I remember this thread, but I don't remember what, if anything, that I
replied with.
I did a LOT of research prior to starting Christine's modifications.
Best I can tell is that a Ram transmission will not work with a Dakota
set up. Why that is, i do not know. But every single interchange and
look up I came across, salvage yards, etc.. said they were not
interchangeable. Something about the bellhousings.
Having said this... you will have to make sure you get a compatible
drive drain, to assure you have stuff that will work. I.E. an engine
and trans both from a Dkaota, or both from a Ram/Van/Durango/Jeep ZJ .. etc.
As for the 46RH, that transmission has very few electrical connectors.
You will have a three wire connector for the neutral safety/backup lamp
switch, one connector for both (together) the overdrive and lock up
solenoids, and you should have one for a speed sensor on a 2wd tranny...
on 4x4's the speed sensor is in the transfercase. The speed sensor can
be ignored if you plan to use a carbed set up, or a stand alone
megasquirt/FI set up. The sensor can be left in place and still will
drive a mechanical speedo. (however depending on the application, some
may not use cables for the speedos in which case you should be able
remove the sensor, or swap out an older one that uses a cable (like my
89 does) thats a minor issue either way.
Aside from that, the 46RH does not need any special treatment to put in
a situation like that. Then again you could always go with the old
faithful, 727 torqueflite and forget newer trannys all together.
46RH's were found in 94 and 95, 318 Daks, and in 94 Rams.
Also keep in mind differences between the externally balanced 360 V8 and
internally balanced 318s. The flexplates are different.
