Newbie question here. Does anyone know of or can recommend somewhere to buy a bulit 4r70w tranmission for our mark 8's. I've been researching the posts on here and I see the J-mod seems to be choice for the marks, but with a 125000 on my orginal trans I'm looking just to do a swap rather then a slight mod on worn out parts. Any input I could get from you guys would be appreciated.
I've used Lonnie for the tuning on both my Thunderbird and Mark VIII. Although I don't have experience with his transmissions, I'd believe he does good work.

Darrin or Dirtydog on TCCoA and Lonnie @ BOC.

I've also seen Darrin and Dirtydog's work and would definitely trust them as well.

I got mine rebuilt with a B+M rebuild kit and a B+M shift kit. It shifts hard eno to chirp the tires going into 2nd and 3rd, kinda ridiculous tho
