Default In Dire Need of Someone Help To Diagnose/Possibly Fix Issue- 2007 Impreza 2.5l

I've been having this issue for almost a year now. The car is an automatic with 82k miles. When it goes to shift from 2 to 3rd or 3rd to 4th (I can't really tell it seems like the 2nd to 3rd the most) the shifting does not always seem right...I guess that's the best way I can describe it. The rpm's will also seem to wander sometimes randomly it seems. It drives fine on the highway and shifts in higher gears fine. It's almost like it shifts early and kinda drops into the next gear. It doesn't really make any funny noises or anything. The acceleration just seems a little off as well. Someone told me it could be the timing belt, someone said a sensor, someone said solenoids...I've cleaned the MAF sensor as shown on the forums. It is so hard to explain without driving it which is why I'm looking for someone close to Gardner, MA who thinks they may be able to help figure it out and possibly even fix it if I pay you. Thanks for any help in advance.

Pull the transmission dipstick out and check the color and if it smells like burning. If its dark and has a burning smell, your clutch pack might have gone to **** and is slipping, causing the RPM to go up or down without actually transferring power to the transmission.

If its not that, i would think it could be the selenoids for the transmission, but thats a long shot.

i will literally drive anywhere within an hour or two if someone thinks they can help me diagnose and fix this i just don't trust the dealership after what they've done to me and pay for someone to fix it.

It sounds like your transmission is slipping. If when it goes to shift it revs up a little and then goes into gear then that gear is slipping. It has happened on my Explorer and my mom's TL. The 4 speeds tend to be very solid though, so I'm not sure whey this would be. Does it do this when you're shifting manually too?

If you have no warning lights, I doubt it's a transmission solenoid issue. If your fluid is clean and clear, I doubt you have a burned clutch pack.

The description of your symptoms is too vague to hazard a good guess. If you have a consistent 2-3 upshift issue, it could be wear in your high clutch. A 3-4 upshift issue could be a 2-4 clutch, (usually affects 1-2 as well) or you may have a low clutch releasing prematurely. There are a lot of other variables to consider as well (line pressure, etc.)

no warning light, the fluid seems clear and clean. it smells funny but i really don't know what transmission fluid is suppose to smell like. its very odd, it just seems to shift fine sometimes, but shifts strange sometimes like it shifts into the next gear way before it should i don't know how to explain it.

Transmission fluid is the worst smelling stuff on board although the hydraulic fluid in shock absorbers is pretty rank too!

Have you brought it to a dealership? Back when I was working at a dealer they had ref lashes that would sometimes fix issues like this.

I'm not to familiar with the 2.5i auto tranny but if its anything like the 4eat then the left side of the tranny (looking at engine from front) is the diff dipstick. The diff fluid should be almost engine oil color maybe a little lighter clear brown.

The ATF dipstick should be on the right side of the tranny and that fluid should be reddish in color and smell terrible.

I'm only stating this make sure your checking the proper place.

I agree with this, it sounds like a slipping transmission as well as one could glean from the OP.

Take it to Wicked Innovation. Normally they take turbo Subarus and make them faster and/or handle better and/or prep them for the track or autocross or rally. They don't do much in the way of N/A stuff because of their situation, but they can at least diagnose the problem for you as they are honest, competent mechanics, and refer out if needed.

Either way it's going to probably wind up at a transmission specialist, but Wicked is honest and refers out to honest competent people so you know you won't be getting scammed. They are located in Manchester NH now.

i drained and filled the transmission fluid it seems a little smoother but still shifts a little funny especially 2nd to 3rd and 3rd to 4th. It just started leaking oil three days ago and I took it to the dealership and they said it was the cylinder head. They had just recently done the valve cover and spark plug tube seals. Are these issues related? Could this be caused by a transmission issue? I've had nothing but issues with this god-forsaken car since I bought it.

"It shifts funny" doesn't describe the issue enough for us to help. When it changes gear do the RPMs surge or go higher and then come back down? Or is the funny biz more of a jolt or a feel? No your cylinder head leak and transmission issue are not related.

yes that what it feels like especially in second and third gear sometimes...it's not always. if feels like i'll have my foot on the pedal the same amount and it goes up then down then up before it shifts. it feels like it shifts clean it just seems like it can't decide when it wants to shift. someone said maybe have the ecu reflashed? or a transmission sensor...does this sound like the timing belt at all?

I also noticed sometimes when cruising from anywhere around 30 or 40 mph if i take my foot off the gas the rpm's feel like they stick, or randomly go up or down. I had a similar issue that felt like this in my SRT-4 and it was a fraying/broken wire connecting the throttle positioning sensor...is there something like that in my N/A subaru too? It feels like sometimes it's fine and sometimes it just does what it wants like the throttle sticks.

the symptoms in this thread seem to describe similar to what is happening

http://forums.nasioc.com/forums/show...e+2007+impreza

can anyone give me more information on if it's a grounding issue? I'd really appreciate any help locally and would pay for your time.

So I took it to the second Stealership closest to me, Village Subaru in Acton, after having had nightmarish experiences with West End Subaru in Lunenburg. I have completely lost faith in Subaru this is two dealerships who have acknowledged a problem with the car, but both have said since it's not throwing a code they cannot tell what it is definitively. So today the bled the transmission fluid and supposedly reset the transmission computer to relearn and it did jack ****. So they play parts darts and just throw bills at me and the problem still isn't fixed. I would never recommend someone buying one of these pieces of **** as long as they live it has caused me many sleepness nights and more frustration than is humanly possibly. I want to take this car and crash it head on into a tree.

I understand your frustration but it isn't too surprising that the dealerships are having trouble finding the cause. Have you tried one of the independent shops in NE that get good reviews around here?
