Help with some error codes...Transmission Malfunction

Hi guys, I posted about a month ago that I received Transmission Malfunction error when I was leaving the gym and merging into the highway. Long story short, I gave it gas to merge and once I hit about 30-40 mph, the power was not there, I heard the RPMs get Loud and I had to stay at about 30 mph because the vehicle would not go faster, Very scary moment.

I had a few friends with regular hand held scanners who got codes: 400441 Ratio Monitoring Clutch E Implausible. Another gave codes: 210901 Alternator no communication and cd930.

I posted that here on the forums and was mentioned to get insta+. Finally after downloading it and buying a windows laptop, I have installed it successfully and managed to scan my 7 series but honestly, I have no idea where to start regarding the codes.
I am posting the screen shots and maybe someone knows about it.

I believe that under the "Is currently present" tab, 2 say they are "unknown" and are the Current main errors.

1. 400341 Ratio monitoring, gearshift 4-5 implausible ( I think this is the 400441 Ratio Monitoring Clutch E implausible that one of the hand held scanners got)

2. 481F81 RDC: Internal Control-Unit Fault ( I believe this is the TPMS error for the tires)

3. 8029C7 Locking Protection + 400641 Parking Gear Incorrectly engaged ( I think this is the reason why when I start my car, put it in Drive, it will Pause a few seconds and then go back to Park on its own. I shift again to Drive and it will take like 5 seconds before actually moving)

Prior to this which all happened in June...Back in January/February, I got my valve stem seals replaced under the lawsuit. They gave me a new battery as well. I paid to get my turbo coolant lines replaced as well since the rep recommended this.
One other thing, I noticed back in winter time when the weather was very cold, I got drivetrain malfunction error in November 2018

Also, regarding Ista+, once I am done getting my codes for my car, how do I "safely" exit out of the program? Just take out the ENET cable?

Thank you in advance for any help that you guys can offer. I greatly appreciate it.
