Ok well I I thought I had a NSBU issue repalced (with one from allison) This fixed the issue for a couple weeks problem came back so i though switch went bad swapped out for another switch. Did NOT fix problem i have also found it will not go into tow/haul or turn off overdrive in drive I have to put trans into 3rd and when I restart the truck thats when it acts up sometimes I have a check engine light sometimes not hooked a snap on solus and it wouldnt even read my truck Im guessing it didnt have the software so I cant even tell what the CEL means its so randim now any thoughts? Oh I changed fuel filter 2 weeks ago

What exactly is the issue??

Just that the T/H and 5th gear lockout do not work?

It would be best if you could go to an auto parts store or somewhere and get the codes pulled.

No the issue is that on occasion I still get range shift inhibited and some times it wont show the indicator line could it just be a code that needs cleared for the new NSBU to function right
