The dealer told me that I have 3.73 But According to what I've read on hear that the 08's with the 6spd manual have 3.42 does that include the dually's
My rpms at 55 are just barely at 1500 at 70 mph I'am running at 1900 that seems like 3.42's to me cause my 03 with the 6spd manual 3.73 gears at 70 was at 2100 rpms altho I know that this a G56 not a NV5600 speaking of the NV5600 that tranny had a clutch that felt a lot stronger then this one any input would be appreciated:beer

I think you have the 3.73s. The last 2 gears in the Auto are Overdrive gears where only 6th on the manual is an Overdrive gear hence the difference in RPMs.

sound like 3.73s to me also

He has a 6 speed manual, guys. Not the auto.

I have 3.73 and I run 2100 rpm at 70 mph. I would have to say you have 3.42 gears.

My mistake, i thought he had the Auto, dont know why.............
