At the Gnats last week our car developed a nasty habit of not upshifting under full throttle. The car runs and drives fine under all other conditions, however. The diagnosis we received was that our governor tossed the spring, so we procured a replacement (with a pinned spring) from SE Turbo and plan to install it this weekend. Does anyone have any advice or info on this task? We've installed a number of valve body kits and such, so we're a little familiar with what a TH200R4 looks like behind the trans pan. Are any gaskets (besides the pan gasket) required? Any special tools? Thanks!
