Awesome! Love the advanced Adapter add on. Hope to do the same on my 79 some day. Well done!

howdy, i just happened to get my hands on one of these auxiliary transmissions but its not the advance adapters version, it's the original warner gears corporation cast iron unit that came out of a late 60s early 70s ford f350. my trouble is i'd like to put it in my chevy but theres a few things that need to happen to make it work. There is a conversion input shaft for the sm465 that brings the diameter down to 1 1/16 and novak makes the slip fit bearing retainer that allows for the gm bellhousing to adapt to ford transmissions and still use a gm throw out bearing. both ford and chevy 4 speeds have a stick out length of 6.5 inches and i do believe novak also makes the conversion pilot bushing, so getting the input shaft on the sm465 to link to the torque splitter shouldn't really be an issue. my issue is bolting everything together. If i use an adapter plate, depending on thickness of the material used, do i need to worry about the input shaft stick out length? The front and rear face of the torque splitter measures 10.5 inches. Instead of using adapters, would it be better to drill and tap the new holes on the torque splitter on both front and rear sides to accommodate the gm bellhousing and sm465? Looking at it and if my measurements are proper the bolt holes should stay on the ears sticking out on the sides on the ranger but one of the top bolt holes is close enough the bevel out to match the gm bolt holes. Do you think this will jeopardize the integrity of the casing if i went with the route of drilling and tapping new holes?

Hey guys if you want to fab your own O/D unit that is just as strong if not stronger than the Ranger III O/D (thats no longer in production) then i suggest getting 3rd and 4th from a dodge NV4500 variant transmission, rotate it 180 degrees, weld up some 2 gauge plates first or have a cnc shop fab the enclosure and you get a 1:1-->0.71:1 o/d unit.

6.68:1 (first)
4.74:1 (first over)
3.34:1 (2nd)
2.37:1 (2nd over)
1.74:1 (3rd)
1.23:1 (3rd over)
1:1 (4th)
0.71: (4th over)

(Note, simulated results may vary from transmission to transmission. As these results represent a near 600-650 rpm drop. i.e., going to o/d while at 2000rpm, it will drop to 1400-1350rpm. A lil steep but at most youd most likely get down to 1400rpm from 2000rpm.)
