i have a t-18 already... granny first as well.. its in my CJ with an adapter to the dana 300.. so if i swap in a 4bt i only need the engine, adapter and bellhousing, not the trans.. thanks thoughI got an NP435 that I need to get rid of. It would bolt right in place of a T-19 plus, has a granny gear.
Chances are you will buy an engine like I bought mine: with the adapter, bell and trans all attached. I just unbolted the NP435 that came with the engine and bolted it right up to the NP435 already in the truck. It made for an easy swap.so if i swap in a 4bt i only need the engine, adapter and bellhousing, not the trans.
