Engine rpms rise and also engine bogs down a little when it does?

Engine rpms rise to 4,000 to 5,000 RPMs before shifting when first taking off And I used a scanner trying to check for codes wasn’t any in transmission but I am did see something about lubricating line pressure and it was the only thing in red it was negative 73 but I saw another vehicle that had this and when they put it in drive and took off the pressure went positive so idk if that’s supposed to be that way at idle or not but I do know the RPM is rising to 4,000 RPMs before shifting. I don’t want the car to mess up.

Does this car have 2,000 miles on it? What was the codes number? Is the transmission leaking or low on fluid?

It has 2,000 miles on it and there’s no engine codes on it just past codes from the factory I guess but nothing new and took it to dealer they said it does as should but now it’s also the rpm is dropping to almost 0 and shaking and it cut off.

It sounds like you have a vacuum leak, I would go over this video to see what you can find.
