I recently had my local friendly Dealer perform the RDU flush over a month ago and most recently had the trans fluid flush performed,in both cases they needed to be flushed twice at roughly 32-33k on her with the trans fluid flush covered under warranty and the RDU was performed as a courtesy,today received an update in regards to having the PTU performed on my PP SHO which is somewhat a pita,my dealer quoted me 400.00 which will also take roughly 3hrs to perform,but as a (courtesy)for such a wonderful loyal customer they will charge me 150.00 if i bring my own fluid,have an appt at the end of the month and will update you on any findings or possibly some pics to follow,hope this helps anyone considering this procedure.
