Has anyone ever encountered a p2821 trouble code for a 2013 Honda Civic? No check lights are on the dash or flashing D, only a message on the imid to check transmission. This causes the car to take a while to change from 2nd to 3rd. Once I switch off then on the car the car changes soomthly as it should but ones the message comes back the the car starts behaving badly.
I already changed the fluid and linear shift solenoid A without any luck.

Would really appreciate any insight into the problem.

thankfully its not a cvt...

start with 3 drain and fills and a bottle of lubeguard platinum, 1oz for every quart of total the transmission fluid capacity.

this is cheap to do...
