Hello, my name is Tom, I am an ASE certified Master Mechanic with 15 years repair experience repairing vehicles.

Those codes are for internal transmission problems. Input clutch soleniod valve, and direct clutch solenoid valve.

The first thing I like to do when I see these codes is to drain out the old fluid and put new transmission fluid in.

Be sure to fill the transmission with the proper fluid and to the correct level. Incorrect fluid types and levels can cause further problems to your vehicle. You may find that the only problem is in correct fluid, or wrong fluid level causing all of your problems.

Transmissions are very difficult to work on for the novice owner, if you do not have experience rebuilding transmission I do not recommend trying to open it up for repair as you will most likely make things worse.

I will attach some information on the codes you submitted. If there is anything else I can help you with let me know.

Here are possible causes from the service manual. These are in addition to poor quality or low / high fluid possibilities.
