My son bought a 2019 FiST

[ArabianOak]

Hello Everyone,

My son just bought a 2019 FiST with 2000 miles. I've driven it a few times and I noticed that first gear is much more vibey than the other gears...it seems like the shifter moves and vibes a lot more in first gear than others. It doesn't do it all the time, it doesn't pop out of gear and it shifts great.

I called the dealer this morning but they cant get the car in for a week! Before scheduling the appt I wanted to inquire if this was normal?

We also plan to cobb tune the car later in the week and if it is not normal than we will wait to tune it before having the dealer inspect.

Please let me know. Car is awesome!

Could be that your experiencing the effects of the stock rear motor mount. The stock one is a known weak point and would explain your systems. After market rear mounts are a must for this car

Thanks. That was part of the Cobb stage 1 kit we ordered. Is that a tough install?

Nice! Diving right into the rabbit hole! 1st mod=Rear motor mount. Go with a Whoosh from Ron or an AWR. This will reduce the shifter movement for sure.

Pretty easy install in my opinion

easy install. low profile ramps or jack stands. 7 nuts/bolts to remove. do NOT over-torque.

Awesome. I’m doing the blow off valve too. So I’ll jack the car and dive right in. Lol. Any install video on the motor mount?

1/2 hour to install a rmm typically. I'd say bite the bullet and upgrade all 3 to something aftermarket. The oem engine & trans mounts are notorious for being weak. Inserts on stock mounts help, but by design, they put more stress on the oil filled rubber bushings and shorten their longevity. Might take a couple hours to change out all three and the results are amazing! Crisp shifts, less torque steer and wheel hop. Personally, I love the added NVH. It makes driving a more visceral experience

Just FYI for op, I have PowerFlex inserts and it improved shifting and wheel hop immensely. Mounts all the way around are awesome but pricey. Just a more affordable option if you’re not tracking the car

Agreed

Thanks. I just wanna make sure it’s not synchros or some other trans issue.

Do you guys revert to stock tune for warranty work? Can the dealer see the Cobb tune?

Always revert back to stock tune for warranty work, if a dealership has reason to believe you have flashed a tune they can tell if they look hard enough

Prob a good idea to revert back to Stage 0. Only takes a minute or 2

 

[ArabianOak]

Thanks!!! Cobb stage 1 will be here tomorrow.

Go as far as to uninstall the ap, the ap locks out obd scanners if they should hook one up. Dealerships can freeze frame data from before you brought it in. Again they typically do this only if they have reason to believe you tuned it. It’s federal law also that to void a factory warranty the part in question had to directly cause the failure. I.E a motor mount won’t cause the turbo to fail.

My Daughters 2019 and my 2016 have never shown this problem, perhaps you have a defective OEM RMM. 36K on mine and never any transmission issues of clunking or vibrations. When I bought mine I thought from reading the comments on the Forum a RMM change would be needed, but have never had an issue. My daughter's is at 7K and has no issues. I suspect many of the cars with this issue on the Forum are used harder than most and more modified than my MP215, also mine nor my daughters cars have ever had a drop the clutch start from a standstill and never will, we do our hard driving on curvy mountain roads. If your Son is more into street/track racing a stiffer one may be in order. Either way, I would suggest you get Ford to resolve your issues before modding the car. May prevent possible warranty issues later. Good luck!

I’ll post a video of it shortly. Hope that helps!!
