trannie????
I have small rear tires (25") so I had to go with the 600 with the 2.87 first gear. Now I can do 30 mph in first gear. It would have been cheaper to buy tires and rims. 
What size tires do you have and rear end ratio? You need to consider first gear speed and four/fifth gear cruising speed/rpm. Look at everything and pick the best compromise for you.
Here is a car math site to help.
