RPMs are going up when I press the gas and speedometer needle stay on 0 MPH?

Bummer, it sounds like the CVT transmission has gone out. Do you have a check engine light on? If so, we should run the codes to see if any point to a bad transmission. I would remove the transmission dip stick to see if the fluid is burnt up, if so, I would not mess with it and have a new or rebuilt unit installed. But let's run the codes first.

Yes I have the check engine light on.

Yep, these are the codes you get when the belt goes out inside the CVT unit. Did you check the fluid condition?

No, I haven’t checked yet. Should I buy a new transmission or just sell the car? It has over 225,000 miles.

That is up to you, judge how good the condition of the car is and weigh your options. Car payments last 5 to 6 years. I tend to lean towards repairs as a one-time deal but if the car is in bad shape you may want to go a different route.

I have other repairs to do and is it the transmission going bad or do I need transmission fluid?

You might just need fluid, have you checked it?

Yes, I checked the transmission fluid and it barely any fluid on the stick and it is brown.

Oopps, that is no good, I would fill the fluid and see if anything has changed, if not it sounds like the transmission has gone bad. Sorry.

Do I take the car to get that done?

Yes, if you want to keep the car you need to have a new/rebuilt transmission in it.

So adding transmission fluid isn’t going to solve this issue ? And it is the transmission.

"I would fill the fluid and see if anything has changed," was what I thought you did. So did you add fluid and did it change anything?

i had fill the fluid.

Yep, bummer, it looks like the transmission will need to be rebuilt, the belt is burned up and not holding like it should, this is a super common problem with these cars. Thanks for the video, it helped.
