It sounds like this only when you engage the forward or reverse gears. It acts as if it is not getting any fluid from the gearbox. All hoses were already blown out and checked to be sure they work. I am confused. At first it sounded as if the gears were grinding or the wheel motor was bad. That is not the case. It has to do with the gearbox as 3 of the pistons inside were stuck. (My bad if that is how they were supposed to be.) What should I try next? Thanks!!!!!
