This is a rebuilt Ford NP435 4 speed transmission. It has not been installed since the rebuild and I don't know how long it has been since the rebuild took place. This is a heavy duty four speed with a granny gear that just creeps along. These were a mainstay in the off road vehicles. Ford used this rock solid workhorse in their heavier duty vehicles. This is being sold "as is best offer" colorado springs 719-229-6378
