Cause it Fails! Either the transmission is shot or the parking brake is stuck on.
maybe the transmission linkage, throw out bearing or modulator
If you have an automatic transmission, it probably has a forward clutch/band problem.
Brakes locked?
Check the fuse/circuit breaker. If they check okay you may have a mechanical problem.
this is a typical problem with berettas, for some reason the bands in the transmission will not hold out after several miles are on the car, have the bands tightened or replaced, and you wont have any more problems
you have to put your handbrake on and then it wont roll down the hill
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.
why reverse wont go in on 2004 town car
truck will only go forward not in reverse does this mean the transmission is gone
Then remove the parking brake........
Gear up then
