Forward clutch failure. Needs a overhaul.

the thing is that it worked 2mins before

Could be one of two things: sticky valve, or blown seal at the clutch pack. If the fluid was very dirty, I'd bet on a stuck valve. Try idling it for a while to get the trans up to temp and see if you can get it to pop into drive then. If you can, run the piss out of it, then change the fluid again. Then run the piss out of it some more.

Failing that, get a book and start troubleshooting, or swap it out for a reman.

fluid wasnt real dirty or smelled burnt

and if it is a valve how would i fix it

Easiest is to replace the valve body.

There are quite a number of failures that can come on suddenly, a blown seal (or broken splines or broken clutches or whatever) being one of them.
