Most of the assemblies on diesel's are sold complete, fuel pumps, HCU's ect. For the longest time we could never get any trans rebuild parts for the getrag. I remember ordering a complete trans for a new truck that only had a broken shifter. When and if rebuild kits come available from chrysler, its almost as much as the assemblies. Bert Smith diesel is about the only place I know locallly that has much experience in them. I'm sure there are others, but we don't get a lot of truck work through here, those cummins hold up pretty well. Just cost a bunch to fix.
