Zitat:this is from a dealer posting. I have some scant info that it is indeed correct. Apparently the 3LT-Lt option code is the old 1SB plus the Z51 package and navagation.
the big deal to me is MXO...apparently now 6 speed. I see no G90 option for the 3.15 axle. For what it is worth I captured the following...

Zitat:I found some specs on the STS-V Hydra-Matic 6L80. It has a listed 430 lb-ft of torque capacity versus the current C6 4L65E of 380. The six speed in the caddy has a 258 mm torque converter versus 300 mm in the 4L65E. The fact that it has a torque converter says that GM went cheap versus the Audi twin countershaft model. The gear ratios of the 6 speed versus the (4 speed) are listed below. The lower gear ratio for the 6 speed first gear suggest to me that the G90 axle (3.15) probably won't be offered for 2006, which is consistent with the option list I published above.

1st gear 4.02 (3.06)
2nd gear 2.36 (1.63)
3rd gear 1.53 (1.00)
4th gear 1.15 (0.7)
5th gear 0.85 --
6th gear 0.67 --
reverse 3.06 (2.29)

Zitat:this is from a GM Powertrain posting...

Zitat:I was about to order my C6 Monday but read about the new 6spped auto replacing the 4 spd. Any idea how soon this new tranny will become available?

Zitat:Dealers can not order 2006 Corvettes until late June. The tranny will only be in the 2006 model year and that production doesn't start till September 9th.
