A nightmare gearbox failure

[CyberMage]

Greetings everyone,
Is anyone able to lend a hand?
Unfortunately, my gearbox (9-speed automatic) is giving me trouble.
Occasionally during the past few months.
The gear selector didn't rise once, but after that, everything was fine.Afterward, the gearbox restarted and the vehicle entered limp mode.
After a few more dash warnings, it resolved itself.
It was either the gear box or the gear selector, according to my independent mechanic. I noticed that the gearbox reset fixed the problem, but now I can't select sport. There is a bit of a bump between 3/4 of the time, but it's not all the time.

It is unclear if Indie was unaware because he did not provide codes.
Biting the bullet and finishing the gear selector is on my mind.
After perusing the links provided, I have
Is anyone out there thinking anything?
Appreciate you taking the time to read this

Good day,

My advice would be to invest in a code reader, but I'm not much of a help. In all likelihood, you will have the opportunity to retrieve codes at some point.
Taking chances and exchanging components can turn into a costly pastime!

Much obliged

Are you sure the battery is fully charged? OK, buddy.

Hello there! It's fourteen months old, fully charged.
I am grateful.

Is there an additional battery in your vehicle? Have you made sure to check?

[CyberMage]

I appreciate your advice; my indie does not mention that.

My car was a veritable Christmas tree of lights until I discovered the problem—a faulty rear speed sensor—and had it replaced. I highly recommend getting a code reader, like the Icarsoft LR 3.
