How much HP/ torque do you plan to apply?  :-X
The 5.4 swap has been called a bad idea, and considered an underpowered considerable waste of time, since 2007.

Nice to see that most donít think that anymore.

These trannys are all pretty tough.... you will get a better rebuild with newer plates and  bands due to upgraded friction material. my rebuilt 95 box was faster than the new one (not broken in at over 20K) , but it only lasted about 100K miles. I think removing the wavy and adding a plate or two is about all they need , plus the stronger, newer mechanical diode,  The J-mod isn't all that much of an improvement over a good shift program on a chip, as far as I am concerned,.Problem is too many people wanna make the MN-12 a race car, when it is too heavy , and has that wonderful  IRS which isnt great for drag racing, so set it up conservatively, and enjoy what you have as a street car thats quite fast, heavy , but handles great too! And thats my 2 cents worth!

you could probably leave it stock and get fantastic results, you could also upgrade it to 4r75 spec (i don't recall how to, something involving the changing of clutches). i am also going to be trying something soon on maybe my 3.8 bird to see how well it works. if it does, it will basically be a shift kit with no drilling or valve body modification, and you won't have to remove the valve body. and if all goes well you can turn it on and off. if it works i'm going to call it the "k-mod"
