I currently own a Chevy Silverado Duramax HD 4x4, with a 6 speed manual transmission. Yet I am disappointed to discover the new 08 Duramax Diesels that GM is offering, you cannot order one with a manual transmission.

I know there are fans of the Allison transmission out there, but I am a die hard manual transmission guy; all the vehicles I have ever owned had a manual transmission.

If GM does not offer another Duramax Diesel with a manual transmission, I may be owning a Dodge Ram 2500 powered by a Cummins Diesel with a 6 speed manual transmission.

Are there any thoughts as to what is going on at GM that would warrant their offering of the Allison transmission only and not having any manual transmission option available? Inquiring minds want to know.
