1990 TOYOTA CRESSIDA

Typical onset: 100,000-150,000 mi

Symptoms: Pink or strawberry milkshake-colored transmission fluid, Transmission slipping or delayed engagement, Coolant level dropping without external leaks, Transmission failure within days of fluid contamination

Fix: The internal ATF cooler in the radiator fails, allowing coolant and transmission fluid to mix. Requires radiator replacement, complete transmission flush (often multiple flushes), new ATF, and sometimes full transmission rebuild if contamination caused internal damage. Preventive radiator replacement is 2-3 hours labor; post-failure with trans damage is 12-18 hours total. This is THE killer of A340E automatics.

Estimated cost: $800-1,200 preventive radiator replacement; $3,500-5,500 if transmission rebuild needed after contamination

Typical onset: 120,000-180,000 mi

Symptoms: White smoke from exhaust on startup, Coolant consumption without visible leaks, Overheating under load, Milky oil or oil in coolant reservoir, Rough idle or misfires

Fix: The 7M-GE shares the 7M-GTE's tendency toward head gasket failure, though less severe without turbo heat. Job requires cylinder head removal, resurfacing (almost always warped .003-.008 inches), new head gasket set, head bolts (reuse causes repeat failures), timing belt, water pump, and all seals. Competent tech needs 12-16 hours. Machine shop resurface adds 2-3 days turnaround. Use OEM Toyota gasket and ARP studs if keeping long-term.

Estimated cost: $2,200-3,800

Typical onset: 100,000-160,000 mi

Symptoms: Visible rubber separation between outer ring and hub, Vibration at idle that worsens with RPM, Serpentine belt tracking issues or squealing, Timing marks no longer aligned properly

Fix: The rubber bonding layer degrades and the outer ring separates or spins freely. Can cause timing issues and accessories belt problems. Replacement requires balancer puller and installer tools; shade-tree mechanics often damage the new one during install. 2-3 hours labor. Always replace when doing timing belt service at this age.

Estimated cost: $350-600

Typical onset: 80,000-120,000 mi

Symptoms: Clunk when shifting from reverse to drive, Excessive driveline vibration at idle in gear, Visible sagging or torn rubber on mount, Harsh engagement into gear

Fix: Rear transmission mount deteriorates and causes harsh shifting feel and driveline movement. Simple replacement, 1-1.5 hours labor. Often done alongside engine mounts which fail on similar schedule. Cheap insurance for drivability.

Estimated cost: $180-320

Typical onset: 150,000+ mi

Symptoms: Hesitation or stumble under acceleration, Hard starting when hot, Loss of power at highway speeds, Fuel pump whine audible from rear seat area

Fix: In-tank fuel pump and external inline fuel filter both wear. Filter should be replaced every 30k but rarely is on used examples. Clogged filter starves pump and accelerates its failure. Pump replacement requires dropping tank, 3-4 hours labor. Always replace filter first ($20 part, 0.5 hours) before condemning pump.

Estimated cost: $80-150 for filter; $450-750 for pump replacement

Symptoms: Ticking or tapping from valve cover that doesn't quiet after warmup, Loss of power and poor fuel economy, Metal shavings in oil, Valvetrain noise that worsens over time

Fix: The 7M-GE is extremely durable with proper oil changes, but neglect causes cam lobe and lifter wear. Requires cylinder head removal, camshaft replacement, all 12 lifters, and often valve stem seals while apart. 14-18 hours labor. Usually only seen on severely neglected examples with 10k+ mile oil change intervals or low oil operation.

Estimated cost: $2,800-4,200
