Thanks very much for responding to my post. Yes, I've done a little fact checking myself and as you stated the cost of an overdrive transmission whether it's the 700 or the 200 is more than I want to spend. I understand there's other issues with the kickdown adjustments and or install. Anyway I've begun the process of putting it in my GTO. I've taken the driveshaft off and I've taken the tail housing off the turbo 400. One thing that those of you that are considering this may look out for, there's no gasket for the New tail shaft housing but your vendors. They have engineered an O ring seal for that purpose. So far, it's been somewhat of a struggle for me to knock out or in large , if you will, the tunnel for the gear vendors to properly fit the A body. Here is a video of what I've accomplished so far. It's a video I made for my friend Bob.
