Help ..904 has died 4 times !

it is likely that AAMCO has no idea what to do with an early mopar trans 904 727 or otherwise.......unless they have a really old guy OR a super gear head working there. YOU need to find a guy that KNOWS mopars...and get your car the hell away from those AAMCO guys ...that is just asking for trouble...tow it tug it push it drag it the hell out of there...my guess is the oldest person in there is maybe 20...your car is older than him LOL

there are plenty of people on here who can tell you the correct config for what you runnin...and likely WHERE to get your trans done right....

sounds like you have tried to let them direct you and then BUY them into a success...but they have no idea what to tell you to buy!!! so before you purchase the entire JEGS or SUMMIT catalogue trying to bail their dumbasses out...jerk it out and talk to the pro's here...it may take a lil longer but you will not be told ...buy this NO buy that NO buy this...etc etc

good luck someone will jump in
