5th Gear grind after maintenance

USMCram

Hi All,

I recently had my flywheel, clutch, CSC and Master cylinder replaced all at once.
Switched to the JWT lightweight flywheel and clutch, as well as the CMAK csc replacement.

After doing so, with zero hard driving, I'm grinding in 5th gear, up and down shift.

Flywheel chatter is also very noticeable when in 5th gear.

Taking it back in to the shop, but they're already saying it's likely that my syncros are screwed.

My question is, can doing these replacements cause the issue, or is it not likely something that's wrong?

Thanks.
