Converter problems my friend, shaft splnes broken.inside torque converter.
It's in "reverse."
has a full charge won't go forward or reverse
Your arctic cat 580 will go in reverse and not forward because the reverse linkage is okay while the forward linkage is not.
it will drive but when in reverse it wont move
I have the same problem with my 92 Mazda 626, have Not found a solution yet.
trans is slipping
This depends entirely what type of car this is but: There is a serious failure of brakes or other safety equipment.

does it shift into reverse and wont drive? if so its your tranny it needs to be replaced
If its a chrysler you might have a bad solenoid pack
Try uncrouching ;)
If you have an automatic transmission, it probably has a forward clutch/band problem.
