Okay, first off, just because this is a forum doesn't give you any excuse to be completely incoherent. It doesn't take that much more effort to type in an understandable manner, and you will be much more likely to get help.

That said, how many miles are on the car? The only time I ever had a truly noisy transmission is when it blew all the fluid out a seal on track. If you haven't checked in awhile, make sure that there is still enough fluid in the trans. If the bearings are gone (mine were, but lasted another 5k miles before I started losing gears) a new transmission is about the only option. M42 getrag 240's aren't terribly hard to find though; I got one for $100 and another for $200 after discovering the first didn't have a 3rd gear.

You can pick the rear output shaft seal out once you get the driveshaft unbolted & out of the way.  You'll need an impact wrench to get the output flange off though.

It'd be easier to just refill & drive as needed, then tear into this when you get to your garage.  Gear oil isn't necessary.  In a pinch you can use ordinary motor oil.
