E351 Transmission Swap

The E153 transmission from the MR2 Turbo is strong, but that strength is also it's greatest weakness. Large, heavy gears that generate a lot of heat, waste power, tear up synchros, and don't shift very nicely (especially the early boxes like mine). Plus they have become difficult to find on the used market, and rebuild parts are no longer available for the early years. There has to be another option!
