Most Mazdas 5-speed trannies are nothing but 4-speeds with an OD. I know of many MX-6s that have blew their near bulletproof F2Ts in 5th treating it as an extra gear going 130+mph. As long as your not at WOT for too long, I wouldnt worry too much about it. I only go into 5th when I'm at a steady speed on the highway or otherwise I'm in 4th.
Saw your P5 the other day, s*** looks clean! I want it!
