It's 2:26am Do you know why my car wont start?

I'm talking when using the nag1 trans. You need wheel speed sensors to properly operate the trans. The older ram pcm's 03-05 rely alot less on speed sensors. So you have less headaches with the pcm going into limp mode. I don't know if the ram pcm will contol the nag1 but it might with some work. If your looking at a non compter controlled trans and you just turn the trans options off then there is not much to worry about. Another thing to think about is in 08 all cars/trucks came with traction control. And could pose another problem there. Research will be key. But an early pcm would be the best option
