Any help would appreciate.

Answer 1

I dont think the code is related to replacing the gearbox 

p0011 is most likely caused by dirty oil. 

Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code.
