    Break in period. Any input?

    Comming up this Monday I will be getting my wrx back from the shop. Ive had the whole transmission redone down to the t.
    Just wondering if anyone else has done this and if so what are the reommended rpms and mileage before its nice and set in.

    Like I said complete over haul. Gears. Shafts. Syncros. Clutch. Fly. Etc.

    Car is an 02 wrx. All this in a BA case.

    I'd treat it like a new car since you cannot decouple the motor from the gearbox, and the gearbox is in essence new. Therefore I'd follow the usual 1000 mi break in recommended by Subaru.

    From the manual it says to change gear box oil at 100 miles of break in period. And then again at 1000 miles. Along with a general clutch break in period of about 500 miles. Does that sound correct?

    The manual says 100 miles and then 1000 miles for gear oil? I did not do this when my car was new.

    Maybe it wasnt the manual but I know I have read it somewhere. I know at lleast by 1000 a change is recommend to rid the internals of any shavings from the break in.

    I don't think Subaru recommends this, and they make the most Subaru gearboxes. In any case a change of gear oil certainly won't hurt; it's just a pain and expense, that's all. Grab a spare crush washer for the drain bolt and check the torque spec.

    So you think a 1000 miles will be alright? Thats all city and lots of shifting right?

    Unless the people rebuilding the gearbox left several kg of debris in there I don't see why not. You could ask for their recommendation as they did the actual work I suppose.

    1000 miles easy is what I've always done and always will do. Never had a problem on any motorcycle or car I've owned. And I've owned a lot of them...

    So 1000 miles easy on a break in. Did you change any fluids?

    Also, how do you feel about riding long in one gear? Say fifth gear on the high way?

    It's definitely not in the manual, and wherever you read that is somewhere that has bad information, and I'd be hesitant about following anything else you read from there.

    +1 there shouldn't be any reason to change the gear oil any time soon. You should only have just a very small amount of metal flakes/shavings/bits from the normal process of metal surfaces under extreme stress meshing themselves together. Those should be small enough in number and size that you shouldn't have any reason to change the gear oil before the mileage specified by Subaru for the first change. But definitely ask the shop what they think. And I'm also assuming you had a standard set of parts put in and not straight cut gears or anything like that.

    There's no reason to be concerned about that like there is with keeping the engine RPM the same for an extended period. I just wouldn't be launching the car (not that I ever would anyway personally), putting extreme stresses on the gearbox (like doing a track day, auto-x, or visiting the drag strip), or just in general driving it really hard.
