The 2004 Town & Country is a solid workhorse minivan, but the 41TE/41TES 4-speed automatic transmission is its Achilles' heel. Expect transmission issues and related cooling system failures as the primary concern, along with typical Chrysler 3.3L/3.8L upper engine problems.
41TE/41TES Transmission Failure
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: Harsh or delayed 2-3 shift, especially when cold, Slipping in overdrive or refusing to upshift, Limp mode with P0700/P0731-P0734 codes, Shuddering during light acceleration
Fix: Full rebuild or reman replacement. Input and output speed sensors fail frequently and should be replaced preventively during rebuild. Solenoid pack and valve body wear are common culprits. Budget 8-12 hours labor for R&R and rebuild, or 6-8 for reman swap.
Estimated cost: $2,200-3,800
Transmission Oil Cooler Line Corrosion and Leaks
Common · medium severityTypical onset: 70,000-120,000 mi
Symptoms: Pink ATF fluid puddles under front of vehicle, Transmission overheating, especially towing or highway driving, Low transmission fluid level on dipstick, Rust visible on steel cooler lines at radiator connections
Fix: Replace both steel lines from transmission to radiator-mounted cooler. Lines rust through where they pass under the vehicle. Often discovered during transmission failure diagnosis—leaking cooler starves the trans of fluid. 2-3 hours labor, must drop crossmember for access.
Estimated cost: $350-600
Intake Manifold Plenum Gasket Failure
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Rough idle and stalling when cold, P0171/P0174 lean codes, Whistling or hissing sound from engine bay, Loss of power on acceleration
Fix: Upper plenum gasket deteriorates and causes large vacuum leak. Replace upper and lower intake gaskets as a set—lower can leak coolant into crankcase. 4-5 hours labor. Use updated composite gaskets, not original paper style.
Estimated cost: $450-750
Transmission Mount Collapse
Common · low severityTypical onset: 80,000-130,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive engine movement visible during acceleration, Vibration at idle in gear, Transmission tunnel heat in cabin
Fix: Hydraulic rear transmission mount fails, allowing drivetrain to sag and shift excessively. Replace mount—requires supporting transmission from below. Often done with transmission service. 1.5-2 hours labor.
Estimated cost: $200-350
Power Steering Pump Pulley Seizing
Occasional · medium severityTypical onset: 90,000-140,000 mi
Symptoms: Squealing serpentine belt that doesn't stop with new belt, Hard steering or complete loss of power assist, Burning rubber smell, Belt thrown off pulleys
Fix: Power steering pump bearing fails, locking the pulley. Can shred serpentine belt and leave you stranded. Replace pump and flush system—old fluid accelerates failure. 2-3 hours labor.
Estimated cost: $400-650
EGR Valve and Tube Carbon Clogging
Occasional · low severityTypical onset: 100,000-150,000 mi
Symptoms: Rough idle and surging at steady cruise, P0401 insufficient EGR flow code, Hesitation during light acceleration, Poor fuel economy
Fix: EGR passages and valve clog with carbon, especially on 3.3L. Remove intake plenum, clean passages with carburetor cleaner and wire brush, replace EGR valve. 3-4 hours labor combined with plenum gasket service.
Estimated cost: $300-500
Evaporative Emissions System Leaks
Occasional · low severityTypical onset: null
Symptoms: P0442 small EVAP leak or P0455 large leak codes, Fuel smell after filling tank, Check engine light after refueling, Failed emissions test
Fix: Leak detection pump, purge solenoid, or vapor canister commonly fail. Gas cap is rarely the actual problem despite being cheap to replace. Requires smoke test to pinpoint. LDP replacement is 1-2 hours; canister is 2-3 hours.
Estimated cost: $250-600
Buy one under 100,000 miles with documented transmission services, or budget $3,000 for an eventual transmission rebuild—everything else is manageable.
