Wow, Sorry to hear that, I met Mike 20 some year ago at Brainerd Mn. ended up pitting next to him I was going goofy looking at his cuda he was under it I said trouble , yea transmission , I have a spare but this is my best one, I said I know mopar transmissions I'll look at it after you get it out, I went for a walk and came back an he had it completely torn apart all over the trailer floor , he said sure hope you can put this back together!! I did and it ended up being a valve body problem and we took the one out of his spare trans and every thing work fine, next race I seen him at he gave me a bunch of pic's like the one in the first post. great guy, very smart.
rest in peace man.
