    Hello again new day new problems! have an annoying clunk when i drive not over bumps or anything but when i accelerate and changing gears ? I think it comming from the passenger side ? Both wheel bearings are new no play in them but driver axel on the left side has some play in it ? That cant be good ?

    Sounds like it happens with loading/unloading of the trans, and while the axle has some axial play, it doesn't have any slop in the splines it looks like.

    Just curious, have you check the nuts under the 5th gear cover? They might be loose and allowing some slop inside the trans.

    Does it happen on every single shift or just certain ones? And does it happen every time you accelerate? What about deceleration?

    it happends most of the times and sometimes it doesnt happend ? Are those bolts easy to get to ? I drove it on the highway but no sounds except when i was down shifting . That sound started a while ago when i was in first gear and rev it up to 5k and launch it then slammed in to second gear bit it wudnt shift LOL

    It could also be a partially broken shift fork, the remaining piece of the fork might be rattling around in there.

    The 5th gear cover is easy to get to, it's right on the end of the transmission.

    I had a similar issue on my gsx. Check your trans fluid and check for metal shavings. My issue was the front diff was shredded.

    Just so you're clear, the nuts I'm referencing are under that cover and attach to the actual shafts.
    @boostdawd is right that it may be more serious so a flush and inspection of the fluid is a good starting point.
