[86Tony]

Just got a call from the dealer.

It turns out its something to do with the input shaft on the transmission that's making this noise. Its weird, because I never had any shifting issues or anything of that nature.

They ordered a new transmission and I'll be getting it replaced May 13.

This sucks. From what I understand, its safe to drive. It just sucks.

mine has had this too since probably.... 8k miles. I dont think its anything to worry about. And i'm honestly really surprised that the dealer is straight up replacing the whole trans for this "issue"

part of me thinks the noise will still be there(if they dont change out the clutch/pressure plate as well), or come back after several thousand miles. I'm genuinely curious. please report back.

Will do. It doesn't sound like a healthy noise and no one on the forum as said anything about it. I figured while I still have the warranty I might as well get it looked at.

True, but thats probably a good thing then, that nobody has been saying much else because if its a sign of imminent failure, i'm sure we would've heard about it a lot now. most of the complaints is the notchy-ness and "grinding" (quotes because i think some people might be mistaking notchy for grinding. Some.... not all)
but actual failures of synchros/gears are basically limited to those running over 300 rwtq. i'm sure there has been a few bad ones out there though.

Understand that much more goes into the shifting system than the clutch and FW.. specifically input bearing, input shaft, and others that dude talked about. An off-kilter input shaft can oscillate and throw the otherwise well-functioning FW and clutch assembly off balance, thus chatter.

[Bobblehead]

New transmission is in. So far there hasn't been any chatter noise upon a cold start (35F this morning) and normal idle.

I only noticed a brief noise when the A/C compressor kicked on after turning on the heat. I guess the problem is fixed. The dealership sent the defective tranny back to Subaru. I asked the parts/service rep if Subaru would say what failed or caused the failure, and he said no. If there was an issue with it, the only way they would know is through a bulletin or TSB.

I'll keep listening for the noise, but with it finally warming up outside it might be impossible to mimic the conditions.
