The 2000 Ram 1500 is a workhorse truck with solid axles and a simple design, but it's plagued by transmission failures, intake manifold gasket leaks on V8s, and concerning engine wear issues that can lead to catastrophic failure if neglected.
46RE/47RE Transmission Failure
Common · high severityTypical onset: 90,000-150,000 mi
Symptoms: Harsh 2-3 shift or slipping in overdrive, Delayed engagement when shifting to drive or reverse, Transmission overheating, especially when towing, Metal shavings in fluid during service
Fix: Rebuild typically requires 8-12 hours labor; includes clutch packs, bands, solenoid pack, and torque converter. The cooler lines and external cooler often need replacement simultaneously. Many shops recommend upgraded clutches and bands during rebuild.
Estimated cost: $2,200-3,800
Intake Manifold Plenum Gasket Failure (5.2L/5.9L V8)
Common · medium severityTypical onset: 75,000-130,000 mi
Symptoms: Rough idle and hesitation on acceleration, Check engine light with lean codes (P0171/P0174), Whistling or hissing sound from engine bay, Oil consumption increase as gasket degrades further
Fix: Requires removal of upper intake plenum to replace the deteriorated composite gasket, typically 3-4 hours labor. Smart shops replace with aluminum aftermarket gasket to prevent recurrence. Often find oil sludge buildup in plenum during this job.
Estimated cost: $450-750
Premature Engine Bearing Wear Leading to Knock
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Rod knock on cold start that may quiet down when warm, Low oil pressure at idle (under 10 psi), Metallic ticking that worsens under load, Sudden catastrophic failure if driven with knock
Fix: Caused by inadequate oil changes or sludge buildup in Magnum engines. Repair requires complete engine teardown for bearing replacement (15-20 hours) or short block swap (12-16 hours). Machine work adds cost if crankshaft is scored. Many owners opt for used engine swap instead.
Estimated cost: $3,500-6,500
Front Ball Joint Failure
Common · high severityTypical onset: 80,000-120,000 mi
Symptoms: Clunking over bumps from front suspension, Wandering or loose steering feel, Uneven tire wear on inside edges, Visible play when prying on tire with truck on lift
Fix: Upper and lower ball joints wear out, especially on 4WD models. Uppers are bolt-in (easier), lowers require pressing or replacement of entire control arm. Plan 4-6 hours for both sides with alignment. Always do both sides simultaneously.
Estimated cost: $600-1,100
Dashboard Cracking
Common · low severitySymptoms: Cracks along top of dashboard near windshield, Material becomes brittle and splits, especially in sun-exposed trucks, Purely cosmetic but unsightly
Fix: The dashboards in these trucks are notorious for cracking due to UV exposure and material defects. Replacement requires complete dash removal (8-10 hours). Most owners live with it or use a dash cover.
Estimated cost: $800-1,500
Fuel Pump Failure
Occasional · high severityTypical onset: 100,000-150,000 mi
Symptoms: No-start condition or extended cranking before start, Stalling or stumbling under acceleration, Whining noise from fuel tank, Loss of power at highway speeds
Fix: In-tank pump accessible by dropping the tank (2-3 hours labor). Replace strainer and check sock simultaneously. Running tank below 1/4 repeatedly accelerates pump death.
Estimated cost: $450-750
HVAC Blend Door Failure
Common · low severityTypical onset: 80,000-140,000 mi
Symptoms: Stuck on heat regardless of temperature setting, Clicking or snapping noise from dashboard when adjusting temperature, No air flow change when switching between hot and cold, Driver side different temperature than passenger side
Fix: Plastic blend door breaks inside heater box. Full repair requires complete dash removal (12-16 hours) to access. Many owners install aftermarket bypass door kits that can be installed in 2-3 hours through glove box opening as a workaround.
Estimated cost: $1,200-2,000 (full repair), $150-300 (bypass fix)
Buy one only if it has documented transmission service history and no engine knock—budget $2,000-3,000 for deferred maintenance on any high-mileage example.
