On the 1990-1994 Ford Ranger, on Rangers with the A4LD 4-speed automatic, when the shift lever is placed in Park the park pawl does not always abut/engage the park gear. The driver believes the truck is safely in Park, but the pawl can slip, allowing the vehicle to roll away on a slope or move unexpectedly when started. This was the subject of NHTSA safety recall 91V189000, announced November 4, 1991, covering roughly 792,000 Ford light trucks/vans of this era.

Common Symptoms

  • Truck appears to be in Park but rolls away on an incline
  • Vehicle creeps or lurches when started in Park
  • Shifter feels like it seats in Park but drivetrain is not locked

How to Fix

Per NHTSA Campaign 91V189000, the fix was a new/revised park pawl to ensure positive engagement of the park gear. Owners of an affected truck should verify the recall was performed via the VIN. As a standing best practice on any 1990s Ranger automatic, always set the parking brake before shifting to Park.

Typical repair cost:$0 - $300

On the 1990-1995 Ford Ranger, the A4LD automatic (used through the mid-1990s before the 4R44E/5R55E) has a long, well-documented history of driveability and durability problems. Common failure points are the two shift/lockup solenoids, the overdrive sprag, worn bands, and a governor on the output shaft that sticks with debris (holding it in first gear). A misadjusted throttle-valve/kickdown cable causes slipping that burns clutches. Reliability improved after the dual-solenoid update, but these units remain a known weak point on 1990s Rangers, especially with towing or neglected fluid service.

Common Symptoms

  • Slipping, especially under load or during the 3-4 shift
  • No overdrive / harsh or no upshift
  • Stuck in first gear (sticking governor), often when cold
  • Delayed engagement, flare between gears
  • Torque converter lockup shudder

How to Fix

Diagnose specifics first: adjust the TV/kickdown cable and service fluid/filter for early slipping; replace failed solenoids; free or replace a stuck governor. A worn overdrive sprag, slipping bands, or burned clutches typically require a full rebuild. Keep fluid fresh and avoid overloading. Many owners upgrade to a rebuilt unit with updated hard parts and an auxiliary cooler.

Typical repair cost:$1,500 - $2,800

On the 1994-2010 Ford Ranger, the 4.0L V6 uses a waste-spark coil pack with only three coils firing six plugs in paired cylinders, and it has a high failure rate — especially the end of the pack that serves the paired 3 & 4 cylinders (they share a secondary winding). A failing coil makes the misfire jump between the two paired cylinders, throwing P0300 plus paired cylinder codes, rough running and hesitation. Aged plugs and cracked plug wires compound it.

This issue also affects: Ford Aerostar, Ford Bronco, Ford Bronco Sport

Common Symptoms

  • Rough idle / shaking
  • P0300 random misfire plus paired cylinder codes
  • Hesitation and power loss
  • Flashing check engine light under load
  • Poor fuel economy

How to Fix

Swap the suspect coil pack to a different position — if the misfire follows the coil, the coil is bad (replace the coil pack; Motorcraft DG-series). Inspect the coil harness for burnt/frayed wiring, and replace the spark plugs and plug wires with correct Motorcraft parts as a set. Verify no vacuum leak (a lean condition can also set random misfire).

Typical repair cost:$100 - $400

On the 1990-1999 Ford Ranger, the 3.0L Vulcan and 4.0L Cologne OHV V6 engines use a camshaft synchronizer (a cassette that replaced the old distributor) which houses the camshaft position sensor and also drives the oil pump via a gear on its shaft. The aluminum housing receives no forced (pressurized) lubrication, so the upper bushing dries out and the shaft begins to squeal. It is one of the most commonly reported wear items on 1990s OHV Ranger V6s and gets worse with age and mileage.

This issue also affects: Ford Expedition, Ford Explorer, Ford F-150

Common Symptoms

  • Loud chirp/squeal/screech from the front of the engine, usually worse when warm
  • Erratic, intermittent squeaking that mimics a belt squeal
  • On repeat/eventual failure: bucking, stumbling, hard starting or stalling, sometimes with no noise
  • Check-engine light for camshaft position sensor
  • Catastrophic loss of oil pressure if the oil pump drive gear shears

How to Fix

Replace the camshaft synchronizer assembly along with the camshaft position sensor, using the special synchronizer alignment/timing tool so the CMP sensor is indexed to the correct position (mis-indexing throws timing off and causes driveability faults). Enthusiasts strongly recommend a Motorcraft synchronizer over cheap aftermarket units, which have been reported to fail again in as little as 10,000 miles. Because the shaft drives the oil pump, a total failure can shear the drive gear and drop oil pressure to zero, destroying the engine; address the chirp early.

Typical repair cost:$150 - $400

On the 1990-1999 Ford Ranger 3.0L Vulcan OHV V6, the 3.0L Vulcan V6 is notorious for a coolant leak at the aluminum front timing cover. The dissimilar-metal joint (aluminum cover against a steel block) plus pitting/corrosion of the aluminum cover causes the gasket to fail and weep coolant. If the leak is ignored and coolant runs low, the engine overheats, and the 3.0L is prone to cracking cylinder heads and blowing head gaskets when overheated.

Common Symptoms

  • Coolant seep/drip at the front timing cover
  • Sweet coolant smell, low coolant, spots under the front of the engine
  • Overheating if coolant runs low
  • Coolant in oil / white exhaust smoke if a head cracks or head gasket fails

How to Fix

Replace the timing cover gasket (use quality gaskets with black RTV around the large coolant passages so the joint stays sealed against dissimilar-metal expansion, and thread sealant on the bolts that pass into the water jacket). Note that two bolts pass through the oil pan into the cover, so the oil pan gasket is often disturbed and should be replaced at the same time. If overheating already occurred, pressure-test for a cracked head/blown head gasket. Address leaks early to avoid the far costlier head damage.

Typical repair cost:$400 - $1,000
