I'm planning on buying a 13-14 gt and making it my main weekend cruise/speed boi. I know that the manual trans can be delicate and since I'm gonna buy a used gt with low miles I know manuals will be beat on more than autos. But I wanted to know what transmission is generally better for adding power reliably. Things that I'm considering is reliability, the cost to upgrade, how much power can it safely take before needing an upgrade, and the cost of repair if anything happens. I'm not considering the fun factor cuz I know the manuals are more fun. Now, if the s197 had the manual transmission of the s550 there would be no debate. Sadly, the only way for that to happen is swapping transmissions.
