No, they lose more power through the tranny than the manuals. Also, the shifts aren't as firm since they're controlled by hydraulic pressure. Nothing a shift kit can't fix, though.

 

i think its partally the gear ratios first is only a 2.84:1 and mostally that you cant launch as well because the torque converter has physical slipping rpm limitations before you will just spin the tires trying to powerbrake.

 

i firmed up my shifts with my tuner, and it was a huge difference, not to mention my shift points i changed...so when i get gears, am i gonna be f*cked by my rmps since i have less gears? or is my mph gonna change at those rpm's?

 

it will only change speed at the given rpm your shiftpoints will all be the same.

 

now i am really worries with only three gears, what can i expect to see at say 2500rpms in third gear?

 

46.6 mph in 3rd with a 4r70w at 2500 rpm

 

with what gears?

 

4.10's

If you use the OD you can go 70 at 2500 rpm with those same gears.

 

i don't understand, now my rpm's are at 2200 in third gear at 50mph, so my mph will actually drop?

 

With 4.10's and not correct, your speedo will still say you are going 50 at 2200 rpm. But you will actually be going about 41 mph.

those numbers are assuming you are not using OD
