J-mod on a 03 questions

[03TrueBlue]

I want to do the j-mod on my 03 but not sure what I need. I am getting conflicting story's on what needs to be done on the newer auto. Can someone point me in the right direction? Thanks

There's a good article at one of the crown vic forums that is specific to the later 4r70w's. Google it and you should find it. If I find it, I'll post the link. Some guys are reluctant to remove the 1-2 and 2-3 accumulator springs, as described. I took them out and I'm glad I did. Shifts under light throttle are still smooth, but full throttle are awesome. You don't need a tuner to up the pressures.

You can also go to TCCoA.com - Thunderbird & Cougar Club of America and look under Jerry W's transmission articles.
