The original transmission and transfer case choices were the
Dodge CTD TF727 and NP205 that I pulled out of the 91
Dodge CTD donor truck. However, I came across a good
Dodge CTD 46rh (A518) over drive transmission core that had
good forward gears. But, no reverse gear. I dropped it off with
a Dodge muscle car buddy that rebuilt transmissions on the
side. He did a super job on the rebuild. I later found a good
used NP241 transfer case that would bolt to the 46rh. I
eventually had to create a hybrid NP205/NP208 shifter with
NP241 linkage to make it all work right. It turned out better
Pics below are of the 46rh bolted to the 4bt prior to
installation. I used the 89 thru 93 Dodge CTD transmission
adapter and flexplate and bolted on a new 89 thru 93 starter.
