My 01 P71 was a slug, I think it had some kind of Highway option or something. 2.73's were in it. I had the 4.30's installed by a proffesional so I am not worried about them wearing out prematurely. What I am worried about is my transmission, however, after about 250 miles my O/D Off light started to blink. I like the acceleration the 4.30's provide, but is it going to tear apart my car? I get a noise around 85mph, but attribute that to brand new gears, hopefully after a week or two that will go away, or else I will be taking it back for service under warranty. Anyhow, I would like to ask for some opinions from the old timers about tall gears in these CV's.
Thanks,
Al...
