What is your question?
Car was driving fine just out of nowhere heard as if a belt was whining stopped to check it out couldn’t see much so decided to take car home. On the way home transmission started slipping when changing gears, wouldn’t accelerate so had to pull over. I couldn’t visibly see any leaks from under car or near engine area.
Car was off for 15 minutes and started up fine shifted in to gears normally then after a mile when I came to complete stops heard whining noise and same thing happened wouldn’t change gears or it would slip and barley go.
Basically after I turn it off and let it cool down it works fine but after a mile or so problem starts.
All those codes popped up so hoping someone can guide me before I start blowing money I do not have.
What makes this problem better or worse?
Vehicle seems to reset after cool off but once driving for a little problems starts up

Hi, this is Bo, an auto expert on RepairPal's Car Genius team!
Your Journey's transmission is throwing quite a tantrum with those codes. It sounds like a fluid pressure issue is causing most of your headaches. Low or dirty transmission fluid can often be the root of such problems. Given the whining noise and slipping gears, it’s likely your fluid isn’t doing its job. When the car cools down and things reset, it hints at a heat-related issue, possibly with the transmission fluid pressure sensor or even the torque converter.
A thorough check of your transmission fluid level and condition is a good start. If the fluid looks good, the pressure sensor might need a closer look. If those don’t solve it, internal transmission components could be at fault. It’s a bit like a bad relay race – one part fails, and the whole system goes down.
