5th and 6th gear grind...

So fairly recently I have noticed that whenever I shift down from 6 the into fifth it will grind pretty badly into gear...I have my foot to the floor with the clutch, and have even tried double clutching and I am getting a grind 95% of yeah time. If I am accelerating quickly and shift from 4th into 5th it will grind as well. I even just a few minutes ago had it grind into 6th as I was accelerating away...

The car has 43,858 miles on it. My understanding is that there is a 60,000 mile power train warranty. What is the likelihood this will be fixed under warranty? It is driving me crazy and absolutely ruins the driving experience when I'm constantly worrying about shifting...also, anyone have any suggestions? I don't think simply changing the fluid is going to fix this.

You may consider checking the clutch adjustment .....

Maybe bleed the clutch/brake system.

If the clutch adjustment was off wouldn't I be grinding in other gears as well? Out of all my cars with a hydronic clutch I don't think I ever once needed to bleed the clutch.

Bring it to the dealer. But first remove any performance mods. I got a new transmission under warranty but I only had like a couple thousand miles.
Had exactly the same problem. Fifth gear grinding going in or out of gear.

Dealership confirmed a bad transmission. Getting a new one installed next week. If anyone is having any major grinding issues take your car in and have them replace the trans!
