Don't forget the speedo gear to recalibrate your speedometer after you do the gears.

How much highway driving do you do?

What I noticed about when I went form 2.73 to 3.73 is that 5th pulled like 4th, 4th pulled like 3rd, 3rd pulled like 2nd, 2nd pulled like 1st, and 1st was a whole new animal.

Highway cruising it is a good gear, makes 5th gear more responsive.

It absolutely rules on AOD's. Especially highway driving. You dont have to downshift out of OD to pass anymore, you can just ease into the gas in OD and pass easily.

If you look at the actual tranmission ratios, going from 2.73 to 3.73 in the rear end is almost exactly like downshifting the t-5 from 5th to 4th, or pulling the aod from 4th into 3rd. That'll give you an idea of what your highway revs are gonna be.

Couldn't put it any better. Just drove mine for the 1st time tonight with the 3.73's. She pulls good, had 2.73's before. I'm feeling like I want even lower gears but I think with more motor coming in the future it will be ok.

I've actually never owned a car with 3.73s, but i've got 4.10s, and i can rip the tires loose at will....this may not do much for drag racing without slicks or drag radials, but it ups the cool factor a whole bunch.

playboy - have you done it before? Each set up is different - some folks get lucky and simply put things back together with the factory shims and 'luck' into the proper gear mesh. Done/measured properly, there are a number of special tools/measurements needed (pinion depth, backlash, preload on the pinion bearings). It's a job that's best left to a pro, or to be tackled with you by someone who has the tools and knows what they're doing. I wouldn't try it the first time by myself.
