can you put a 5r110 in a 99 7.3? and if you can how hard would it be to do an also how hard would it be to build it up to handle 450 hp?:evil

If you really want a 5R110 I think in the end it would cheaper and less of a headache to get the 6.0 and 5R110 out of a donor truck with all the stuff you will need, wiring, PCM, misc, and put in. I also like the way the 5R works behind a good 6.0, they do drive nice.

The problem lies in the simple fact that you not only need an adapter plate but you will also need a PCS controller & to program it. If any of you rode around in a 4r100 truck with a PCS properly setup, you wouldn't feel the need for anything else. They will downshift/upshift/lockup/unlock how ever you want them to whenever you want them to.

The extra gear would be an added bonus. But making it work would be a pain in the ass.

Several have tried. I don't know of anyone who continued using the 5R110 with a PCS after a spell.

sounds like it could be a big pain in the ash but would it be worth it bc i hate the way my truck shifts now and i drove my uncles 6.0 and it shifts like a dream and always pics the perfect gear i think any way

i dont see the point.. lots of 6.0/6.4 guys are trying to goto the 4r100 because the 5r doesnt hold.

5th gear OD in the 5r and 4th gear OD in the 4r are the same final ratio so your rpms at speed will be the same. i think they split 2nd and 3rd gear with a 2.5 gear in the 5r.
