i have 115k miles on mine... and i have the SS tranny and its doin fine... although i would rather have a manual, i got my lude for cheap, soo even tho its not a manual, im happy, and i was thinking about gettin the JRSC, but now that yall are sayin it wont be able to withhold the extra power.. then i dont know... but i do know that i dont have the money for a 5spd switch.... if i did... i wouldnt have an Auto... ohh well... life sucks, later.
