Re: Building a performance AOD? How tough are AODs?
Jay, at Broader Performance, is a great place to get parts or a complete transmission - AOD or C4 - at a good price. 500 HP is easy to handle with an AOD as long as there is no nitrous or blower involved.
Some of the confusion in building one comes from the "band swap". You can't put the wider band in the AOD without using the later model drum - the easiest way to get the drum is to get a 4R70W and use the guts from it in your AOD. That way you get the wider drum and the steel drums for the "Power Pack" kit that gives you the ability to use more clutches. You also need to upgrade to the larger servo - "A" or "A+" for OD. An aftermarket valve body is the best way to get a long life out of the AOD. If I wasn't building my own I ould be buying them from Jay. He ships anywhere (I only build locally) in the world.
