2 issues.

Yesterday while cruising at 80k felt like engine lost drive.
Engine started revving hard and car slowed
I got it home but further driving felt like it was shifting down and up by itself.
I have noticed the oil px has been high.
And yesterday it got up in the red.

So possibly the oil sender unit needs changing.
Will that affect the shift solenoids.
I read also that the shift inhibit switch may be an issue.
Thx
