Yup, it will all bolt up together.

Your biggest hoop is to get in contact with someone who makes that transmission computer. They may want to know exact transmission numbers because the 722.6 came in many variants and different valve bodies, the number on the side would say 722.6XX (I can tell you exact numbers off a C36 trans, I have one around)

Overall, the 722.6 is a good transmission, when it came out in 97' it had flaws that overtime got fixed with updated parts. Buying a used one maybe a tough call because if it wasn't rebuilt, it may soon fail.

There is reputable rebuilder here in NorCal, search Peter Schmidt transmissions.

If and when you do get closer, let me know if you need any parts, as I have basically all of the automatic parts left around from a conversion (shifter, wire harness, factory tcu., flex plate ect ect. I also have a running 722.6 around but has slippage in 3rd under WOT, so it's a good core!
