I know I'm not supposed to, but Sonic transmission grinding a deal breaker...

May the Sonic forum gods forgive me

I am trying to figure out whether ALL RS Sonics are affected by the 6 speed grind? The reason I ask is that I basically have my heart set on one (going in to test drive/seal the deal tonight on an old stock 2013 that is brand new for cheap). But if the grind happens to ALL of them, I can't fathom purchasing one. I like to have fun with my cars, including aggressive driving. If I can't shift above 5k rpm without 1st to 2nd grinding, it is absolutely a deal breaker.

I have no issue if the problem can be fixed. I have no problem changing out the factory gear oil to syncromesh (a common trick in my old Suzuki Swifts). I have no problem getting the tranmission warrantied if it fixes the issue.

But if it is a flaw from the factory with no way to fix it (hell, I'd even pay for new internals in the transmission eventually if it lead to a fix), then it seems like a bad idea to purchase.

Thank you for your help Sonic owners, I hope to be a member of the club soon

My sonic is at 20k miles and I get no grinding, all I get is the 1st-2nd grind when first starting it.

So you do get grinding?

Just when i first start the car, it's common with manuals from what I understand. Gotta get the juices flowing

14k on my rs no issues

I have the LT and have never experienced this. Just fully press the clutch

I think that most of the issues with the grind are blown out of proportion. Definitely not all 6-speeds are exibiting this issue.

Now, having said that, I've experienced it in mine a couple of times. This happened within the first 5k miles or so and hasn't come back since. I drive spiritedly and shift fast, but I don't slam the gears.

My 2014 rs gets the 1-2 grind, but 'above 5000' is a poor way to describe when it happens. It is very specifically when I'm launching and run it to or almost to the limiter in 1st. Which sucks when it happens, but i have found you don't want to go past 5k while launching anyway, because there is no additional power and it slows you down. 4750 - 5k is ideal shift point for continuous pull. I've never had it grind shifting below 5.5k. You have to learn to drive around it, but it is an awesome car, and while i hate the entire world when it happens, it's certainly not a deal breaker.

Interested as well to know if changing fluid helps.

Thank you for the response, that is the most apt description I have heard of the issue yet. Has anyone ever tried motor/transmission mounts to solve the issue? If it only happens on a hard launch, it may be too much movement.

My understanding is there is a cable adjustment TSB, which maybe too much engine movement causes issues?

There is plenty of info on here about the grind (from oil changes to cable adjustments to the affects aftermarket clutches has in the shifting), you have 7 more posts before you have full access. Knock them out and start to use the already available information. Welcome to the forum.
