| My son drives a 95 wrangler 4 cylinder 5 speed. When leaving work the other night he said he had trouble getting it to shift out of second gear. When it did come out, he said it "popped" out and now it is stuck in neutral and will not go into any gear. Any idea what the problem might be? Now he is driving his mothers car to work and she's not happy! | |

Replying to: mac24 (Feb 15, 2009 7:16 am) Tried what you suggested. It will go into any gear with the engine OFF. If it is just the gears meshing, it's just disconcerting that a vehicle with 27,000 miles (now) would seem to be such poor quality and makes all this vibration noise. Gee, having grown up in the muscle car era and having owned 3 GTOs, a 455 T/A, and a '64 Corvette, none of these cars ever had this problem. Thanks again for your help. nomad443

Looking at your original post #115, it sounds like the classic symptom of a bad transmission bearing, probably the one on the input shaft. When the clutch pedal is depressed the input shaft is disconnected from the engine and stops turning. However, whether it's the bearing or the gear itself, the transmission has to come out to examine and replace it. Two points, if 'they all do that' challenge the service manager to demonstrate it to you on a new Wrangler; and I'd question how gentle the first 24K miles were if one of the axles required a new r&p.

Replying to: mac24 (Feb 15, 2009 1:58 pm) Thanks for your input. I'm going to visit our 2 reputable 4-wheel shops in my area and run your diagnosis past them before I visit the Jeep dealer service manager who gave me the gear-meshing bull. You sound pretty much like you know what you're talking about, so what is your experience with Jeeps, if you don't mind telling me? I'll probably refer to you in my discussions. Don't really need your name. Probably mentioning Edmunds will suffice. Thanks again for your help. Sounds like I might need to put out some serious bucks. nomad443

I had another guy that works on transmissions tell me that it sounds like the synchronizers went out on it. The synchronizer rings, or synchros as they are often called, grab the spinning gears and allow then to match speeds so that they can mesh smoothly as you change from one gear to another. The syncros have no effect when the gears are stationary, so whether they're good or bad it'll make no difference to gear selection with the engine off. It's also highly unlikely that the syncros would fail on all the gears at the same time. Your transmission should be an AX5. If you can get another one that's in good condition, great. If you get one that's worn though, you're back to square one. |

Replying to: nomad443 (Feb 15, 2009 7:46 pm) Once you've established whether the noise is excessive or not you can go on to fixing it. There is an outside chance that it's the release bearing, which will require transmission removal to replace it, but not the stripping of the transmission itself. However, the normal problem with the release bearing is the other way around, noisy under load and quiet when released. It does happen backwards sometimes though. However, the most logical diagnosis is that it's an internal transmission issue, either a gear, shaft, or bearing (or possibly even a lack of lubrication). While idling in neutral a limited number of parts are rotating, with the clutch pedal depressed none of them are rotating, so the noise stops. This isn't specifically a Wrangler problem though, it can happen with any manual transmission on any make or model. The fact that you have this issue, coupled with the need for a replacement ring and pinion in one of the axles, suggests that your Jeep may have previously led a hard life. My C.V. is immaterial really, I never claim to have the definitive answer to anything, and any advice you get here is only worth what you paid for it. However, if what I've said makes logical sense to you, then it gives you an understanding of the problem that you can comfortably discuss.
