[Shotimes] transmission problem?

[Dynon007@aol.com]

I let my friend drive my car... big mistake. Anyway he said he was driving 
down the highway with the climate control airing it out. Which I never do 
cause its sluggish and sometimes makes weird noises. Anyway he said he put it 
in forth at 70 MPH and heard a big pop and smoke started coming out of the 
back. He pulled over and looked and everything was fine. He drove it back to 
my work, and now it starts to make all kinds of sounds above 4000 RPM. If you 
go to 5000 RPM it starts like clicking sounding like a spark. And a glossy 
black fluid is coming off where the transmission check plug is. When I drive 
it though it stills shift fine and goes into gear really smooth other than 
first which always used to grind but I was told that was my clutch just not 
disengaging or my synchros. I dont think the transmission is gone cause it 
still drives pretty much perfect, could it just be a leak in the transmission 
or does anyone think anything else?
