Also, the neutral idle rattle doesn't stop like it used to when the clutch pedal is depressed. This is a sign that the problem is worsening. The 3rd and 4th gear rattle was solved with installation of a non-MOPAR shift knob.
i pushed the shifter towards any gear just far enough to feel that it was in its "gate" of that particular gear....make sense?
my growling is happening more frequently and a bit louder. i am also having the same issue with the throwout bearing noise not quieting down when i push in the clutch.
how many miles are on your trans? has the dealer done any repairs?

I'm going to try what FAMILYTANK just posted re: his shifter to see if I have the same result.
cyrojeep, did you try the shifter test like i did with my jeep? results?

how many miles do you currently have on your rebuilt/replaced trans. if it has been replaced, has any work been done on the new trans?

Or maybe its just normal, and like I've been thinking, I'll just deal with the sound. I had the dealer check the level of oil in the tranny, and everything was fine, so maybe its just a noisy beast. If there is no harm happening to the transmission, then I don't think I really care. What did your mechanics say about damage, if any?

Have you checked your oil level, too?
I get it back tomorrow from the dealer. They called today and said the shift rail was replaced and after they do some testing that I can have it back. He said they did not see anything wrong but also did not know what to look for, not even sure it is at transmission problem. I never did check the oil level but it should be good after being put back together.

Aftermarket throw out bearings are documented as being better quality than MOPAR. However, Chrysler will not authorize installation of non-MOPAR parts.

I talked to my parts guy where I bought the fluid pump for the trans oil, and he told me he worked for Chrysler for 30 years. On his own initiative, he says he checked with former Chrysler colleagues about the rattle issue, and they told him they know all about it but don't have a fix. This seems to bolster the reasoning behind why Chrysler won't document to me in writing that the noise is normal.

The 'other' grinding noise you have sounds like a bad bearing. It could be a wheel bearing, a dragging brake rotor, or a differential. Do you know where it is coming from?

Try taking it through a car wash to see if the noise abates afterwards (water is a great lubricant, and it may help in isolating the cause). That the noise occurs when the vehicle is warmed up points to a bearing to me because lubricating oil will thin as the bearing overheats. Possibly, something was not aligned at the factory, causing bearing damage? I suggest having your dealer check the differential fluid levels to rule this out.
...as for the fluid change to red line, i have a feeling that it may noy help. i agree with you about it being a bearing. possibly being a input bearing. whether slowly rolling forward or reverse with clutch pedal pressed and in gear, it growls like bad bearings. i already changed front and rear diff fluids...what leads me to believe its more trans or clutch is, when i coast with clutch pedal out and out of gear and just coast - no growling. also, if i let it idle, clutch pedal out and out of gear, if i slowly move the shifter toward a gear, it will stop that idle noise. once i move the shifter back to center, it returns. on that particular noise, does that sound like thrust washers out of spec ? my dad and i have rebuilt old muncies and borg warners trans a decade a go, so this situation stumps me.
thanks again

i can get the noise to stop (possible throw out bearing) when i push in the clutch. for the OTHER noise...the growling will stop when the jeep stops. it is at its loudest at near stop (under 5 mph). the scary part is, when the tech and i drove the brand new jeep off the lot, we warmed it up and the noises like mine appeared (though faint). what i do not like is that there seems to be no solution/fix for some of these issues. i do not want to go back several times for the same issue with no fix. if that is the case, i will just start the lemon law process. i cannot believe after 8 years they cannot fix this trans. our family has owned jeeps for 40+ years and this latest jeep has been a downer. my dealership is great, but jeep themselves have been horrible with this issue.

danrb My rattle has pretty much gone away in cold weather. I occasionally get some, but it is less. Took a long road trip and had no rattle. I think it is related to temp and traffic.

FAMILYTANK [QUOTE=campbell2209;16226497]Monday they said they would change the fluid and call me in the morning to see if it fixed it per Chrysler. I think they opened a STAR case...

