What the heck. I just unbolt it and down it goes. No banging with wood here. why would u want to drain the fluid without droping the pan, (drian plug), cause how can u change the filter? I was thinking the shift kit was all one piece. U just drop the old valvebody and pop in the new one, darn all the extra work. What do u think the difference is with shift kit and drive gear mod. Besides huge. Compare to 5 speed.
