I've got a '99 4.3 swapped into a Jeep, I'm currently running an NV3500 but the case is cracked and I'm thinking about going to a 700r4. Does anyone know what I need to make it work?

 

You'll need a flexplate and some way to hook up the TV cable. You'll want to add a transmission cooler. Also the correct adapter for your transfer case. I have no idea if the driveshafts will end up the right length or not. Other than that, I think it's pretty straightforward.

 

That's basically what I figured, my main concern is getting the TV cable to work. I'm hoping someone on here has done this before and can shed some light on it.

 

What type fuel induction are you using? Carb, TBI, injectors. Will determine what set up you need for the correct geometry.
