So backstory- Car has had tranny issues since installing blower, and putting a few miles on it (First stalled when put into gear, now it puts a load on the engine and slips 1000RPM when kicking from 4>3, and slams into 2nd). Decided I have 3 options- 1) rebuild current auto. could be cheap- could be expensive. 2) buy a reman'd auto (about 1100), and install it. About 1700 overall. 3) Buy manual sixxer, cannibalize it and swap in the stick. Im looking at option 3- I know that 99-00 is different from 01-04. What differences are the reason that the swap isnt direct? I know its a flywheel difference, but what else?
