Year 6 Issues

[Adrianp89]

Just passed 6 years, coming up on 70k. Some issues starting to flare up. Not sure how much this has to do with the cold. Truck lived in FL for years 0-5 and last year has been TN, where it has been in the 30s.

1. Air Suspension - This just happened.... one corner of the truck seems to be sitting lower after an overnight sit. Seems this is a leak - any one have this resolved? And no I do not want to remove it.
2. Noise when turning right at slow speeds - I know there is a TSB for this, not sure if it will fix it or not. Not sure why it would happen now rather than sooner.
3. Getting some shaking around 80mph. - Probably tires as they are coming up for replacement but any other thoughts here are useful.
4. Drivers door perimiter entry stopped working some time back. - Easy fix and have the part numbers. Want to swap out doorhandles to remove chrome anyways.
5. Bubbling Dash - happened right before year 6, disappointing on this one. Garage kept with ceramic tint on windshield. - Need to check with dealer to see if there is anything they will do.
6. Service 4WD light - happened right before 6 year mark. Swapped out actuator with a $60 one from amazon - so far so good.
7. Transmission is getting a little harder shifts - thinking time to replace the fluid. Anyone do this and get back smoother shifting?

No comment on others than #7.
I replaced the filter/pan and refilled at 80 k or so.
Did not have any issues with shifting but felt the need to do it despite RAM stating for it to be "lifetime" fluid.
The stuff that came out was black but did not appear burned, minimal towing, just a heavy foot.
I will do it again after my trip down to Saint Pete and Venice for the holidays.

edit:
#1. I would put it into tire jack mode or pull power to the compressor , droop the rear suspension and spray soapy water at the air bag.
Can`t remember how to deal with the protective cover, was it on with hose clamps or something else...
