Have to agree...the fact that it doesn't do it in reverse makes me kinda worried though. If it was the clutch it should do it even in reverse...if you really wanna test it, get some open area, put the car in reverse, let the clutch out all the way and get rolling, then just step on the gas and see if it does anything weird.

I can't imagine the transmission going bad so that the synchro's on every gear are bad...
