I have an 08 Heli 5k lift. I had one of my drivers who claims to be an ace mechanic remove the flywheel weight and install the factory upgrade because the teeth kept breaking off from the ring gear. Anyway, when he put the engine back together with the transmission the machine will not move. I have a feeling that the pump is damaged inside of the transmission. I have removed the engine and the torque converter and I need to remove the trans from the differential. Do I need to remove the axle shafts or will the transmission come right out. Thanks for any and all help.
