2011 Mitsubishi Outlander Sport CVT – overheating + whirring/jerking after ~20 min driving + coolant loss (getting worse)

I have a 2011 Mitsubishi Outlander Sport (\~220k miles). Service history is unknown, but CVT fluid likely hasn’t been serviced regularly.
I’ve owned it for \~4 months. Issues have been present since I got it, but they are steadily getting worse.

**Symptoms:**
CVT overheating warning comes on after \~20 minutes of driving
Noticeable **whirring noise that gets louder and worse the longer it is driven**
**Jerking/shuddering under load**, especially when warm
No noticeable delay when shifting into gear (engages normally)
Issue is progressively worsening over time
OBD2 scan shows a code related to a torque converter solenoid

**Other issues (possibly unrelated):**
Lost about a full reservoir of coolant over \~4 months (possible slow leak — hose, radiator, etc.)
Light ticking noise from engine, but engine otherwise runs smoothly with no drivability issues

**Question:**
At this mileage and with these symptoms, does this sound more like a valve body/solenoid issue, or is the CVT itself mechanically failing?
Is it worth attempting repair, or is replacement/another vehicle the more realistic option at this point?
