I am in the process of doing the J mod on the 99 Mustang trans I just bought for my 97 Tbird. I successfully did the J mod on my old trans 2yrs ago, but I have questions about the differences with the newer trans.
I have spent hours reading Js thesis and every post I could find - now my head is spinning.
Can someone just tell me if the 99 Mustang trans comes with the mechanical diode?? I just need to know if I should slot the #6 hole or just leave it at 0.125".
And just to confirm - I should otherwise just follow the drill sizes based on the year of my car?? (holes #1-#11).
