Grinding from 1st to 2nd gear

[GT Pony]

I noticed same grind from 1st to 2nd @500 miles. Thought is was normal but started to notice in all gears especially if I hold on to shift knob. Took the car to the dealer for diagnosis. They first grabbed a brand new car from their showroom to compare and see if noise is normal. They verified that it's not so, they ordered new shift linkage kit with a newly designed boot. Scheduled for install next week, will post results.

Humm ... wondering how the shift linkage and boot have any association with gear grinding in all gears? Interested to see if that fixes what you're seeing.

I havent any any issue with gridning gears, drive my car all year even when its cold. I only notice it is notchy when cold and will sometimes make me grind the gear myself b/c it is notchy and i release the clutch too quickly. When warm it is smooth. Might be defect and should be covered if it grinds even whem warm and not user error.

Hi ronnier2,

Keep me updated on how the repair goes. I'll be around if you need me.

Lately I've noticed that my 2016 GT with 1200 miles will grind into 2nd gear when cold. After it's warm, it's smooth as butter. I know when cold your shifts won't be smooth, but it legit feels like metal grinding only in that gear.

This is my first manual car. Is this normal and is this damaging to the trans?

How far are you pushing the clutch down when changing gears?

My 2016 V6 also developed a 1-2 grinding shortly after owning it (maybe around 500-mile mark) and sometimes even lock-out.

Yes, I push the clutch to the floor and holding it there while doing 1-2 upshift. Since I noticed the grinding/lock-out, I always make sure to hold clutch to the floor while making 1-2 shift in a very deliberate manner. Even so, I can still feel the grinding (most of times) and sometimes lock-out. When grinding, the feeling is like you try to shift without pushing in the clutch. As a result, I have developed a habit of being super slow/deliberate in 1-2 upshifts. Oh yes, if I double clutch in 1-2 shift, then it is better (but I don't know if this is b/c of better rpm match or b/c of double clutch taking longer time).

Also, my 5-4 down shifts are not smooth. Even with double clutch, I can still feel something (not grinding, but rather a very notchy feeling). But I have learned that if I blip the rpm super high (much higher than the expected rpm in 4th gear, taking into account that it will drop a little in time), it drops in 4th gear better (but there is still a notchy feeling there).

My 3-2 down shifts (always double clutch) are smooth so far. All other shifts (2-3, 4-5, 5-6, 6-5, 4-3) are fine too.

Also, when I hold my shifter to the left, I can hear a buzzing/humming noise, and I can produce this noise every time, both in neutral at stop light and while moving in 1st/2nd gear. One I do 3-2 downshift, with double clutch, after blipping the rpm, when I push the shifter to the left for 2nd gear, the buzz/humming turns into a pretty loud high-pitched noise.

Again, the clutch is pushed to the floor.

I have something similar in my EcoBoost. The grinding, I wouldn't really call grinding in my case. More like the shifter doesn't really smoothly go into place, it has to be pushed. Only while shifting from 1-2; I actually like the notchiness when downshifting, because it allows the shifter to only fall in place when the RPMs are matched.

The main thing that got me in your post is the buzzing noise when the shifter is pushed to the left. My car has had that since I bought it. All the other issues have either disappeared or I have adapted to them (I'm almost 800 miles in now) but that buzzing sound still persists. It's pretty faint now, though. Slowly going away it seems. Or maybe I'm just subconsciously tuning it out. It also used to escalate into a rattling noise sometimes when I stepped on the gas. That's gone too now.

I think my 1-2 shifts are indeed grinding, at least it feels that way. It is like something is preventing it to go to 2nd gear.

Sometimes I think maybe the synchros are bad, or the linkage arm is faulty; but to be honest I don't know. Will bring it to the dealer later this week and see what they can find.

Definitely feel that resistance you're talking about, so I guess I got around that problem by just letting the shifter take its time to fall into place. Don't hear any loud nasty grinding even if I do try to force it though. It was messing with me so much eventually I decided to just let it do its thing, and by the time I go for my first oil change, when everything is nice and broken in, if this or anything else still bothers me I'll have them look at it then

Yea it's more notchiness than grinding. Once the temp is above 45 degrees, it's smooth as butter at all times.

 

[paul123]

I am thinking the gear oil is too thick at lower temps, and the syncs are not able to spin freely resulting in notchy, and even grinding (possibly damaging a sync) for those that force the shift. Maybe I will buy a quart of Ford OEM gear oil and stick it in the fridge , and see what happens to it.

 

[mustang_guy]

Ive had various manuals over the years that either get super notchy/crunchy or have grinded in cold weather. Typically a high quality aftermarket fluid change fixed it. Working at dealerships over the years some cars have either a shift fork issue, synchro, shifter cable, hydrolic or linkage trouble.

 

[Horse]

Sometimes I wonder if the cause of this (grinding) is inside the transmission (shift fork, synchro, etc) or outside (shifter linkage, etc). If it is outside and can be cured by a shifter upgrade, I will be more than happy to upgrade the shifter.

 

[paul123]

I think a shifter upgrade is more for power shifting, where you can get flex. For leisurely shifts, you should not get any grinding, particularly when the transmission is warm, such as after 20 minutes of driving. You probably should not get any grinding when cold either. In these cases, the gear oil is suspect.

 

[Horse]

Yes, leisurely shifts are all I do, but grinding is still pretty noticeable even after 20 minutes. I agree I should not be getting grinding period, but reality is different.

I mentioned shifter upgrade because the stock shifter is body mounted and can get flex. Sometimes I tend to liken the grinding to something somewhere is not aligned correctly due to flex and hence preventing it to fall into gear smoothly.

in this case, it sounds like a worn sync. does it still grind with a double clutch?

You could upgrade the shifter, but I suspect the problem will continue, and you will mainly just lighten your wallet $500 or whatever.

if its conspicuous, you may be able to get it fixed under warranty
