So really, no has any valid data to support that a manual is better than a Auto. If you buils an auto it will be more expensive but likely hold more HP. If you build a manual it will stil be a little expensive but be a little quickr if the cars are modded the same. HP can always be overcome, I just want to know, If an Auto SS is taken care of perfectly will it last through as many hard driving sessions as a manual tranny?
