tnichs13 Posted January 25, 2015 Share Posted January 25, 2015 Well, I may have bought myself a lemon. Bought this car from away and was stupid enough to trust the dealership in montreal. They got me. Was immediately hearing a grinding noise from (what I thought) was the transmission, emptied the fluid to find it sparkling with little chunks of gear. Perfect. Luckily Subaru Canada decided to send me an entire new tranny despite the fact that it was out of warranty!!! Installed at the Subaru dealership, and what do you know, the grinding noise is still there. Only after purchase did I find out that this is the SECOND tranny replacement that has been done on the car. One at 90k kms, the second now (120k kms). I have a feeling that whatever this noise is, it's what has been eating tranny's, but the dealership, my local mechanic and i are all pretty perplexed as to what it could be. Mainly low revs, accelerating, or letting off the gas. Any thoughts would be greatly appreciated! Link to comment Share on other sites More sharing options...
Lafta Posted January 30, 2015 Share Posted January 30, 2015 Bump! I have the *exact* same sound going on in my 08 Spec. B. Mine occurs in 2nd gear only, upon acceleration only. Anyone get it figured out? Link to comment Share on other sites More sharing options...
Lafta Posted January 30, 2015 Share Posted January 30, 2015 Seems there all kinds of noises associated with the Subaru transmission. A lot of folks calling it "normal" and "get used to it". Take this link for what it's worth... http://forums.nasioc.com/forums/showthread.php?t=103494&page=17 Edit: The sound I'm getting is what the OP has going on in his vid, not the various sounds (and descriptions) in my link above^^.

jam007 Posted February 2, 2015 Share Posted February 2, 2015 Or the transfer gear bearings are going bad Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted February 2, 2015 Moderators Share Posted February 2, 2015 Brand new transmission and same noise likely means that the issue is outside of the transmission itself--not that the car is "eating transmissions". Does the car just have aftermarket bushings / engine mounts / pitch stop? All of those can contribute to noise that may sound like somethings wrong (grinding / rattling type noises). If you are not used to aftermarket bushings you may thing that something is wrong, when you are actually just hearing normal transmission noise that is now being transferred into the cabin instead of being isolated outside of the cabin by soft rubber bushings.

Lafta Posted February 2, 2015 Share Posted February 2, 2015 Just had my trans. and differential oil(s) changed out. There was but *just a bit* of shavings on the magnetic drain plug. The sound remains, and I have resolved to live with it. Hopefully it's just "normal transmission noise", although I never heard it in my 05 LGT. The "sound"---- FWIW, the sound comes on at accel. and decel. in 2nd gear, and ever so slightly in 4th. Link to comment Share on other sites More sharing options...
thunderfox Posted February 2, 2015 Share Posted February 2, 2015 My BRZ (4k miles) used to honk (like a goose) and clink when downshifting...FWIW it seems like Subaru's 6MT just makes a lot of noise. Link to comment Share on other sites More sharing options...

Lafta Posted February 2, 2015 Share Posted February 2, 2015 Yes darn, can't hear much in the video. The guy does 2 takes in the vid, both of them shifting from 1st to 2nd. The 2nd take can be heard a bit better, and it helps if you crank the volume way up, and hold your laptop next to your ear Link to comment Share on other sites More sharing options...
tnichs13 Posted February 6, 2015 Author Share Posted February 6, 2015 Ya sorry, the vids aren't optimal. It is definitely a strange noise, I've had some buddies who are familiar with the 6MT out for drives. Latest update, throw-out bearing would appear to be shot (fantastic... we just had the tranny out). Seems like there are multiple issues. Trying to figure out which are related and which may be causing others is not easy! Link to comment Share on other sites More sharing options...
tnichs13 Posted February 6, 2015 Author Share Posted February 6, 2015 transfer gear bearings are a good thought! When mine started it was only in second as well. Spread to other gears. I may just drive it too if I can't resolve this soon... One year warranty on the new tranny right? Link to comment Share on other sites More sharing options...
Lafta Posted February 6, 2015 Share Posted February 6, 2015 I tried slightly moving the shifter to the left or to the right, while in 2nd gear. This did seem to remedy the sound a bit volume-wise. It' still there, but a bit quieter. tnichs13, do you have a short throw shifter (as I do) ?? I wonder if it has something to do with this, the short throw shifter. Hmmmm... Anyone, any thoughts?

Lafta Posted February 7, 2015 Share Posted February 7, 2015 I managed to track down the previous owner, and in his words... "The shifter noise was less noticeable before I had the short throw shifter and polyurethane shifter bushings installed. However, it was there since the day I drove it off the lot. I actually went back to the dealership when I noticed the noise (which was only in 1st and 2nd). They assured me that it was normal on all 6 speed equipped cars due to the straight cuts gears in 1st and 2nd. The noise didn't seem to change at all during its life so I was never concerned. That being said, if you reinstall the rubber bushings it will reduce a lot of that noise." So there I go....Drive on, now at 56 k mi. Link to comment Share on other sites More sharing options...
tnichs13 Posted February 8, 2015 Author Share Posted February 8, 2015 Don't have a short shift in mine! and the noise is now just as bad in 3rd and 4th. I'll likely just keep driving too! Link to comment Share on other sites More sharing options...
