts! I took my 2004 Sahara (28000 miles) to 2 local 4-wheel shops. One said he thought it was a needle bearing and would only increase in noise level but would not be a major problem. Had the tranny (NV3500) replaced at the 2nd shop, plus the throwout bearing. Seemed tight for about, oh, 2 weeks. Shifts fine, but noisy at shutoff. I think it's a Jeep tranny thing. One replaced is guaranteed for a year, so we'll see what happens.
 
Please excuse the fact that I'm not a motor-head by any stretch of the imagination. Just have a Wrangler for summer rides and extra 4-wheeler for winters here in PA. Hope somebody has better info for you.

2006 Wrangler Automatic Transmission Problem? by 06jeepunltd
Jun 04, 2009 (6:44 am)

Bought a brand new 2006 Wrangler Unlimited (my 3rd new Jeep Wrangler) and have had a problem with the transmission when the weather begins to get cold. Symptoms are, when temp goes to around 50 degrees (and car is still cold from start-up) there is a problem when I stop and begin to accelerate. The downshift to first gear is not immediate (2-3 second lag) at which time you can feel the trans re-engage and all is well until the next stop, although when very cold there is sometimes an abrupt hard upshift from from first to second. In late spring, summer, and early fall all is well which makes me believe temperature is the contributing factor here and not a mechanical one, as the transmission is smooth shifting and normal at all other times. When I returned my customer rating sheet to Chrysler noting the problem, I was contacted by their engineering staff and they seemed to know about this. They were familiar with these symptoms which lead me to believe I was not alone with this.
 My question is; is/was this a problem that led to a service bulletin fix such as software corrections. My Jeep has only 11,000 miles and is still under warranty and there is no sign of problems with the fluid. I am reluctant to have transmission pulled because of this intermitant problem which I can live with. Thanks

1998 Wrangler Sport Auto Tranny Issue (?) by thegrlfrmtahoe

So, maybe a couple weeks ago, I noticed a sound. The only way I can describe the sound is either like when mud dries and flies off your undercarriage while you're driving or maybe like a rusty bolt rolling around in the back. I wrote it off as something like that, until I cleaned everything out, checked underneath and didn't find anything loose, and the sound hasn't stopped...
 
Fast forward to a couple days ago, I notice that I'm super sluggish when accelerating from a stop, like there is absolutely no torque. Once it catches second its fine, and it's fine at cruising speeds.
 
I don't know if the sound is connected to the issue or not; Lord knows with the luck I've had lately, the whole bottom is probably about ready to fall out of it. I'm just hoping I don't need a new transmission. Any ideas?

Sorry, I'm just a driver and not a mechanic by any stretch of the imagination. Had a '98 Sahara before trading up to a '04 Sahara and never experienced anything you've described. My only suggestion would be to take it to a REPUTABLE 4wheel shop and get their take on the problem. Good luck!

When was the last transmission fluid change?
 
Perhaps a fluid change with some good fluid would help.

auto 5 speed by randy0730

Hello,
I have an 04 Wrangler. it is not very good on the highway as it continues to shift in and out of 4th gear. I have the 4.0 engine and the tires are not very big 31 x 10.5 x 15. the mileage on the jeep is 61K. Compression is good in all the cylinders. But going up average hills on the interstates (Alabama) it will shift down into 3rd at 60 mph. Is there an auto 5 speed that will rectify this or what is the next step/move?
 
thanks
