odd noise from the transmission?

Good morning all,

I have an interesting situation with my 2012 Jeep Wrang. Sport, automatic.

I have been noticing recently that when I am going about 5 mph or so and coming to a stop there is a faint, 1 second noise which best described sounds like a "errri." It does not occur every time but it is best heard when my windows are rolled down.

It seems as if it happens when it downshifts into first gear from second gear.

I am not sure what is causing it. I did take the jeep in for the transmission oil cooler recall and I am wondering if that had anything to do with it since I don't recall it making the noise prior. I am still under warranty. I just don't want them to tell me when I get there that it is just old transmission fluid and needs to get replaced.

I have 33,000 miles.

Any input would be appreciated. Have a great day.

Joshua

Did you check your transmission fluid level, after they performed the campaign?
They should have checked it, but did they........

I can't recall. I think I did because I went on a long 2,000 mile trip just after they did that work and I usually check my fluids before trips like that. Would low transmission fluid do that?

Yes, low fluid, can cause some strange sounds.
I would also check out the routing of the lines that they installed, to make sure that they are not vibrating, from a engine harmonic.

Thanks Old Dogger,

I really appreciate your feedback. I'll be checking those two things. Have a great rest of your Friday. God Bless.

Hmmm, have you looked into it at all? I am just curious if you checked the oil level and it was corrected. Thanks.

When the transmission shifts to different gears, a solenoid(s) opens or closes diverting transmission fluid to different circuits within the valve body. The first step as mentioned is to check the fluid level. The noise itself is due to a normal function of the 2-1 solenoid but may be more audible if there is a lack of transmission fluid. Stand on a street corner for a minute and you'll hear that sound a lot.

Ok, so I checked the fluid a couple weeks ago and that is good and normal. I still hear the noise though not every day. Could it make a difference if it is cold or warm (weather or engine)?

Temperature can have an impact. However if the level is full bring it back to the dealer and let them check. Just make sure the fluid is not overfilled that can cause problems too.

Ok, thanks for the responses. I will double check the level and make sure it is not over filled. I'm pretty sure it is not. I dislike going to the dealership. Argh. But at least I am still in warranty.

Good question, got a 2012 Wrangler JKU, Auto, there is no "dip stick" to check the transmission fluid....I'm depending on the dealer to check this when I get my 3,000 oil changes done. I'm not used to this,( used to the good old dipstick ) I was told they check it by temperature?? How can MYJEEPFUN and everyone check like you should be checking every week or so, check the trans. fluid like the oil and all other fluids with the auto?

Hi Ed,

If you lift the engine cover it exposes the transmission fluid dipstick. I'm pretty sure that it is in the owners manual too. It is yellow and on the left hand side of the engine.

Joshua, just my opinion...did you check your rear brakes? I was getting an noise coming to a stop at about 5 mph, looked at the rear drivers side inside pad and it was thin.
You will be lucky to get 35,000 mi on your rear brakes, the nannies come on often and wear them out.

It really does not sound like brakes and when I hear the sound I don't have the breaks depressed. Were you getting the sound only when you were pressing the brake pedal? Thanks for your response 285HP.

Ok so I have kept an eye out for the sound. A little update:

I noticed it more today when I went on a 40 mile trip. I only notice it at stop lights. It is when I start up and when I come to a stop.

Also, I hear it when I turn off the jeep, even when it is not moving. I think this is more of an indicator of what it could, but I still don't really have a clue. Best guess is transmission, transfer case, drive-shaft, nothing else seems to come to mind.

Rick92f, could this still be a symptom of a bad solenoid? Thanks! Have a great day.

Good morning,

Happy Friday, I wanted to give an update. I took my jeep to the dealership to diagnose the issue. They said that the noise is normal. They pulled one of their jeeps from stock and confirmed it. I guess this makes sense with Rick92f's post about it being a solenoid or something like that. I am a little protective of my jeep I guess, better safe then sorry!

Peace
