gm also had an optional manual trans known as the zf6
A few years ago I was looking for a extended cab duramax to tow my 5th wheel because with the addition of my second child the family of 4 could no longer fit in the '77 K20.
Found that the duramax trucks were too expensive and ended up getting a great deal on a 2003 Silverado with the 8.1L and the ZF6. The manual trans lets more power to the ground and gives better gas mileage. I get 14-16 on the highway empty and 11-12 towing. I've never wished once I had the auto instead.
And with all the $$$ I saved getting a gas truck instead of a diesel I had enough left over to buy a 2000 VW Golf TDI. I use that to drive to and from work and get 42-52 mpg.
