Yes. Under the hood there is another fuse box. It's in there.

On 1980 and later models, both the turn signal flasher and the hazard flasher are located at the lower left hand and the upper right hand corners of the fuse block respectively. Remove these by pulling them from their connectors.
The lower dash panel may have to be removed to gain access to the unit.

From the Dealers service dept.

I doubt whether even the mechanics have one.

Purchase an after market Service Manual

Start with your fuses under the dashboard by the driver's shin bone. Remember that fuses can be burned out and not show it.
Take a test light or meter and check the contacts on each end where the fuses go, with the key on, and the lights on, to be sure there is electricity getting to the fuse.
After that, check each light bulb in the rear of the car.
Remember, the bulb can be burned out and not show.
Also check your clearance lights on the rear.
Take a test light or instrument and check all the sockets to be certain the electricity is getting to the socket when the lights are on and when the brake pedal is pressed.
God bless your efforts.

What do you want it to change into? If you are saying the trans doesn't shift into the next gear soon enough, could be vacuum leak, dirty filter in trans, someone put a different governor in trans. Most likely vacuum leak. Use gauge to test while driving.

yes you need the correct clips and it's real hard to install the bottom rail if the top and side rails are already on since the sides go over the bottom and the top goes over the sides to keep it from leaking.
