Hi everyone

A bit of a long post - apologies

I'm having some issues and was hoping you all can help? I'm not too experienced with cars unfortunately

I bought my car in 2018 new, it has 62k on it. I've been maintaining it per the maintenance minders and the car has treated me so well. It's out of warranty as well.

2 weeks ago it started having some issues. It would sporadically rev up to 4,000RPM when I'm at 25MPH and not go any faster. I guess this might be slippage?
When this does happen, it felt like it would decelerate a lot more when I took my foot off the accelerator too. Doesn't happen for every drive nor every part of a drive.

Then I started getting a bunch of warning lights, EPS, VSA, AWD, TPMS, ABS, Brake system. Car was driving fine either way.

Took it to O'Reilly and the OBD reading gave me these 2:
P2720 A/T Clutch Pressure Control Solenoid Valve D Low Input / Pressure Control Solenoid D Control Circuit Low
C003A-3A Wheel Speed Sensor (Right Rear) Signal Failure

I took it to a transmission shop and they suggested replacing my transmission entirely but suggested I get a second opinion.
I took it to Honda and they suggested that replacing the speed sensor should help with the warning lights.
As for the P2720 code, they suggested changing the transmission fluid first in hopes that it solves my issues. If it doesn't fix it, they said that you can't just change a valve, you have to change the entire valve body.
Changing the valve body isn't a guaranteed fix so I might end up needing to replace the transmission anyway

Anyone else run into this P2720 code? Thoughts?

Hi everyone

The speed sensor replacement seemed to have fixed all the warning lights - so that's good
Changing the transmission fluid has been good so far - obviously it could be too early to tell but at least the issues didn't occur driving home

Echoing @Wes Kootenay, does anyone know if it's possible to JUST examine ONE valve? Or is it an "all or nothing" situation?
