So I was driving the other day..all was normal and red triangle came on and transmission acted like I was I was in neutral...pulled over..transmission started working normally so I drove home..not far. Don't have access to techstream. Came out a few hours later..auxiliary battery has less than 2 volts.. Can a bad 12v battery cause thus and if so please explain?
Just like the thread you started back in April of this year, you need to get access to a capable scan tool to read the trouble codes that are triggering the red triangle. Until that is done, you will not know how to fix the problem with the car.
