OD for PR5?
is their an overdrive for the std tranny? because i red some review of the PR5 and it said that it came with an OD for both the Auto and the STD but when i am going highway speeds the tach says 3500RPM which is too high for 5th to be an overdrive, usually if you have OD the RPM's are @ 2500 going 110KPH

technically, fifth gear is an overdrive gear because it make the engine spin slower than the output from the tranny. which really make no sense to me because then the final gears turn it back up. maybe they do it to save space or something.
now BMW's have no overdrive in thier manual boxes. fifth gear is a straight 1:1 ratio, with all lower gears going down from there. maybe that's why they are at the top of the heap...
