I have an 07 rubicon with a 6spd ,How noisey are these trannys. Went on a 6 hour drive had a loud noise in 6th gear at about 60mph. I have 35 with 5.13 during the first 5 hours was cruzing at 70 but the last hour the trans was loud.Now this moring driving quiet again, ck the fluid all ok. Talked to the dealer today they said never heard of this. ??????anybody had this happen??

I have an 08' 6 speed- running 35's with the stock gears. The only abnormal or loud noises that I ever hear are sometimes during shifts (usually 1st to 2nd) and it is likely the throwout bearing or clutch, It really isn't too bad and definitely not loud. I also have a fairly loud exhaust but by the time the jeep is in 5th or 6th gear, it is barely noticeable.

How many miles is on your jeep?
What "kind" of noise is it?
Only hear it when engaged in 6th or is it between shifts?

Wonder if it's the transmission or (does it sound further back), like gears?

I have 8k on the jeep, I hear it in 5th and 6th,sounds like tin cans. Only we ingaged.

Maybe worn or damaged gear teeth or damaged synchronizer, input shaft bearing, or main drive gear bearing. Did you check the fluid for any signs of water (milky color)?

Surprised the dealer said they had never heard a noisy transmission...Is it still under warranty? If it is then I would get a 2nd opinion. A transmission is not cheap to pull apart.

Fluid is clean. I just hope they dont say well you have diffrent gears in it. It did it even with stock gearing.I guess I will bring it in see what they find.

my transmission is noisy, kinda comes and goes...i just turn the radio up now that i passed 36k miles...

 

[zonkerd]

On my trip my wife looked at me and asked are we going to make it? Thats how loud it was.I havent even wheeled it yet!I will bring it in tommorow see what they say.

Yea...Those extended warranties start to look good when you hit the 30k mile mark. I guess if the transmission held out till 35- 36000 miles, you are pretty fortunate. Last time I checked- Chrysler was quoting me something like 3 grand + just to pull it and take it apart. That was for my 06' TJ a couple years ago. I hope you guys (me included) will not have to have one dropped unless under warranty. Good luck to all.

 

[07_Rubi]

extended warranty aint worth crap if the mechanics are to dumb to diagnose the problem.

Moparpartsamerica.com has the manual transmission for 1800 bucks i think, plus there is ebay...

THAT is VERY true...Which is why a lot of us have avoided going to dealerships for even things like TSB and warranty work. There are many of us that have had our jeeps returned to us in worse shape than when the vehicle went in. And often times the problem is still as bad or worse. That's why I always stress that, if in doubt, or if someone feels that the dealership isn't honest or qualified (for any reason), that they at least try to find another dealership for a 2nd opinion, or one that may have a better reputation or is possibly more qualified.

 

[zonkerd]

Well dropped it off today.Took the tech for a drive did hear the noise.So they will call me later.

 

[StubEXrube]

I hate it when they say that.

I hope that all goes well at the dealership and they don't use the "Oh...aftermarket gears, huh?" to keep from trying to figure it out. Especially since you said that it had the problem before the gear swap anyway.

Good luck and keep us updated on the progress.

 

[zonkerd]

Just came back from the dealer, the tech wanted me to see the drain plug. Lots of metal chunks on magnet. His words were< only 9k on this thing this is way too much > He`s tearing it down right now. He took my cell number he going to call me tomorrow when he gets the tranny apart.

Is this the NSG 370 six-speed from Getrag..?

 

[zonkerd]

I think so Im not up on which 6 speed it is

 

[StubEXrube]

The 6 speed is the same NSG 370 as used in the previous TJ. It is manufactured in Germany.

Is this transmission "unique" for the JK or is this a stock transmission used for other customers (I understand that the case, bell housing and shifter cover might be different for other applications..) In fact what I like to know is whether this transmission is "unique" for the JK application (which has its own duty cycle..)

I only have 3K miles and so far all is reasonably OK. No way do I want to compare this transmission with the "Corvette" or "Mustang" manual transmission. (Ease of shift, smoothness, whine etc.. )

Indeed the first is a harsh shift, second has a "whine", the synchro's need time to synchro, hence slow shifting is required...(May be this is what Getrag had in mind from a $$$$$ point of view..:innocent

I will do some more research on this..(my old profession is coming back.. )

 

[zonkerd]
