hell no
no auto SS is going to last konger than a manual.
i am changing my tranny this weekend, its a m2s4 (h23a1) tranny that ive been using for its gearing, because i prefer it over the m2a4/m2f4 (h22a/h22a1) tranny's.
it has 231,000 miles on it, it still works but recently the diff carrier bearings are failing and it whines on the highway, very unsafe if the diff were to lockup.
point being, no way an auto lasts longer or holds more TQ than a manual, unless this auto is built 100%.
