Pasnbyu,

Choose your 5th gear wisely. I screwed up and chose the .64OD with 3:31 gears and about the same size tires you have. 5th is worthless unless I am going 80mph plus. AT 70 I'm at about 1800-1900 rpms. My motor doesn't like it. I end up driving mostly in 4th even on the freeway when I really wanted the 5th.

I did purchase the 600 Tremec and like it very much accept for my 5th gear. One odd thing I have noticed a few times. Sometimes it will pop out of 5th, the few times I am using it, when just cruising down the highway. Not sure why?

Mike
