Transmission problem.

I have a 1996 bronco, it’s a 5.8L and I recently been having transmission problems and finally it gave out, not see if the transmission is done or not it will go into reverse, but not drive whenever I put it in drive it just sits there but it will go in reverse and drive, I haven’t check for any codes but the abs light is on, also the parking brake light is on but parking brake is not engaged, I drained the transmission yesterday, and there was a lot of gunk and metal shavings in the bottom of it, any suggestions on what to do or if the transmission is done. Thanks for any help you guys and give me!

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.

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..."

The Check engine light was on when I bought it but it recently went off, and last time I drove it the overdrive light was blinking and it was shifting hard.

Yo,

Key phrase is "overdrive light was blinking and it was shifting hard."

See what the code scan will retrieve.

Check Engine Light (CEL) Overview in a 96; "...The light comes on briefly when you turn the ignition key to ON, but it should turn off when the engine starts. If the light does not come on when you turn the ignition to ON or if it comes on and stays on when you are driving, have your vehicle serviced as soon as possible. This indicates a possible problem with one of the vehicle’s emission control systems. You do not need to have your vehicle towed in. If the light turns on and off at one (1) second intervals while you are driving the vehicle, it means that the engine is misfiring. If this condition persists, damage could occur to the engine or catalytic convertor. Have your vehicle serviced at the first opportunity. You do not need to have your vehicle towed in. If the light turns on and off on rare occasions while you are driving, it means that a malfunction occurred and the condition corrected itself. An example of a condition which corrects itself occurs when an engine running out of fuel begins to misfire. In this case, the Check EngineWarning Light may turn on and will then set a Diagnostic Trouble Code DTC) indicating that the engine was misfiring while the last of the fuel was being consumed. After refueling, the Check Engine Warning Light will turn off after the vehicle has completed three consecutive warmup cycles without a misfire condition occurring.A warm up cycle consists of engine start from a cold condition (engine at ambient temperature) and running until the engine reaches normal operating temperature. On the fourth engine start up, the Check EngineWarning Light will turn off as soon as the engine begins to crank. It is not necessary to have the engine serviced. Under certain conditions, the Check EngineWarning Light may come on if the fuel cap is not properly installed. If the Check EngineWarning Light comes on and you suspect that the fuel cap is not properly installed, pull off the road as soon as it is safely possible and turn off the engine. Remove and replace the fuel cap, making sure it is properly seated. After completing the three consecutive warm upcycles and on the fourth engine start up, the Check Engine Warning Light should turn off. If the light does not go off after the fourth engine restart, have your vehicle serviced by your dealer or a qualified technician..." by Ford
