I just bought a 04 with a 6.0 and T56. The cruise control works in 5th but not 6th?? Can this be fixed in the puter?

The truck was originally a 4.8 with 5spd truck.

Thanks in advance.

 

What gears does it have? Is the speedo correct? Any DTC's?

 

4.56 gears/ speedo is correct/ no

 

Hmm, I don't know then. Try looking through the T56 swap thread, I know some people have had the same issue. I just finished my swap and have cruise in every gear at any speed. But I'm on the stock gears. Going to 4.56's in a week or two, we'll see if the cruise still works then.

 

Ok, keep me posted.
