Manual vs Auto(locked)
Manual always has the advantage in terms of parasitic loss, regardless if the auto has a lockup converter or not.
A manual trans is nothing more than a couple of parallel shafts with meshed gears between them. So you have to overcome the friction between the gears and the bearings, nothing more.
Automatics have much heavier rotating internals, and they also have pumping losses due to the front hydraulic pump that the torque converter drives.
So basically an auto will always sap more power than a manual trans by design.

Yes but all things equal and the auto with the right converter and regardless of those numbers on the dyno the auto will be at the end of the track first lol

I don't know if I would say that either , I spend alotta time on the GTO forum and many of those are t56 and while true the trans holds up ok + - those guys are constantly talking about eating clutches and how expensive that gets and we even get a good number of F Body guys buying autos from us who are switching from the T-56 to the auto for that reason since we have no core requirement.
I think what it comes down to really is everyones looking for that indestructible maintenance free part when there dealing with HIGH PERFORMANCE but the reality is there is no such thing. When you start making 500-600-700 and more RWHP wether its drive line, engine whatever your going to have stuff break. Reminds me when I was 16 and i broke my rear a few times at the time I didn't know how to set one up myself and I was whining to the mechanic because it was costing so much and he looked at me and said "You play you pay if you don't wanna pay the go buy a little compact car and drive like you have some sense" He was right of course I didn't do that and over the years i have broken everything from crankshafts-transmissions- clutches-rear ends and even once ripped the rear loose from the unibody on a mustang I had its just all part of the performance game,
I think it all kinda evens out from my observation on cost and maintenance on the auto or the manual.

i disagree also...2 years running 9s with a 60 and havent touched it but ti check fluide every once in a while...6 speed guys consistantly break clutches....trannies....rear ends... have to worry about breaking tires loose on gear changes ect...
If your talking about down shifting while locked at WOT very very bad idea. The impact and stress of upshifts and downshifts with the converter locked will be more than a little extreme you will likely break something for sure

If that was at me that wasent what i ment. I ment hitting the lockup after the shift.
ok well that might be ok if your converter is made for WOT lockup But definatly don't let it
be locked during any shift up or down
