((You ask like you think I'm stupid or something.)
Every time I say something anywhere about ditching a 904 I get treated like shyt on any forum I've brought it up on.
I have a factory equipped 727 in my /6 truck and everyone and their brother has been trying to convince me to pull it and put a 904 in. That won't be happening. I've never put a 904 in where a 727 was. But I've made the swap the other way more than I can remember. Pull a 904 in favor of a 727.
I have had zero luck with 904s, even without driving like I was in a "race", they have not held up for me. They've basically been junk. I hear of people beating their cars more than never did and apparently not having trans trouble. I've blown more nasty 904s than I have 727s. Either they have a higher tolerance for trans trouble than me. Though I have never "built one up" from stock before. Maybe everyone else has "beefed up" 904s vs my stockers?
I've never owned any brand besides a Mopar in my years of driving but I've had lots of problems with 904s.
