The 1982 AMC Spirit is a compact based on the Gremlin platform with typical AMC rust issues and aging drivetrain components. The 258ci I6 is bulletproof if maintained, but automatics are fragile and rust attacks every structural point.
Torque-Command (Chrysler 904/998) Automatic Transmission Failure
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: Slipping between 2nd and 3rd gear under load, Delayed engagement from park to drive (2+ seconds), Burnt transmission fluid smell and dark red/brown color, Leaking from front pump seal or cooler lines
Fix: Full rebuild required including clutch packs, bands, and seals. 8-12 hours labor. Cooler lines and transmission mount typically replaced simultaneously since they're accessible.
Estimated cost: $1,800-2,800
Engine Lower End Bearing Failure (258ci I6)
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Deep knocking sound from crankcase, worse when cold, Falling oil pressure at idle (below 10 psi hot), Metal shavings visible in oil filter media, Sudden catastrophic failure if ignored
Fix: Requires crankshaft removal, main bearing replacement, rod bearing inspection. Often triggers full rebuild since engine is apart. 16-24 hours labor for proper job including machine work.
Estimated cost: $2,200-3,800
Structural Floor Pan and Frame Rail Rust
Common · high severitySymptoms: Visible rust perforation behind rear wheels and rocker panels, Soft or crumbling metal in jack points, Transmission crossmember mount points rotted through, Rear shock towers separating from body
Fix: Requires panel replacement with welding. Transmission mounts fail because crossmember rusts out. Real fix is 12-20 hours metalwork depending on extent. Patch jobs last 1-2 years in salt states.
Estimated cost: $1,500-4,000
Carburetor Issues (Carter BBD 2-barrel)
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Hard starting when hot, needs extended cranking, Rough idle below 600 rpm, stalling at stop signs, Hesitation on acceleration from stop, Black smoke and fuel smell indicating rich condition
Fix: Rebuild kit and full cleaning usually sufficient. Choke pulloff and accelerator pump most common culprits. 2-4 hours including adjustment time.
Estimated cost: $300-600
Fuel System Vapor Lock and Delivery Issues
Occasional · medium severitySymptoms: Stalling in hot weather after highway driving, Won't restart for 20-30 minutes after heat soak, Fuel smell in engine bay on hot days, Fuel filter restriction causing lean condition
Fix: Replace rubber fuel lines (they're 40+ years old), add heat shield to fuel line near exhaust manifold, replace fuel filter. Mechanical fuel pump may need replacement. 2-3 hours labor.
Estimated cost: $250-500
Front Suspension Component Wear
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Wandering steering requiring constant correction, Clunking over bumps from worn ball joints, Uneven tire wear on inside edges, Shimmy at highway speeds
Fix: Upper and lower ball joints, tie rod ends, and idler arm commonly worn. All should be replaced as a set with alignment. 4-6 hours labor.
Estimated cost: $600-1,100
