Electrical, TIPM, headlight

I’ve replaced the headlights in my car four times in the past year and recently the passenger side bulb went out and installing a new bulb did not fix the issue. Additionally in the last year there have been three occasions where after start up my transmission is stuck in low gear. The only fix seems to be shutting the car off, waiting a while before starting back up and praying it doesn’t happen again for awhile. Also recently while driving the parking brake dash light will come on out of nowhere only to go away after 30 seconds or so. I’ve done a decent amount of research over the past week and to my knowledge it looks like all of these issues are tied to the TIPM and that there may be a failed integrated circuit somewhere in the TIPM. From here I’m stumped. I would prefer not to send in the module and rather repair it myself but I haven’t had any luck finding any detailed info about my TIPM online. Just looking for some professional advice I guess.
