Codes 7E8 and 7E9 A/T

Hi Jacob, I'm having those same two codes come up 2008 Jeep Patriot. First one says lost communication with TCM second says my reader doesn't have the code stored.

Hi, i'm having these same codes going on. Before any codes came up, I was having the car act like it's going stall going 50/60 MPH. I have been hearing a metal rattle under my seat that is exhaust related.
It stalled out while driving through town, and the engine light lit up. I put dry gas in it, and got gas, and then it wouldnt start at all. Finally got it started, but it still has two dash lights on, and it's still going to happen.
My vehicle is a Jeep compass, 2015, 2.4, 137,000 miles, 4x4 with an automatic transmission.

My scanner is a Walmart scanner.

So, I bought a 2008 Jeep Patriot Sport 2.4L CVT Transmission about a little over a month ago from a used dealer. So far, we've had to unclog the sunroof drains, replace thermostats, replace radiator, change spark plugs, do a transmission fluid exchange and filter change, oil change, change all the other filters, and about to replace the front and rear struts. Well, a few days after enjoying the smooth ride from changing out the transmission fluid, the car did what I call a hiccup. While I was trying to accelerate to a faster speed or continuously going the same speed (highway drive for both incidents), it would temporarily lose power and then come right back. A hiccup. So that is what led to the spark plug change and finding out the radiator had this gnarly crack in it and it was like some Slimer stuff was spraying at me. Had no issues the next morning driving the vehicle to go pick up my husband from work. I took the highway there and then drove through town and the last bit was a highway (like three or four exits worth of drive). That night however, yeah no. She hiccupped twice going towards my husband's work on the highway. I told him I would drive through town just to be safe. I am so thankful I did. Anyway, this vehicle quit running three times on me trying to get home. She started right back up after each one but if I did not hold the brake pedal and rev the car while stopped, she would shut off. Mind you she has power, just no gas. I thought, bummer fuel pump went out. No, that was not the messages I got after using my OBDII reader. It came up with 7E8 and 7E9. So, I clicked on the first one. That came up as Crankshaft Position Control Sensor. Okay. It's a plug piece and not too bad. The second one came up as a pressure solenoid stuck on. That one I saw on my 2002 Saturn LW200 when I was needing to replace the filters on the transmission and something else. Once I replaced those that solenoid message didn't come up again. When I went back out to the vehicle to pull up the messages to take a picture of them for my husband and brother, the 7E9 said there was no fault code to show. So that solenoid thing disappeared. The only one that remained was the crankshaft position control sensor. So, would it be safe to say that once I replaced that the 7E9 message would stay gone? Sorry for the ramble. I pushed that 3-ton vehicle by myself. If you want to know what that looks like, think of a midget pushing an elephant. Thanks for the help. Oh, I forgot to take a pic of the "no fault codes" for the 7E9. I was having some breathing issues from pushing the beast.
