Hello, My name is\*\*\*\*\*'m the Technician that will be assisting you today.
I co-own a Restoration/Advanced troubleshooting shop. So My hours on here vary day to day.
**If I respond to your question that means I will be online for at least 30 minutes. If you respond after that time period, I will see your message and review it. But will not respond until I back get online.**
I do not work for Just Answer, They have just allowed me to use their platform to help customers like yourself.
**You may receive a automatic call request, which is a good option if you don't like texting. But I will almost never have the time to place a call. If I'm assisting you and we find a call is the best route. I will call you then.**
**Also under no circumstance do you post personal information other than your first name. If personal information is required (like your phone number) Just Answer has a secured way to exchange information.**
Its a pleasure to get to assist you. Whom do I have the honor to be speaking with.
Hello, Which engine do you have? Thanks

Thanks one moment.
Do you have any other codes?
Normally the incorrect ratio codes means something internal to the transmission has failed. Would need to do some test to verify if you do not have any other codes.
Do you have a pressure gauge?

Okay, So we do need to check the transmission line pressure to see what's going on.
The p203f is a separate issue.
