Jmodding 2001 4r70w

I cant seem to find any info regarding the Jmod on a 2001 crown vic transmission. There was nothing to doing it the first time around on my '94 transmission.

Is the top 1-2 spring in this '01 tranny the same as the top 1-2 used for the jmod? I need to know if I should order that spring, or roll with the one I have.

Where do I find out what holes to drill and what size? Just drill it like a '97 with <300hp as outlined in the man's thesis? Does this still hold even though it has the '99+ valve body?


These questions may sound dumb, but I just want this to go as smooth as possible. Thanks in advance.

Best bet is to read through pages 13 and 14 of the OD 101 article, it will show you what holes to drill what size.
