I never weighed them but i would say the auto will be a bit heavier.
With the 4L80 you'll never have to change the clutch

Won't have to worry about the back end (joint's,half shafts R&P etc.) either , just another plus.

That looks really stout!

Just a curiosity question, could a 6L80-E be used? A 6-speed auto Z would be pretty sweet for daily driving.

the gearing in the 6L is crap.. It set up for truck. You would need 3.08-2.70 rear end, then you still have a OD thats out of wack..

You made a extra one, right Pete.

14 K is way high. The conversion should cost no more than doing the same in a C5. Parts are the same cost. What say Pete ?
