Finally get the Alex OBD-II scanner. After taking a road test, I found that the TCC is lock-up between 40-50MPH, but it becomes unlock beyond 50MPH. I thought this may cause the P0741 code. But, I really couldn't understand why this happened. How come the TCC becoms unlock beyond 50MPH?
By the way, I couldn't get the ranger sensor output no matter where I put the selector. If the ranger sensor is gone, why the tranny shifts perfectly in local driving and TCC also locks between 40-50MPH. I am really confused now.
