[93luxurysnake]

Antbody have a full write up with pix for the jmod on a 98 4r70w?

TCCOA has a tech section with the original 4R70W J-mod articles.

The only problem is that all of these stop at 97 an my trans is a 98

I'm pretty sure the J-mod is the same for the '98 as it is for the '97.

If you're interested, RobertP in Carthage, NC sells ready to install J-mod kits with the seperator plate pre-drilled to your specifications (mild - medium - extreme). I recommend the middle setting.

You can check out his website and contact info at www.robstireandauto.com

He's built many of the fastest Thunderbirds in the Carolinas - including mine - and is THE go to guy for parts or work for Tbirds, Mark VIII's or Mustangs in the Carolina's.

He's on vacation now but should be home today and back to work on Thursday.

I thought that the 98 trans already have SOME of the j-mod already done.... just don't know which ones.

i think the 1 to 2 accumulator was updated as well as they came with mercon v and some other revisions as well

They came with mercon v revised 1-2 an 2-3 accumulator an instead of having a wire harness inside they had a circuit board an a got rid of the one way intermediate bearing to a clutch type I think:thumbsup:

If you have a '98, follow the crownvic writeup. Otherwise, use the writeup on TCCOA.
