I know how frustrating it can be to find answers sometimes. That's why I pay close attention to the facts stated by the original poster. He said he has both 904 and 727s. He also said his transmission mechanic isn't that familiar with building high performance transmissions. He said he wanted advice on building a 904. I promote the 727 and I get clobbered by 904 fans but they can't seem to give this guy any pertinent advice. I guess they don't really know much about the actual inner workings of a hyper 904. If they did, the first thing they would suggest is a five plate direct drum which takes a wider band as well. Then red eagle clutches; all forward thins; six into the direct drum. Kevlar band. Very minimum of endplay measured on a cold case. Anything added to this grocery list would be welcomed by all I'm sure.
