Dunno, I just looked in the Mustang one. Likely is though.Maybe he has. Listed the OEM performance parts and his suspension mods. If not track sessions maybe "spirited" driving on the street? Either way, hammering on a known sketchy transmission might not be the best plan. Hope he gets it fixed and does whatever mods necessary for it to survive his preferred use.
Is the racing disclaimer in the Mustang OM or every Ford OM?
