Transmission Rebuilding 101

a good thing to have is some real automatic transmision asembly lube i cant remember the brand i use but its a white plastic container with black and blue text on it, that stuff is lots more slippery than anything else i have tried and makes it lots easier to get all the seals to slip in nicely!
also lots of patience is usefull! (think twise do it once)

i think dose guys runnig 904 internals in 727cases are doing so becuase they want less power loss and as we all know no 904 cases fits bigblocks so those two things maych each other!
corect me if iam wrong but i think AMC used 727 gearboxes with 904 internals, so i gues it could be posible to take those internals and put in a 727mopar bigblock case but this is not guaranteed to work just a thougnt i have been thinking some of..
