i have a 1999 p71 and the transmission is slipping. i was wondering if you get the steel driveshaft and a regular crown vic transmission, is it a direct bolt on, ie:all the connectors and cables just bolt and clip right in? or does it have to have a p71 trans put back in. also is the regular 4r70w rebuild kit the same kit i would use to rebuild the clutch packs in this transmission?

From what I read, the trans are the same. Just computer programed. Unless someone had one rebuilt by a custom trans shop for racing. Usually you just replace one trans with the newer one and replug and GO.
