Getting to the final steps to complete my Gen III Hemi and NAG1 transmission swap in my 1968 Charger.
Unfortunately I haven't quite sorted out the speed signals to the NAG1 and it is causing Limp Mode and not shifting consistently.
Hope to get this sorted soon.
Otherwise the car starts, runs, and drives really good.

Link to my latest video -

Could have a bad plastic separator plate in that NAG causing an input speed sensor problem..Idk for sure whiteout seeing it but that is a very common problem. Replace with a Dorman part versus the oem as it’s a reboxed oem part in a dorman box if that’s the case.
Nice work your almost done keep us posted.
You guys who know these new engines and computer systems amaze me. I am in awe of what you know. I packed up my tools and quit the business when GM sent me to Tarrytown to learn their 'new' C3 system. Nice Charger.
