I have 2 amc automatic transmissions, one is a 727 the other is a 999, both are for the same vehicle. Well both are having the typical drain back problems amongst other minor issues. The 727 torque converter was buzzing from the time I got it back from the overhaul shop. I need to get one of these operational and back in the vehicle. Who is someone who can either get me a sonnax valve body or modify mine to fix all of the normal issues and who can I get a good heavy duty torque converter from? Thanks
