4bt install... Need advice on auto trans choice.

I have a 77 that I bought specifically to use with my 4bt. The only issue I'm having at the moment is choosing which auto trans to go with. The wheelbase really limits choices quickly. I have a np205 currently in it behind the c4. I also have the turbo 400 from the Grumman. Then I also have a 47re. They are all longer than the c4. What trans have others used with success behind their 4bt. I'm really excited to play with this little motor. I was pretty serious in the diesel racing community for years. This is one of the more rare 4bt's with the Bosch inline pump.

Has anyone successfully ran a 4bt/np205/turbo 400 combo in an early bronco?

All help is appreciated.

Post #81 if you want to stay with c4 or first gen dodge diesel with 727 but you need an adapter to 205. The 727 is nonlockup so the motor adapter is 1" thinner then for a 47rh/re. That helps. I have zero experience w/ turbo400.

I'm still trying to see if others have made an overdrive auto trans work in one. I want to get started, but need a definite gameplan first.

When I was collecting information for my swap I copied from somewhere
"47RH from Dodge and get an NP241. Just go to a yard and snag everything from behind the block of a 6Bt with an auto"

I am not sure who posted this or if it even fits. I went with a manual so I never looked any further. Good luck

The 47's with transfer case are about 11" longer than the c4/205 I currently have. I just want to make a good choice to begin with.
