I have a auto p30 ecu and i'm throwing the code 19 which is Automatic transmission lockup control valve. My car is an automatic as well. But when i'm driving it doest let me go past 7k rpms in 1st and 2nd gear but when it hits 3 gear it revs up to 8k rpms. My question is, if i convert my auto ECU to a manual would the code go away? And is there going to be issues if i do this converstion?
