Yes I have the rebuild kit and the gasket was included - checked it against the old one and they match perfectly - fits the accumulator ok. I guess I can use it as it came apart, but would the side with both springs under the piston even do anything?? It was shifting correctly before the 4th clutch hub went bad. This is a puzzler...maybe someone replaced it with the wrong unit at some time in the past?? What would be your recommendation? I've spent way too much time and money on this for it to fail right off the bat.
