Error code p220a?
Mechanic pulled the codes to reveal p220a "the speed comparison of Y3/6n2 to Y3/6n3 is implausible".
I told the mechanic about the conductor plate needing replacement, but he dismissed that saying the car needs a new transmission. Then he checked the fluid and there is no presence of damage by coolant in the transmission. He says it is likely the "valve body", which will run me about 1000 dollars at the stealership. Does anyone know the part number of this? What is the purpose for the valve body?
I would appreciate some advice and will keep you posted for anyone else experiencing this issue, thanks!

it was in limp mode so only $2700 for the car.
Replaced the conductor plate and filter and connector plug and gasket. New fluid. Cleared codes. Drove great 2 weeks. Then i saw a little trans fluid in the driveway.
Ordered another kit as i inspected the connector plug was Leaking and it ran along the pan making it seem to be the gasket. 2nd replacement done but this time i for some reason unplugged the battery. Now it didn't clear the codes and engine cranks up and runs for only a second or two. What did i do wrong?? 😕🙄
