Finally pulled the 200-4R

It's a tough transmission. I know two people with Grand Nationals putting out over 1000 hp and they have no problems. I have seen inside it and other than the 8 clutch pack as opposed to 6 it is like any other transmission. It has a few different springs and a few check valves are removed, It has a bigger servo and a special apply valve in the pump to create flow with the non lock up converter. I didn't build it, and I am not a transmission guy by any means, but I am very mechanical and I have been around builders before. This is a transmission of choice for many because of it's size, gearing, overdrive and reliability. If you beat up any transmission like I do, you have to expect this kind of thing to happen. I'm not happy, but I know I brought it upon myself.
