2002
A new transmission was introduced, working without a clutch, the optional sequential manual gearbox had no conventional “H” pattern shift lever. Gears are changed by moving a floor lever forward to upshift, or back to downshift. Or, the driver could use an optional pair of steering-wheel buttons to accomplish the same task. No automatic-shifting capability was provided, and no automatic transmission was available for the MR2 Spyder.
