Outer Limits 4x4 Board

I crrently have a 1995 v8 3.9 disco with a manual gear box. Can I fit an auto into it? and if so what do i need to do and roughly how much would it cost? cheers guys

tranny flex plate and spacers torque converter shifter oil lines and cooler
engine crane makes the job easier
not a super hard job but time consuming should be able to do it for under 1k price of gearbox is the exxy bit

transfer jack shaft, kick down cable and a bit of wiring.
