2000 5.9L ecu/nv3500
Hello fellow SW WA member 
Anyways, you best bet I believe would be a SCT tuner with custom tunes to "remove" the automatic transmission.
Any NV3500 from a 5.2 or 3.9 will bolt to a 5.9. Be sure to use a 5.9 flywheel, the 5.2 is internally balanced, the 5.9 is externally balanced.
