NVH When Shifting into 2, 3, and 4

[Phlyguy]

I must be the only person without grinding issues, and who is not freaking out about the NVH while shifting (synchros engaging). See the "thud while shifting" thread for my take on that issue. I've had a few times where it felt like the synchros were having trouble engaging as I shift from 1st to 2nd rolling down my neighborhood street, after being cold soaked all night in 17*F outside air. By the time I hit my main road, everything is smooth like butter. And I'm perfectly able to quick-shift this thing. Once the transmission is warmed up I can slam it into gears under hard acceleration just fine, or shift slow and it's still smooth. If it's frickin cold out, the fluid is going to be a little gooey until it's churned up. To me, that's absolutely a non-issue. If it were a 70*F day and I'd been driving for 30 minutes and it happened consistently, every shift, I'd be worried. This time of year, until everything's allowed to get to operating temp and stay there for a few minutes, things are going to sound rough.

Zero problems shifting here cold or warmed up:clap2:

I'll be getting my transmission filled with new fluid and the XL-18 additive once it arrives at my dealer. I talked to the service manager and it has been ordered so hopefully it will be here next week. I've also been hearing some diff noise so I asked them to order the XL-3 friction modifier and refill the fluid in the diff as well with the additive. Fingers crossed here, I will also be installing the Whiteline transmission insert along with all that. I will inform you guys of my progress once everything is done. If someone has already done it or will have it done before me please post about the results!

Well you are changing out the fluid in the trans and diff with the exact same fluid so I would not expect any difference from that.

In for feedback on the whiteline trans insert.

Here is the motocraft transmission fluid chart. Fluid is Dual Clutch Transmission Fluid XT-11-QDC with 27 mL of XL-18 Additive. So you're going to get the same thing as what is in the trans from the factory.

I'm curious. What are the ambient temperatures when you guys are experiencing this NVH? Anyone got videos of this?

Well, today going to work I was trying to make the left turn light before it changed and was in 3rd, but when I tried to get it into 2nd, it wouldn't go. I am not too worried. The car isn't broken in yet and also it was 45 degrees today. I don't drive it every day, in fact this is only my 3rd time out in it. I see there is a learning curve, so I'll get it. If it doesn't improve I might look into another shifter next year.

what do you mean it wouldn't go? did you forget to disengage the clutch? lol

Hi Guys,

After months of thinking, i ended up buying a Manual Transmission 2015 Mustang GT with Performance Pack, in Competition Orange with Black Stripes . Its been 4 days of awesome fun so far.

I have a question for you guys, may be a dumb question.

1) Does anyone feel a sound when shifting from 1st to 2nd gear ?

2)Or when you press the clutch down when shifting from 1st to 2nd,
or from 3rd to 2nd ?

3) Shift to 2nd gear doesnt seem smooth and it jerked the car few times as well. can it damage any parts ? It sounded bad but its running fine

Any Comments or suggestion to check it is appreciated, i was also thinking to take it to dealer to take look when i get time, but its kind of busy lately.

Thanks

Not sure how you feel a sound? :shrug: Your 1 & 2 are what everyone in this thread has been talking about. 3 just sounds like you need more practice with the clutch in the Mustang.

Not to be "that guy" but did you read any of the posts in this thread? I'm pretty sure everything you have mentioned has been brought up at least once. I see you are new, so welcome to the forums, but reading your friend :cheers:

Hi Rachel,

I have to apologize for going off topic here because mine has not been delivered yet and I would like to find out when my build date may possibly occur and I have a EDD. Should I PM you with the information? Again, sorry for going off topic. I just joined and learning the ropes. Gpz 550

The visceral sounds of magnificent machinery? That's all I hear. It's real cold here so I don't hear anything as mines bouncing off the rev limiter as I powershift 1-2-3 #TractionIssues

All in all, is this an issue in cooler ambient temperatures? I did not notice anything strange in the non PP GT I test drove. I only thought the clutch pedal was too soft for my taste but something easily fixed. I am in Florida, it's a very rare day when it goes under 60 degrees. 90% of the time is over 75 degrees with high humidity.
