I pulled code P0752 from my truck and after a bit of googling it sounds like it could just be dirty or blocked by debris.
Is this something that can be easily taken care of with basic tools?
Which one is solenoid A?

I'm mechanically inclined enough to do the work but I haven't worked on transmissions or any OBD 2 vehicles before.

Hello, I'm Danny.

Taking the transmission pan off to get to the solenoids are just normal hand tools. The only specialty tool you would need is a professional scanner to aid in diagnosis and to program the new solenoid to your truck. Here are two tutorials show how to test wiring and how to service an automatic transmission:

I've attached picture diagnostic steps below to help determine the cause of the code on your truck. Hope this helps and thanks for using 2CarPros.
