So, is Dodge's "fix" for 5th gear on the NVG 4500 for, let us say, the 2002 Dodge Ram diesel just out of the factory "not very good"? In other words, if someone were to buy a 2002 with 5-speed, that person would need to somewhat promptly find an after-market fix for fifth gear? Thanx. Jim (Sorry for my confusion. )
