Noise--Sounds like a chicken is trapped in my diff
Tranny--HORRIBLE GRINDING, AND SHUDDER goin into 3rd at any moment Freeway or Street..And now have to get another tranny..Also the guy didn't put a Tranny Cooler with it..So go figure what happenes

I vote 3.73 since it is an auto car. The 4.10s in my car are wicked quiet (so quiet in fact, I can't even hear them they are as quiet as stock), and have been for 40k miles. Just use GM OE 4.10 gears if you are in a 10bolt and I bet they will setup perfect using the stock shims. Same goes for the 3.73's, get GM OE gears, not Italian made Motives, or Richmond etc. The GM OE gears are made by a division of Motive, and are made in the US. They normally come under a generic name. I'm sure one of our sponsors sells them, or you could google GM OE 4.10 and see what happens, or PM me for where to get them.

My mods are 3.73's, LTS, lid, and tune..
I got like 18mpg mixed with a heavy foot pre mods.. and now I'm getting about the same thing 17/18 so nothing too drastic.. but it makes a HUGE difference in the fun factor

exactly! m6's need at least 4:10s to even feel a difference, anything less isnt worth the money. cruisin on the interstate at like 2400 rpms at 80 is great, but having that snappy first gear makes it even better
I've never felt how snappy it is

Putting gears in a 10 bolt is $500 that you will wish you had when you go to buy a 9"
