Yo 96FORDBRONCOEB,
Try to get it to a parts store that will scan for codes for fee.
Also the Check Engine Light (CEL) comes on when the electronic engine control system is not working properly. The check engine warning indicator comes on briefly when the ignition switch lock cylinder is turned to ON, and should turn off when the engine starts. If the check engine warning indicator does not come on when the ignition switch lock cylinder is turned to ON or if it comes on while the vehicle is moving, the system is malfunctioning
If the CEL does not light up at all when starting it; then suspect that bulb is burnt-out or loose, socket was damaged by PO or shop, etc. or someone removed it.
Does it light up as described?
OverDrive light on the column: Transmission Control Indicator Light (TCIL) Troubleshooting in 92-96; "... Several different complaints concerning the overdrive cancel indicator may occur due to a faulty O/D cancel LED. At times the light may simply fail to light, flicker erratically, or glow very dim. Tapping the shift **** lightly may affect the operation of the LED, causing it to work temporarily. These complaints are usually due to a faulty O/D indicator LED. To replace the LED carefully pry the cap off the end of the shifter and pull the LED/switch out. Slide the new switch into position and snap the cap back on. Note: Don’t confuse the above conditions with a steady flashing pattern of the O/D cancel light. A steady rhythmic flashing pattern indicates a malfunction has been detected by the computer.; Part #F58Z-7G550-A..." available at our Sponsor, Jeff's Bronco Graveyard

How does fluid look and aroma?
Should be red, and No burnt toast..

DIAGNOSIS AND TESTING
Preliminary Inspection
http://www.diesel-dave.com/vehic/manual/stj/stj71a13.htm#extract_1003
if the transmission is not working properly, for instance, the transmission may slip or shift slowly, or if you notice some sign of fluid leakage, the fluid level should be checked.
It is preferable to check the transmission fluid level at normal operating temperature after approximately 32 km (20 miles) of driving. However, if necessary, you can check the fluid level without having to drive 32 km (20 miles) to obtain a normal operating temperature if outside temperature is above 10°C (50°F).
With the vehicle on a level surface, start the engine and move the transmission gearshift selector lever through all of the gear ranges allowing sufficient time for each position to engage. Securely engage the transmission gearshift selector lever in the park position, fully set the parking brake control (2780) and leave the engine running.
Wipe off the fluid level indicator cap, pull thefluid level indicator (7A020) out and wipe the indicator end clean. Put the fluid level indicator back into the fluid filler tube and make sure it is fully seated. Pull the fluid level indicator out and read the fluid level.
CAUTION: The vehicle should not be driven if the fluid level is below the bottom hole on the fluid level indicator and outside temperature is above 10°C (50°F).
When checking fluid at normal operating temperature, the fluid level should be within the crosshatched area or HOT marked area on the fluid level indicator. When the vehicle has not been driven, and outside temperature is above 10°C (50°F), the fluid level should be between the holes or COLD marked area on the fluid level indicator.

This show some tests that probably can not be done at home, but at least you will know what a shop or Ford tech. will do.
Pick a few that is close to the issue, such as:
Engagement Concern: Delayed/Soft Forward and Reverse
Possible Component Reference/Action
209 — ELECTRICAL ROUTINE
Or,
No 1st Gear in Drive, Engages in Higher Gear
btw, "Run On-Board Diagnostics" is the code scan
Or,
Shift Concerns: No 1-2 Shift (Automatic)
Possible Component Reference/Action
220 — ELECTRICAL ROUTINE
