There is no JMOD "kit" per-se.
max at fivestar ford sells everything you need. I believe this Dan newman guy does too, although i have never dealt with him. I just see his name everywhere.
basically, 1-2 accum-piston, 1-2 upper spring, 1-2 lower spring(if so desired), 2-3 accum-piston, 2-3 spring(if so desired) 2 separator plate gasgets, new pan(deeper 96+) if needed, new filter, 1 case(plus 2 extra qts incase you spill) Mercon V.
then, get a tranny cooler...with that kind of mileage, it might be too late though.
I called max at fivestarford for my JMOD kit...he head everything in stock, and it cost me $112 including freight for all the shift accum, tranny pan, new pan gasget9didnt know i didnt need one), and filter.
