I'm not too happy a out it bcoz since I've put it in my gear crunches have increased (well, definitely not gotten better). Seems like AMSOIL (I use their special gear oil series 2000) is good only when really warmed up, before that it's worse than the Mobil 1 for gearboxes I had before.
I have problems with going into 2nd when cold. Lately also I think gearing out is too easy, but that might be the shifter bushings (which are to be installed in the next few days).
