P0505 Nissan -

Question

Hi, I have noticed that when I have my air con running and driving at 60 kmph the rpm raise to 3000/3200rpm at stages, the car feels like it's in neutral. I then have to back off the throttle for the gear to engage. It's very strange. I've just had my transmission serviced and the throttle body clean, hoping this would fix the issue, would it be a sensor??
Thanks in advance

Answer 1

This will not be a sensor, what you have is a slipping transmission, Just by turning on the a/c you apply a load to the engine and the transmission work a little harder just to accelerate.
