in the trans?....no but the rest of the driveline should include new clutch (twin disk), depending on the miles of the car resurface or buy a new flywheel, one piece DS, driveshaft safety loop, maybe upgrade to a better traction lock like the detroit tru trac (no clutch packs to wear out and no more one wheel spin) and if that breaks a whole new rear diff (more splines etc). The mods are plenty with 600-700 RWHP and supporting mods will be required
