Default Lots of transmission noises on '09 WRX wagon?

Since this is my first Subaru, I'm not sure if most of the noises are common.

'09 Subaru WRX wagon (01/09 built)
2,100 miles, engine, transmission, and diff oil all changed at 1,500 miles

First of all, there's this sort of weird "grinding" type noise when I lift off of the throttle while in lower gears (1, 2 and 3) and may possibly be present in the higher gears, except when in higher gears the speed and tire noises may be drowning it out. Does not sound like gear grind, more like two pieces of metal sliding past each other as they spin. Noise was present AFTER I installed solid urethane shifter bushings on the carrier. Car came with the SPT short shift kit. Noise has been getting progressively more pronounced. When noise is present you can kinda feel a slight knock on the shift knob.

Then there's a "knock" type rattle upon acceleration, again mostly in lower gears, and mostly right after you engage the gear. Once car is in gear, getting back on throttle does not produce the same noise. Noise is fairly subtle, again, when noise is present I can feel a knock or vibration in the shift knob.

I've taken off the boot and inspected, and I suspect the connection between the selector rod and the stick may need to be re-tightened or at least torqued down to spec and blue-loctited. I did remove the rubber boot underneath and re-installed the plate once and the noise "lessened" for a couple of days. Maybe the bracket and boot needs to be torqued down as well. I had suspect it was the exhaust/header hanger that hung down from the transmission/carrier arm bracket but that's plenty tight.

So I'm asking you guys. Are these noises common after break-in on a relatively new Subaru? My prior cars are all insulated to the hilt and typically all I hear are a muted exhaust tone and MAYBE some tire noise. Could use some "peace of mind" if these are just the common noises you would expect to hear from an '09 Suabru WRX Wagon.

I think what you are describing is pretty much normal for these cars - especially after replacing bushings. When my STi had about 15K mi I replaced all the shifter bushings and noticed very similar noises I hadn't heard before. I have also replaced the trans mount, rear diff bushings, crossmember bushings, as well as diff lock bolts which have increased the noises up another level. I like it because I can feel and hear what the driveline is doing. If you are still concerned I would do like you said and double check everything to make sure all the nuts, etc are tightened properly and not hitting anything. If they are all good, just hit the gas and enjoy the ride. Subies have all kinds of strange noises which remind you that these cars are different and made to take the abuse.

Easy man, I had a factory defect in my transmission and had it rebuilt with new oil at 1,300 miles in my 08. Thing runs like a charm. NOT factory oil, sure it sucks, but it was free and until I have any issues I'm not touching it. It shifts smooth and easy without any grinding or other less than ideal sensations or sounds... Maybe this winter when it starts to suck and not want to shift in the cold I will swap it...

Allow me to bring it back on topic. When they did a rebuild and put different oil in, it did NOT cause any additional noise from my transmission....

Sorry to go off topic.

Mine (09' hatch) does it too. It has since new.

The noises (I assume) are from gear rattle as you decellerate, they will ride on either side of the gear face in an alternating fashion.

The 'rattle' you hear on takeoff is likely to be the clutch springs. Mine did it as well (it was noticable in the garage when letting the clutch out to back up with the windows down).

And for the record, it's a hatchback

The clicking noise happens on my 09 sedan as well. It's been driving me nuts lately - seems like it's getting louder but probably just my imagination.

I have the Kartboy STS/bushings done as well.

this is, AGAIN....100% ****ing irrelevant to what happened to the OP

the OP may have put the WRONG ****ing lube in the trans and maybe the blokes who did YOUS put the RIGHTY **** in it

THAT is ****ing RELEVANT

maybe you should just stay OUT of things that may not concern you and YOUR condition....and learn something in the process

which is the bloody reason I asked what I did in post #3

I am not even entirely sure what was put into mine, but yet you are making a huge assumption they put the right stuff in mine and wrong stuff in his. Not only that it is a HUGE leap to assume he put the wrong stuff in and that is the EXACT cause of his issue. What if it was the EXACT SAME OIL...

Relax man, we are all on this thread to try and help him out. Nobody wants to make enemy's here. I'm not trying to start a fight, would appreciate it if you would ease up and be a little more considerate of the OP by providing constructive comments instead of flaming me.

Noise was present prior to the change. Post change the noise actually lessened.

As to what fluid, I'm not about to get into THAT discussion again. Based on what I know, I'll just leave it at the fact that 90% of the fluid available on the market today, comes from 3-5 different "companies" that make them, and it will come from whatever "company" running the best deal at the time. They're just packaged differently and with different color added to differentiate. Formulation is IDENTICAL if they're the same weight. Anyone else telling you otherwise, probably doesn't work in an industry where they had to actually buy AND sell lubricant.

Sorry, couldn't resist. Compared to what I'm used to, the WRX "Wagon" is down-right cargo van like in terms of size and utility. That, plus the fact that it's got more usable room than most of the typical small sized SUV without the weight and the ride-height qualifies it as a wagon in my book.

Or "touring" in a parlance I'm more familiar with.
