The expense of an automatic is why I’d still choose a manual. New, used or a rebuild.

Can’t remember why you have an auto. I’ve probably asked and you’ve probably replied.

AFAIK, it’s only the later 6-speed Autos that are trouble-free as to normal power-handling. They’re not cheap and probably require computer control.

The G56 Manual has been used in the CTD since about 2007. The NV5600 in mine is well-liked, but now long out of production. A crapshoot on a core plus parts.

My truck is 3.73-geared. With a junkyard axle swap it could be the current 3.42. That’s one long pair of legs.

With 3.42, stock tire height and the .73 OD, 60-mph is a hair above 1,500-rpm on mine with the 5600. Redline is 2,900. Room to grow.
