4R75E J Mod equivalent???
Hey all,
I beefed up the 4R70W I'm putting in my 63 Fairlane with a 4.6DOHC and one of the mods was called the J mod. It's where I had to drill some holes in the VB separator plate for better passage, along with different accumulator springs. It basically firmed and quickened the shifts and helped parts survive better.
Is there anything like this for the 4R75E in my 07 F150? I'd like the trans to shift into gear when I put it in gear and not have to wait a few seconds for it to engage.
Anything out there for these transmissions?
Thanks
Dave

You can do basically the same mods to the transmission you have. Feel free to PM me for info.

I got a link from someone on another forum and the site they sent me to had a VB from a 70W and it said was for all 70 and 75's from 2000 up. That confirmed it with the picture that I can do so. PM on the way! Thanks.
