Regain power loss from auto trans?
Gears, shift kit and torque converter all help optimize your cars auto trans but do not gain horsepower from this so don't expect that.
FYI manuals also have a power loss through the transmissions
10-15% for manuals
15-20% for auto
Given the same flywheel output, a Auto will be faster from a stop, i.e. Drag Race and thats where it matters.
% of loss will vary between ALL components. Hell if I take out the Tru Trac out of my Moser 12 bolt and slap a Steel Spool I'll most like make back 10 hp. Since its a gigantic weight savings.
The trans with the least loss is a Lenco last time I checked. But is illegal in most class racing.
Myself I wouldn't worry about the loss, good trans with a matched stall convertor for your needs and you'll wonder what all the fuss was about.
