2000 DODGE GRAND CARAVAN

Typical onset: 80,000-150,000 mi

Symptoms: Delayed or harsh shifting between gears, especially 2nd to 3rd, Slipping under acceleration or complete loss of forward gears, Transmission overheating, burnt fluid smell, Check engine light with solenoid pack or pressure control codes

Fix: Rebuild or replace transmission. Solenoid pack replacement buys time in early stages (3-4 hours labor), but most need full rebuild (12-16 hours) or reman unit (8-10 hours swap). Always replace transmission oil cooler and flush lines when doing transmission work to prevent repeat failure from contaminated cooler.

Estimated cost: $2,200-3,800

Typical onset: 90,000-130,000 mi

Symptoms: Coolant leaking externally at front of engine, pooling under vehicle, Overheating or erratic temperature gauge readings, White smoke from exhaust if coolant entering cylinders (internal leak), Rough idle, misfires, or coolant in oil (milky dipstick)

Fix: Replace intake manifold gaskets and plenum gasket, flush cooling system. On 3.8L, also common to find cracked plenum chamber causing vacuum leaks. Job requires removing upper intake plenum, fuel rails, throttle body. 5-7 hours labor. Use updated composite gaskets, not OEM paper ones.

Estimated cost: $650-1,100

Typical onset: 100,000-180,000 mi

Symptoms: Excessive oil consumption, burning oil smell, Ticking or knocking from valve train or bottom end, Low oil pressure warning, especially when hot, Rough running, misfires on multiple cylinders

Fix: These engines build sludge if oil changes are stretched past 5,000 miles or wrong oil used. Leads to piston ring failure, scored cylinders, spun bearings. Minor cases may survive with valve cover removal and cleaning (4 hours), but advanced cases need complete engine rebuild (30-40 hours) or replacement longblock (18-24 hours swap). Confirm with borescope before committing.

Estimated cost: $3,500-6,500

Typical onset: 70,000-120,000 mi

Symptoms: Transmission fluid leaking at radiator connections or lines, Transmission overheating, burnt smell, Pink or red fluid under vehicle at front, Transmission slipping after radiator work or coolant contamination

Fix: Steel cooler lines rust through at bends or fittings; cooler inside radiator can crack allowing coolant/ATF mixing (catastrophic for transmission). Replace both lines and install external auxiliary cooler as preventive (3-4 hours). If coolant mixed into trans, requires full transmission rebuild and radiator replacement (see transmission failure cost).

Estimated cost: $350-650

Typical onset: 80,000-130,000 mi

Symptoms: Clunking from front suspension over bumps, Steering wander, loose or vague steering feel, Uneven tire wear on inside or outside edges, Vibration in steering wheel at highway speed

Fix: Lower control arms use pressed-in ball joints and bonded rubber bushings that deteriorate. Most shops replace entire control arm assemblies rather than press in components (2.5 hours per side). Also inspect outer tie rod ends and sway bar links while in there. Alignment mandatory after replacement.

Estimated cost: $450-750

Typical onset: 60,000-100,000 mi

Symptoms: Check engine light with P0442 or P0455 (EVAP leak codes), Fuel smell near rear of vehicle, especially when filling tank, Difficulty filling tank, nozzle clicks off repeatedly, Visible rust or holes in fuel filler neck tube

Fix: Filler neck rusts from inside out in salt states, canister vent valve sticks. Smoke test required for diagnosis (0.5 hours). Filler neck replacement is 2 hours, canister or vent valve is 1.5 hours. Recall 00V176000 covered some fuel system issues but not all EVAP components.

Estimated cost: $250-550

Symptoms: Door opens or closes partially then stops, error chime sounds, Door won't latch closed or latch won't release, Motor runs but door doesn't move, Door operates manually but not with power button

Fix: Complex system with motors, cables, rollers, latches, and control modules. Cables stretch or fray (2-3 hours per door), latch mechanisms bind (1.5 hours), rollers wear causing binding (1 hour). Diagnosis critical as parts are expensive. Many owners disable power function and use manually to avoid repair cost.

Estimated cost: $300-900
