2000 LEXUS IS 300

Typical onset: 60,000-120,000 mi

Symptoms: Grinding or whining noises in 2nd or 3rd gear, Difficulty engaging gears or gear pop-out, Fluid leaking from bellhousing area, Complete loss of drive if case cracks catastrophically

Fix: W55 5-speed is weak behind the 2JZ. Case cracks at the countershaft bore. Requires transmission removal, typically replacement with used unit or upgraded W58/CD009 swap. 8-12 hours labor for R&R, plus alignment and clutch while you're in there.

Estimated cost: $2,000-4,500

Typical onset: 150,000-250,000 mi

Symptoms: Knocking or ticking from bottom end, worse on cold start, Low oil pressure at idle when hot, Metal shavings in oil or filter, Sudden catastrophic failure if bearing spins

Fix: 2JZ-GE is tough, but extended oil change intervals or sludge buildup can starve bearings. Requires engine removal, full teardown, crank inspection/machining, new bearings, honing, reassembly. 20-30 hours labor. Often combined with rings, seals, timing components.

Estimated cost: $4,000-7,000

Typical onset: 120,000-180,000 mi

Symptoms: White smoke from exhaust on startup, Coolant consumption without visible leaks, Overheating or erratic temp gauge, Milky oil or bubbles in coolant reservoir

Fix: 2JZ head gaskets can fail from age, overheating, or poor coolant maintenance. Head removal, resurfacing, ARP studs recommended, new timing belt/water pump while apart. 12-16 hours labor.

Estimated cost: $2,500-4,000

Typical onset: 100,000+ mi

Symptoms: ATF puddle under front of car, Transmission slipping or delayed engagement when fluid low, Burnt ATF smell, Low fluid on dipstick

Fix: Hard lines and rubber hoses corrode or crack at the cooler and radiator connections. Replace lines and hoses, refill and flush ATF. 2-3 hours labor if caught early.

Estimated cost: $300-700

Typical onset: 80,000-150,000 mi

Symptoms: Clunking on acceleration or deceleration, Excessive driveline vibration, Shifter slop or vague engagement (manual), Visible cracking or separation in rubber

Fix: Rubber mount collapses, allowing excessive drivetrain movement. Replace transmission mount and inspect engine mounts. 1.5-2 hours labor.

Estimated cost: $200-400

Typical onset: 100,000+ mi

Symptoms: Hard starting or long crank time, Loss of power under load or at highway speed, Surging or hesitation, Check engine light with lean codes

Fix: In-tank filter screen clogs with sediment, or external filter (if equipped) restricts flow. Drop tank, replace pump assembly or clean pickup screen. 3-4 hours labor.

Estimated cost: $400-900

Typical onset: 120,000+ mi

Symptoms: Check engine light with P1349 VVT code, Rough idle or stumble on startup, Rattling noise from timing cover area, Reduced power and fuel economy

Fix: VVT-i cam gear can slip internally. Remove valve cover and timing cover, replace actuator gear. Do timing belt, water pump, seals at same time. 8-10 hours labor.

Estimated cost: $1,200-2,000
