Subaru starts out slow from stop - help?

I bought a used 5-spd. Subaru a year ago and now all of a sudden it starts off really slow from a complete stop. Once you get to 30-40 mph it's okay but it just takes a long time to get there. No revving rpms, no bucking, no smoky smell, nothing but the slow accel. Had the clutch replaced by a mechanic I trust and no change. Local Subaru service dept. had a look and says I probably need a whole new transmission at a cost of $7000! I didn't really trust them even before this issue because any time I have gone there they find literally thousands of dollars worth of things I "need to do" and it took 4 tries to get them to order some simple trim parts correctly. But they're the only Subaru dealer near enough. Anyone had a similar problem, or worked on Subaru's and know what this might be?

    More than likely it may be the transmission. The good thing about trim parts is its a Subaru. I have ordered a simple belt molding for a door & had to order it like 4 times before the correct part showed up. I guess some stupid Jap kept putting the wrong part in the box. Part number was correct on the box, but had the other side in the box.

    I would check the exhaust system myself, those cat converters tend to plug up as well. You can have your mechanic buddy disconnect the pipes at the manifolds & go drive it & see if it has power from hell now.

    I would check the fuel system as well. Without looking at it, I cant test anything. I wouldn't say the dealership doesn't know what they are doing, there are really good technicians at a lot of the dealerships. It could be the torque converter acting up or one way clutch slipping

    But they are like any dealership. You or any other person would fuss & moan & ***** if we didn't tell them that their brakes are gone or coolant is leaking or what other problems may be happening. Me, I write up pretty much everything, I really could careless if people buy anything or not, not my car. I really don't care if the brakes fail & they kill someone or the tie rod breaks & they hit the ditch at 70MPH.

    As long as I wrote it down on the paper & the customer declined it, I am no longer legally bound to that car & any accident that may occur, isn't on my hands . But the first time someone kills somebody, you can bet the owner of the car will be screaming no one told me my breaks were gone, etc,etc. Just so they can point the blame at us technicians.

    but I haven't seen a Subaru come in to the shop with less than $1500.00 in repairs. They are ok cars, nothing to write home on though.

    They do have head gasket issues, CV Boot issues, throttle body issues, cat converters plugged up, wheel bearing problems

    Both of my Subaru's had issues right after they hit the 50k mark. Turned both of them in.

    Though I do love them, repairs on these cars can be very expensive.

    Every car will have some sort of issue when they start to hit high mileage. The key is to maintain them and have them inspected each year by a certified mechanic.

    In your case, you don't know the history on the car, unless there is proof/papers showing all maintenance work on the car.

    Also, when looking for parts, don't just buy from the dealership. They will rip you off anyway.

    Try RockAuto.com for your parts. They are cheap and quick to shop.

    We use them all the time for parts on our cars. Foreign and domestic.

    1. Have a shop do a fuel pressure test at the rail. Also a compression test and check for vacuum. Not familiar with Subarus but if they have solid lifters, have the valve cleareances checked. Replace the injectors.

    2. Have a scanner plugged in and have it read codes when you are driving the car. Have a shop test your MAF and MAP sensor.

    3. Check your clutch again. Start the car, drive to a level ground, stop and put the car in second gear. Without stepping on the gas, slowly release clutch. Car should stall.

    this is just a thought but maybe the transmission is low on fluid and causing the gears turn slow ! are you starting out in 1st gear ? if your trying to start out in 2nd then it,s going to be a slow start out !
