P0767 - Code - Shift Solenoid "D" Stuck On

As the title says, this code came on and the AT and check engine light as well as hard shifting out of 1st(maybe 2nd) gear. I drove it home fairly slowly. I have a 2010 3i sedan w/ 2.0 engine and automatic transmission. Looking at the manual, the shift solenoid D is the same as shift solenoid E and they are on the same side. Where do you suggests I buy one from? Should I replace both D & E? I'm in California. Rockauto has "ATP NE25 {#XS4Z7H148AA} Shift SSD & SSE On/Off Solenoid 2 per Unit" and NAPA has "Automatic Transaxle Solenoid Part #: ATP 16711 Line: NAPA Automatic". Both have the exact same product image but different part numbers. Any suggestions as to which to buy and from where is greatly appreciated. I'll also try calling the closest mazda dealership Monday morning.Thank you!

ALSO: the manual says to use silicon sealant (TB1217E) for the trans oil pan. Can I use regular Permatex Black RTV silicone gasket maker or should I use something else?
How many quarts of transmission fluid need to be replaced if I remove the trans oil pan? Thanks!!

EDIT: the car has 240k miles. The other "E" solenoid was replaced about 100k miles ago. The tcm was rebuilt/repaired about 2k miles ago after developing the u0101. Since then, the car has driven without any transmission related issues. The p0767 code and the hard shifting that comes with it came on out of nowhere just like when the other solenoid messed started messing up.

Solenoid codes on our vehicles can often be caused by TCM issues, so I recommend testing the solenoids before replacing anything. The solenoid connector is not difficult to access, once the air box has been removed. At the connector you can do resistance testing, and also operate the solenoids by applying voltage and ground.

But if you do wind up removing the tranny pan, then you might consider a solid gasket instead of RTV. I used a Felpro gasket when I did the filter, and there's been no leaks for however many years it's been since I did the work.

Okay. I'll look into a solid gasket instead of rtv. I added some more context.