Well the dealer called Tuesday and said no luck and they want to remove the transmission again and tear it down and inspect it. I told them I have had enough at this point and filled out the form in the blue & white book and filed for lemon law.

I feel like they are just tearing my Jeep apart and throwing parts at it again and again. I turned every bolt on every mod and handled it with care. It really pisses me off the techs seem clueless. I would be willing to get another one if they offer it to me but ONLY and automatic.

I will let everyone know the progress.[/QUOTE

do keep us posted...i must say, you have been more patient than i. 4 + rounds of repairs and no solution/fix. this is one reason why i am on the fence about having the dealer start on mine. i promise you this, i WILL execute the lemon law if this happens as it had with you. i did it 10 years ago. it was tough, heartbreaking actually, but it worked out for the better. it needs to be known to these manufacturers that they cannot continue to disregard a inferior/incompetent product.

Boss 302 Going to have to try this shift knob test...thanks for the tip

Cyrojeep I have dealt with several dealers now and have come to the conclusion that they really don't understand this issue.

In general, there seems to be two rattle sounds with the manual transmissions: a neutral-idle one, and the 3rd and 4th gear rattle. Below are possible causes I have compiled:

  1. Internally damaged transmission: loose countershaft assembly, bad synchros.
  2. Incorrectly installed transmission mount. One dealer told me that this is the source in some cases.
  3. TOB. This seems to be a prevalent culprit of the neutral-idle rattle. There are several excellent videos on YouTube about this, and a non-MOPAR part is a popular fix (Federal Mogul or National brand part).
  4. Transfer case cable. Forum members have posted how the hard plastic cable jacket running to the transfer case rubs against the chassis causing a rattle. Repositioning and/or lining the cable with a rubber coating/jacket seems to work in these cases.
  5. The factory shift knob. The shift pattern etching on the top of the knob rattles. This is the cause of the 3rd-4th gear rattle in my case, as I found myself thanks to other Forum member posts. A replacement knob or a non-MOPAR knob is the fix (i.e., Drake or some of the custom knobs made by fellow Jeepers).

    To see if this is applicable, do the following while accelerating in 3rd-gear (in order to make the rattle prominent):

    1. Place your fore-finger and middle finger around the base of the transmission shift knob.
    2. Press down VERY HARD on the top of the shift knob with your thumb, moving your thumb around the top of the knob to see if the noise changes.

    If the noise goes away, the transmission shift knob is causing the rattle.
Changing the transmission fluid to quality synthetic oil seems to help reduce rattles. Both REDLINE MTL and AMSOIL MTF state they meet Chrysler specifications. REDLINE is slightly thicker than AMSOIL and is a 'clinging' type of oil, which seems to be preferred by "Old School" Jeepers based on posts.



Finally, if the Dealer says the noise is normal, get them to document it. If they don't, that's a huge red flag. Most states have auto repair acts, which requires by statute documentation of issues. For my part, FCA (formerly Chrysler) will NOT document that the transmission rattles in my Jeep are normal.

I highly doubt all of these transmissions spanning several years of production have bad bearings or some other problem new from the factory. If so, I imagine there would be a thread with 100 pages stickied to the top of the forum with complaints of failed transmissions. There is a lot of complaining about the noise but I just don't see complaining about manual transmissions blowing up. Realistically, I think letting the dealer open up the trans is more risky than living with the noise.

Back in 2000, I bought a brand new Ford Focus that had a rattle idling with the the clutch out. If you pushed in the clutch, the rattle stopped. Dealer replaced the clutch at 20k miles to fix. The noise came back within 1k miles. Well, I sold the car at 120k with that same clutch still working just fine. Long story short, it was just a quirk of the car. I think the same thing is in play here with the Jeep. NVH is just not something they gave a shit about when making these trucks. Ok, rant over.
I couldn't agree with you more.
