Why an auto? probably get better use of the power with a ZF-5

needs to be a diesel C6 (there own bolt pattern)

but it sucks so use the zf5

Tranny will also have a different shift pattern than a gasser. Also, in order to get any millage out of it, you'll need too run about a 2.73 gear and then you'll have no grunt off the line. The c6 was never a good swap in behind the 7.3.

good to know, my boss did change his mind after i told him all this stuff so hes just leaving it as a standard and on monday i have to put the new dually box on, paint the tail gate to match and hopefully start putting the lift in it
