04 Auto tranny Jmod

mustangmike! · October 18th, 2011, 03:24 PM

Decided to post this hear since more GT people tend to do this.

Been looking up articles on the Jmod. Most info is for the older 94-97

I understand their are differences in the mod for 99+ models

"In 99+ transmissions the jmod is removing the 1-2 and 2-3 accumulator springs, and drilling out a few holes on the seperator plate."

This "update" seems to be what im looking for as far as a guide as to what I need to do.
