[QUOTE="elrodalexander73, post: 1286262, member: 16217"] 5-600hp... Billet input shaft Billet overdrive planetary Billet Fwd Drum (holds 6 frictions and 6 steels instead of stock 4/4) "NEW" hardened input shell (a must) John Wood sells a cryoed intermediate shaft that "will work" Use either upgraded rabestos or HD borg warner clutches. Kolene steels help. Transgo tugger and buy a second shift tailoring plate, learned this the hard way.. If it's a 4R100 it's already got a 6 pinion Low reverse planetary, your coast clutch assembly needs a reallll groove machined to hold the snap ring in place. The backing plates can be bought through a few places to add extra clutches to the direct pack and intermediate. Check your 6 pinion fwd/direct planetary very closely. There are a few ways to set the low reverse clutch pack up.. I've built several like this and they are still under plow trucks... BTW John Wood is thee absolute best option for anyone over 600hp, he puts plenty of real billet in his trans, not gonna get into other builders about this. And yes you can get him on the phone. Just have to be persistent. [/QUOTE]
