I would double check those fluids remembering they should be checked warm with the engine running after shifting into all gear options. If this does not work you may have an electrical problem preventing all the necessary solenoids from activating. Your best shot may be to drive it to a repair shop and have them diagnose it. If it is only the solenoid the fix shouldn't cost that much.

Sounds like your connection for the screen may have come loss during reassembly. I am not familiar with your exact device, however if it is possible to disassemble the phone again and check your work I would recommend that first. If the problem persist beyond that then it may be a defective replacement screen or you may have damaged your device during the repair process.
Overall I would say you would be wasting time and money on this laptop. A ram upgrade may well "speed up" the machine (it doesn't actually speed it up it just allows it to handle more). As for the battery mac's are very picky and a battery is far more than just cells, they also have a circuit board in them which controls many things. It has been my experience when replacing mac batteries with third party batteries that it often creates more issues such as random shutdowns triggered by unexpected readings from the new battery. So either buy a apple battery, be prepared for problems or some people say to swap out the brains of the battery from your old one to the new one. That however is a lot of trouble. The other issues you are having could be attributed to many things from lose connections to failing hardware. I would need a little more info to further diagnose. i.e. does it shut down or does it just turn off. What if anything shows on the screen ect. The information you can provide in this manner the...
Since I do not have these exact two laptops in my possession I cannot say for sure. However, they look close enough that I would suspect a majority of the parts are the same. In short if it fits and plugs in it will work.
The reason you have heard this is because the hard drive in your mac book is a solid state drive that has a not sata connection type. You can search for 2014 Mac Book Pro hard drive enclosure on google and find some enclosures that would allow you to connect it to another computer via usb. If you want to make sure that you get your data then you could take it to the big blue box store and see the guys there. They can send it off and have all the data extracted minus programs. It is rather expensive and time consuming though.
For the sake of doing so I would recommend blowing the charging port out with some compressed air. Beyond that it looks like the charging port is separate from the main board so it could be that it simple needs to be replaced or re seated (unplugged from the main board and plugged back in). If you have an electronics store near by you can buy a charging cable with chasing lights in it. They are kinda novelty cables however they are excellent for troubleshooting power issues. The lights only stay on if the device is taking power, the faster the lights are going the more power the device is taking.
Hi Jane, This sounds like a network issue since there are multiple devices involved with multiple issues. I would advise contacting your service provider and telling them about the issue. Of course you should always try turning off and back on again, (make sure you turn the whole phone off and not just the screen). I would not suspect a software update causing this as a bug that obvious would have been caught in testing.
