I was at my dealer yesterday getting the ECU upgrade and ask the service manager his policy on performance upgrades. He replied that if they are TRD parts and they install them, the factory warranty will be honored. He then started rambling off all of the available parts, wheels, body kits, supercharger, 5-speed conversion, etc. When I heard the last two I stoped him. I ask supercharger & 5-speed? He replied that they had just received their emission certification for the super charger and it will be available soon and they are going to offer a 5-speed conversion kit. I told him that I was shocked about the conversion kit and if it does become available it will probably be real pricy $5K range. He agreed. Anyway, this is not my statement, I am just conveying what the service manager said, but the guys really know his stuff about cars and was not speculating.
Take it for what you will, maybe somebody else can confirm the information
