6th gear grinding

[D-VO]

Hey all

I normally skip gears as a drive and typically shift 1, 3, 6. A couple of days ago I revved 3rd gear out to about 5k rpm, shifted into 6th and had a really bad grind. Last night I decided to check any other combinations that would create a gear clash and found that generally any gear into 6th past 5000 rpm would grind. Is anyone else having this issue?

you're over working your syncros. try 1-2-3-4-5-6 or at least 1-2-3-4-6

As I understand, 6th gear is less that 1:1, like an overdrive. Reving the car real high then is not what 6th gear would want in order to engage smoothly. I don't really see what advantage skipping two gears has, from 4th to 6th? If you don't want to shift, why not get the automatic? Anyway, I believe the main problem is that you are not matching the rev's correctly - that's why it's grinding.

Cars have gears because they need them , 1-2-3-4-5-6 Learn to shift in that pattern and your car is asking you wtf your doing "grinding noise"

I've always skipped gears in all my cars, so I figured it would be fine in this one. I skip gears because the engine has enough torque to accelerate well in the rpm range at which it falls when I skip gears.

I guess the problem now is since I'd like to race, the 6th gear grind will soon turn into a transmission rebuild. Thanks guys.

4th grinds every single time over 5k RPM unless I take a good 2 seconds between clutch in and shift.

Regardless of how you shift, you should not hear any grinding. Especially on a new transmission. Though shifting to top gear from a higher rpm will work the synchro harder, it should not create an issue with grinding.

I've had 3rd and 4th gear feel crunchy on shifts, but no grinding per se.

hmm maybe you should change your shifting habits or transmission fluid

Because when you've reached the proper speed for the road you are on in 3rd gear why should you have to go through 4 and 5 just to end up at 6 at the same exact speed.

OP - I've noticed the same issue. Even accelerating onto a highway up to speed in 5th and going to 6th quick once I reach cruising speed. I've learned to only go into six "casually". I.e. once I've reached speed in whatever gear cruise for a moment before shifting, and if I'm coming from really high RPMs I'll give the engine a couple seconds with the clutch in like someone else mentioned to come down before putting it into 6th.

Change .. your .. shifting .. habits.

You're being lazy. Not clever. Don't take offense to this - because you're not driving it as you should be.

If it's not reasonable to do this .. I recommend purchasing an automatic.

If you're skipping gears, you have to shift slower. Gotta wait until your revs drop some more or you'll grind.

I can shift into 6th well above 5000 RPM without any problems..but that is because I shifted from 5th...If I skip a gear (typically go from 4th to 6th) I let the engine wind down and I move it into 6th then when the engine speeds would match the gearing for going X km/h. You are just shifting bad.

Also, D-VO, "I skip gears because the engine has enough torque to accelerate well in the rpm range at which it falls when I skip gears." You do know this car has minimal torque right?

It's a way your car is telling you that you are doing something wrong and your driving habits are hurting something. I'm perplexed on what advantage skipping gears is.

a) If you're just trying to get up to speed to cruise, skipping gears would put added wear on the higher gears to get you to the speed a lower gear could accomplish with significantly less wear. It's like you're getting a smaller guy who could lift 100 lbs to lift 150lbs instead where you could get a bigger guy who could lift the 150lbs easily and not break a sweat.

b) If you need to be in 6th gear to race, it wouldn't be territory where the 86 would feel most at home anyways on a high speed course.

I agree your driving habits gotta change to make the most of this car AND maintain the longevity.

Why is this so hard for people to understand? If you go 1-2-3 and are at 50mph on a 50mph road why the hell would you go through 4-5 to get to 6 all while still at 50mph???

As mentioned many times now, just have to shift into 6 more casually. If you raced up to speed give the engine a moment with the clutch in to drop the RPMs before shifting into 6.
