200-4R Behind a 340 and Reid Bellhousing Build

Sounds like you've had some bad luck with some mopar transmission rebuilders. There are a lot more chevy rebuilders out there than mopar; that's for sure. I don't even rebuild the 700 or 2004 anymore because everybody and their brother are undercutting each other. I'm no purist, but I am cost-conscious and it would be difficult for me to invest 6k in a trans but that's because I can put together one myself to handle 1,000 hp for less than a grand. Chrysler was the only company to retain their own overdrive when diesels starting making gobs of torque; Chevy and Ford opted for the allison; knowing their stock offerings were inadequate. Chevy's th400 based overdrive might be a contender but it's electronic; unlike the 90-95 mopar od.
