2007 CHRYSLER PACIFICA

Typical onset: 70,000-110,000 mi

Symptoms: Transmission slipping or erratic shifts, Pink or milky fluid in transmission pan (coolant mixing with ATF), Transmission overheating warnings, Strawberry milkshake appearance in coolant reservoir

Fix: The internal transmission oil cooler (inside the radiator) fails and allows coolant to mix with ATF, destroying the transmission. Requires radiator replacement, transmission flush or full rebuild depending on contamination extent. If caught early: 3-4 hours for cooler/radiator and flush. If trans is damaged: 12-16 hours for rebuild or replacement.

Estimated cost: $800-1,200 if caught early, $3,500-5,500 with transmission rebuild

Typical onset: 80,000-140,000 mi

Symptoms: Sudden loss of compression in one or more cylinders, Severe misfires and rough running, Metallic rattling from engine, Check engine light with multiple misfire codes, Complete engine failure without warning

Fix: The 4.0L V6 has a known defect where valve seats separate from the cylinder head, dropping into the cylinder and causing catastrophic damage to pistons, rings, cylinder walls, and crankshaft. Requires complete engine rebuild or replacement. 24-32 hours labor for removal, rebuild/replace, and reinstall.

Estimated cost: $4,500-7,500 for used engine swap, $6,000-9,000 for rebuild

Typical onset: 60,000-100,000 mi

Symptoms: Heavy clunk when shifting from park to drive or reverse, Excessive vibration at idle, Visible engine/trans movement when accelerating, Transmission hitting crossmember on hard acceleration

Fix: The rubber transmission mounts deteriorate and collapse, especially the rear mount. Replacement requires supporting the transmission and removing the old mount. 2-3 hours labor for rear mount, add 1 hour if doing both mounts.

Estimated cost: $350-600

Typical onset: 90,000-130,000 mi

Symptoms: Extended cranking before engine starts, Hesitation or stumbling under acceleration, Loss of power on highway, Fuel pump whining noise from tank area

Fix: The in-tank fuel filter/pump sock clogs with sediment, restricting fuel flow. Often requires fuel pump module replacement as filter is not separately serviceable. Tank must be dropped. 3-4 hours labor.

Estimated cost: $650-950

Typical onset: 100,000-150,000 mi

Symptoms: External coolant leaks from head/block junction, White smoke from exhaust, Coolant loss with no visible external leak, Bubbles in coolant reservoir, Overheating under load

Fix: Both 3.5L and 4.0L V6 engines can develop head gasket failures, though less catastrophic than dropped valve seats. Requires removal of both heads, machining if warped, new gaskets and bolts. 14-18 hours labor for both banks.

Estimated cost: $2,800-4,200

Typical onset: 120,000-180,000 mi

Symptoms: Blue smoke on startup or acceleration, Excessive oil consumption (1 quart per 1,000 miles or worse), Fouled spark plugs, Loss of power and compression

Fix: The 3.5L develops piston ring wear leading to oil burning. Minor cases can be managed with frequent oil changes, but severe cases require engine rebuild with new pistons and rings. 20-26 hours for complete rebuild.

Estimated cost: $4,000-6,500 for rebuild
