Yo natemartin619,
Welcome!
Is Check Engine Light (CEL) on with engine running or in reverse?
It 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.
Same for:
E4OD Transmission Control Indicator Light (TCIL), it is a LED and overdrive on/off switch at end of the Transmission shifter stalk; flashing OD light is an indication of a transmission related trouble code in the Powertrain Control Module (PCM).
Is it flashing eith engine runniing or in Reverse or was it flashing when last driving?

DIAGNOSIS AND TESTING
Diagnosis by Symptom
The Diagnosis by Symptom Charts give the service technician diagnostic information, direction and possible components, using a symptom as a starting point.
The Diagnosis by Symptom Charts are divided into two categories: Electrical Routines, indicated by 200 series numbers, and Hydraulic/Mechanical Routines, indicated by 300 series numbers. The Electrical Routines list the possible electrical components that could have caused or contribute to the symptom described. The Hydraulic/Mechanical Routines list the possible hydraulic or mechanical components that could cause or contribute to the symptom described.
Diagnosis by Symptom Chart Directions
Using the Diagnosis by Symptom Index, select the Symptom/Concern that best describes the condition.
Turn to the Routine indicated in the Diagnosis by Symptom Index.
Always begin diagnosis of a symptom by using the following:
Preliminary Inspections
Verification of Condition
Check the Fluid Level
Perform Other Test Procedures as directed
NOTE: Not all concerns and conditions with electrical components will set a diagnostic trouble code (DTC). Be aware that the components listed may still be the cause. Verify proper function of those components prior to proceeding to the Hydraulic/Mechanical Routine listed.
THEN BEGIN with the Electrical Routine if indicated. Follow the reference or action required statements. Always perform the On-Board Diagnostic Tests as required. NEVER SKIP STEPS. Service as required. If the concern is still present after electrical diagnosis, then proceed to the Hydraulic/Mechanical Routine listed.
The Hydraulic/Mechanical Routines list possible hydraulic or mechanical components that could cause the concern. These components are listed in the removal sequence and by most likely cause. You must inspect all components listed to ensure proper repair.
Engagement Concern: No Forward Only
Possible Component Reference/Action
201 — ELECTRICAL ROUTINE
No Electrical Concerns
301 — HYDRAULIC/MECHANICAL ROUTINE
Fluid
Improper level
Adjust fluid to proper level.
Condition
Inspect per instructions under Fluid Condition Check.
⊙ miesk5 Note; FLUID should be red, not brown or black. Odor may indicate overheating condition, clutch disc or band failure. Use an absorbent white facial tissue and wipe the fluid level indicator. Examine the stain for evidence of solid particles and for engine coolant signs (gum or varnish on fluid level indicator).
A shop may suggest changing filter and new fluid. Read more about the filter being a perpetrator below,
⊙
Shift Linkage (Internal/External) or Cable
Damaged, misadjusted, disconnected.
miesk5 Note; have you run over anything lately ir through water?
Inspect and service as required. Verify linkage adjustment as outlined. After servicing linkage, verify that the Transmission Range (TR) sensor is properly adjusted. Refer to In-Vehicle Service in this section.
Improper Pressures
Low line pressure; miesk5 Note; best done by a shop.
Check pressure at line tap. Perform Line Pressure and Stall Speed Tests. Refer to Pressure Chart No. 401 for specification. If pressures are low, check the following possible components: Pump inlet filter and seal assembly, main controls, pump assembly, forward clutch assembly.
Filter Assembly and Seal
Plugged, damaged
Inspect filter assembly and seal for damage.
Filter seal damaged, cut
Replace as required.
Main Controls
Manual valve stuck, damaged
Inspect for damage and service as required.
Control body housing leakage
Bolts not tightened to specification
Retighten bolts to specification.
Gaskets damaged
Inspect gasket for damage and replace as required.
Forward Clutch Assembly
Assembly
Air check clutch assembly as outlined in this section.
Stator support seal damaged
Inspection damage. Service as required.
Piston, seal; check ball damaged, missing, not seating
Inspect seals for damage, check ball seating, location. Service piston assembly as required.
Feed bolt loose, missing
Install new feed bolts and tighten to specification.
Center support damaged, holes blocked/missing
Inspect for damage. Service as required.
Forward clutch sealing rings damaged
Inspect for damage. Service as required.
Forward clutch ring gear damaged
Inspect for damage. Service as required.
Friction elements damaged, worn; spline teeth damaged, missing
Check for abnormal wear, damage. Service as required.
Stator support seals damaged
Service as required.
Forward/Reverse Sun Gear Damaged
Inspect for damage. Service as required.
Front Planet Assembly Damaged
Inspect for damage. Service as required.
Output Shaft
Splines damaged
Inspect for damage. Service as required.
Low One-Way Clutch Assembly (Planetary)
Worn, damaged or misassembled
Inspect for damage. Service as required.
Hard for me to determine if gunk and metal shavings are excessive.

4WABS Self Test & Test Connector Diagram, Component Locations, DTCs, 93-96; USE THIS PROCESS! "...The 4WABS TEST Connector is red; located at the left-hand side (driver's side) of the engine compartment and marked ANTI-LOCK TEST; Light Flash Technique 1. Note: If 12V test light is not available, the amber ABS warning light also flashes during this test. Locate test connector in the engine compartment and install 12V test light between Pins C and E. 2. With the ignition off, jumper Pin E to B. 3. Turn key to RUN position. 4. Remove jumper between Pins E and B after 5 seconds. 5. Count light flashes of test light or amber ABS warning light..." read more; miesk5 Note; for all Resistance tests, battery needs to be disconnected; remove Negative cable at battery

Parking Brake Inspection & Cleaning in a 96 from the 1996 F-150, F-250, F-350, and Bronco Workshop Manual; "...Inspect the parking brake control (2780) and look for loose mounting bolts, damaged or missing parts. Operate the parking brake and check for binding or seized components. Raise and support the vehicle and remove any debris that may interfere with parking brake operation. Check the condition of the parking brake cables. Look for abrasion or cables rubbing on body or frame parts. Repair, replace or reroute as necessary. Remove the brake drums (1126) and have an assistant operate the parking brake just enough to observe operation. Look for damaged or missing parts. Lubricate parking brake parts with Disc Brake Caliper Slide Grease D7AZ-19590-A or equivalent meeting Ford specification ESA-M1C172-A..."
