How much slower is a AOD than a T-5

[Unit 5302]

The torque multiplication from a good converter should make up for most of the hp differential between the T-5 and the AOD, which is about 5%. The other thing to consider is the wide ratio between the AOD and the T-5's gearing.

The C-4 is about 2% worse than the T-5, sitting at about 19% loss. Putting on a lighter converter does make the tranny a little more efficient, but probably only a percent or two. (Talking out of my *** a little there)
