Hey everyone,

I bought a brand new manual Scat Pack yesterday. Aside from this issue, happy to be in the Mopar club! I was driving it on local, low speed roads last night to break in the engine and noticed a troubling issue. Over the course of a hour or so, second gear grinded 3-4 times. Now, I’m an experienced stick driver and I don’t consider the clutch on this car difficult but still at first I just assumed it was driver error being that the car is brand new. But after the first couple times I anticipated it happening and made sure the clutch was firmly against the floor and that I shifted affirmatively - the issue repeated! It seems to be lower speeds, possibly traveling at a slight decline and coming OUT of second gear, even with the clutch 100% engaged. The weather was warm (75+) and humid. I’m upset to already have an issue in a brand new car that I know the dealer will ignore, that is possibly damaging the transmission and making me look/sound like a fool driving through town lol. Anyway, silver lining is that it got me to sign up for this forum early. Please please send any thoughts or suggestions and thank you in advance.

Since it sounds easily reproducable and It's a new car, take it back to the dealer, get the service manager in the car and show them.

If you don't like that service shop take it to another dodge shop and show them.

Also there is a @DodgeCares member on here you can contact and they will help you if you are having issues.

At low speeds just cruising don't even need 2nd, just go 1-3-5.

I know doesn't help the situation but at what speed was your shift to 2nd attempted?

@Slidd, I would wager a guess between 5-15 mph but I could be wrong about the range. I’m taking it out again today and will pay closer attention.

Thank you to you and @Slwkat I will most likely take it to the dealer soon.

Its common on cold drive off to get 1st > 2nd gear nibble - but shifting out of 2nd and grinding isn't something I've heard about.

I've driven 15s / 16s / 19s with M6 that had miles and some pretty much brand new - that behavior you describe isn't normal.

they can be a bit balky until you get some miles on them and they break in - but that's where things get smoother and shift efforts are easier as well

Agree with the advice of others: New car. Has warranty. Take the car in and demonstrate the behavior. If (when) you hear "they all do that" ask this be demonstrated with another new car off the lot.

Briefly, back in June 2009 I bought a low miles used car with among other things a 6-speed manual. The shifting was less than smooth. Not operator error just the transmission. Since another car I owned, same brand, shifted buttery smooth but had a smaller less powerful engine -- and a different transmission: 5-speed -- I attributed the shifting issues to the transmission being heavier duty and therefore less likely to shift smooth.

At some point I had the car in for an early transmission fluid service. Tech spotted a selector shaft leak. Long story short factory decided to rather than have the tech "rebuild" the transmission to instead replace it with a new one. A new one was shipped from the factory (in Germany) and installed. All under warranty, thank goodness.

New transmission shifted buttery smooth. The difference was amazing.

My point is any car can come with a bad X. In this case the 'X' is likely a transmission. Get it taken care of sooner rather than later and then you can really begin to enjoy your new car.

@Hal H Thank you for your response. I made sure to research this issue a bit before posting and saw that about the nibbling. It does feel like a “nibble” - but as you said, unusual in that it’s happening coming out of 2nd. Someone had previously suggested rowing the gears in reverse order to lubricator them which I will try as well.

@Rockster Thank you for your thoughtful response - you’ve given me a lot to go on. I will definitely take it in as soon as I get a chance and will ask that they check the selector shaft for a leak as they examine it. Looking forward to opening her up without apprehension!

Wanted to add that one "test" you can do before you take the car in is with the engine at its normal hot engine idle speed and the car on flat ground from neutral and with the clutch pedal pushed all the way down you should be able to move the transmission gear lever from neutral to any gear -- other than maybe reverse -- with no grinding or any other untoward behavior.
