Shawnlee, for lack of a more gentle term, your wrong. The AOD is a Tv cable controlled transmission. the c-series is vacuum modulated. If you have the Great Fun of bolting one of these creatures in sometime, you will find that there are no Vacuum mounts on it whatsoever. Also, the AOD is not by any means a simple or industrial transmission. At around 190 parts, this transmission has a history of being vulnerable to excessive torque and heat. However, tailshaft changes are easy on these transmissions as it has a 6 inch independant housing on the rear.
