The dealership says the noise is coming from the transmission because the fluid is too low. They say the driver's side axle seal (the new one that I replaced) is leaking. It sounds like a bunch of bullshit to me. I've heard what a low fluid trans sounds like and it's not this sound. Why would the noise only be heard out the passenger window if it was coming from the transmission, which is on the left side of the car? Why is my brand new Mopar seal (that went in without any issues) leaking already? The whole thing is fishy. I told them to top off the trans fluid and let me come get the car. I'm going to pick it up tomorrow and check it out for myself. I'm willing to bet a million bucks that, even with a full transmission, the noise will still be present because it has nothing to do with the transmission. Apparently I need to pull the axle and replace the seal again. Maybe I'll throw in the stock axle to see if the new one isn't sealing properly.

Weird pretty easy to check tranny fluid level. Just pull off rubber plug and the fluid should be right near the top of the fill plug. I need to check mine for the heck of it. Wish you had a video of said noise. You should make sure your tire isn't rubbing on something either.

So they are saying the axle seal your replaced is leaking. That sucks. They got to go in very carefully I know that and if damaged when going in can ruin them.

Here are some threads that might help, just random info and opinions:

Good to know you can bend that piece and it won't leak:

Says to use a bead of black RTV around the seal. I never did but it might help.

This is the how-to I used a long time ago when I did mine on the silver SRT-4

Thanks, man. I've read every one of those links already. I researched the hell out of this. I installed the seal exactly how they said to and it went in perfectly on the first try. I don't know what's going on. Maybe those cheap axles aren't sealing properly. Who knows at this point.

The noise sounds like the front brake is dragging just a little bit. It's really faint and high pitched at this point. It oscillates proportionately with vehicle speed. Definitely not the whine of an empty transmission. The fluid was really low on this trans when I bought the car because the end plate leaked like crazy. I know what that sounds like and this is not it. This car is fucking cursed.

The bearings can also rattle in the trans with low fluid. But yeah, I have never heard anything like you describe from low fluid in an MTX.

The oscillating sound might be from a CV joint. Or possibly from tires. Swapping wheels around might eliminate it, if it is tires creating a weird harmonic sound.

The winter tires on my Impreza were making some odd oscillating sounds. The noise went away when I put the summer tires back on. After replacing a halfshaft, and then a wheel bearing this winter, I was getting nervous, as it is fast approaching 200,000 miles on the original parts, and this car was badly abused before I bought it, which can't help matters. Thankfully the tires solved that sound. The winter tires are going to be marginal for another season anyways.

I don't know about you, but I don't think that looks like a leaking seal. The trans is obviously weeping from the seams, but not enough to drip anywhere. The moisture below the seal looks like remnants of the fluid that poured out when I removed the axle about a hundred miles ago. The axle itself is dry. I think the dealership was full of shit. The noise is still there.

P0340 and the car won't go over 2200 RPM. Looks like it's time for a new CPS and probably the magnet while I'm in there. Never a dull moment. Good thing I have a backup vehicle.

There's a lot of research out there for this code. I'm going to play it safe and replace both the cam sensor and the magnet. I'm also going to clean up all of the engine grounds around the sensor and reset the computer. I hope that all of these known fixes done together will be enough to do away with this issue on the first try.

My CPS went out years ago the day after driving back from a meet at chipdogg's in WI. Good thing- I would have been stuck on an interstate somewhere in IL otherwise. CPS was replaced under warranty but I also had the magnet taken care of as well after others here suggested it. I'm still appreciative of the advice given me on that one.

Unless the engine shut off, the cam sensor won't leave you stranded. The PCM just fires the injectors in batch mode vs sequential. For future reference, if it did kill the engine, you should be able to unplug the connector, and run in batch mode. It is very simple to get to on DOHC engines, so knowing that could save you an expensive tow bill. The only year that will not run with the cam sensor unplugged is 1996.

My guess is they limit it to ~2000 rpm, so you will fix it, and just not ignore the CEL, as we know 70% of the masses will. The only advantage to sequential is better idle and low rpm quality. Once the engine is spinning above ~1500 rpm, there isn't enough time for the fuel vapor to sit around in the ports to really matter. Basically they are holding your performance as ransom, so you'll service it.

Kind of like Subaru disabling traction control, hill climb assist, and a few other things on an MTX, because the reverse light switch fails. If it can't sense the gear, it won't do squat. It will otherwise drive fine, but you'll have no "perks".

Yeah your seal looks fine to me. As for your Cam Position Sensor. Do it right the first time. Mopar magnet and sensor. Buddy did the autozone adventure with the sensor and it kept going bad. As others I have read.

Mine went bad on a previous SRT-4, I could still drive it but couldn't go over a certain RPM. Sucks because I was on the interstate too. Forget what speed I had to max at. I think it was like 50 something in 5th gear.

I say if you took your car to a shop and they were supposed to find the noise and you spent your hard earned money to have them diagnosis it. I say take it back to them! Unless you don't want nothing to do with them and move on. Any leads on what it could be?

Mopar sensor and magnet have been ordered from Modern Performance.

I'm done with the dealership drama. They don't know what they're doing and I don't trust my car with them anymore. They gave me a huge clue when they tightened up the brakes and made the noise quieter. I'm going to replace all four rotors and pads soon, so we'll see if that makes a difference.

Magnet and sensor installed. I cleared the code with my OBD2 reader and all seems well again. You know, other than the random noises and leaks.
