1999 nissan pathfinder jerks and stall when slowing down or at red light

YOU might find its due to the Auto Matic gear box as when you slow down at the lights or brake hard to stop the auto box should brake free at about 600rpm as to allow the car to stop but the engine to keep idling,but the drive bands in the gearbox and the pump which operate them are not braking free so its like, in a Manual g/box driving and stopping but leaving the clutch pedal and not pushing it in so the car stalls,
SO you may find that the next time you are driving it and come to the lights just try putting it in NEUTRAL gear before you stop and try, if it ok then get the g/box serviced . RON
