Re: Upgrading an AOD?
Yep, Broader performance has an excellent AOD for street and strip for $1600. It is made to stand up to 400 - 450 HP. They also sell a C4 to handle the same HP for $800. AODs are expensive transmissions because they require so much work to take the HP. Basically anything after 1985 before 1993 has to have hard parts changed out to make it work with that much HP. Even if you start with a 1993 AOD you have to modify or replace the hardened shafts, lubrication and cooling ports in them. There are about 27 mods that are made to the valve body and some machine work to the pump, stator and case.
This is not anything like the C4. You also need special tooling to set end-play, replace bushings and check clearance for the intermediate clutch. Unless you are going to build more than one it just isn't worth the cost of tooling for the average guy doing a rebuild in his garage.
