1982 PONTIAC PHOENIX

Typical onset: 60,000-100,000 mi

Symptoms: Slipping between gears, especially 1st to 2nd, Delayed engagement when shifting into Drive or Reverse, Metal shavings in fluid, burnt smell, Complete loss of forward gears

Fix: The THM-125 three-speed auto is a weak link in these cars. Internal clutch packs wear prematurely, governor gears crack, and sun gear shells fracture. Rebuild requires 8-12 hours and often reveals damaged hard parts requiring replacement. Many shops prefer swap to remanufactured unit due to internal wear patterns.

Estimated cost: $1,800-3,200

Typical onset: 80,000-120,000 mi

Symptoms: Blue smoke on startup and acceleration, Burning one quart every 500-800 miles, Carbon buildup on spark plugs, Loss of compression in one or more cylinders

Fix: The 2.8L develops chronic oil control ring issues due to inadequate ring tension and cylinder bore wear. Requires complete engine teardown with piston ring replacement at minimum (12-16 hours). Often reveals scored cylinder walls requiring overbore or sleeving. Many engines need complete rebuild with new pistons, bearings, and machine work.

Estimated cost: $2,500-4,800

Typical onset: 50,000-90,000 mi

Symptoms: Severe clunking when shifting into gear, Visible engine movement when accelerating, Vibration at idle that changes with load, Difficulty shifting manual transmission models

Fix: The hydraulic engine and transmission mounts deteriorate rapidly on these transverse FWD setups. Failed mounts allow excessive drivetrain movement that damages CV joints and exhaust components. Replacing both engine and transmission mounts takes 3-4 hours. Critical to use quality replacements as cheap mounts fail within 20,000 miles.

Estimated cost: $350-650

Typical onset: 90,000-140,000 mi

Symptoms: Knocking noise from bottom end that increases with RPM, Low oil pressure warning at idle when hot, Metallic debris in oil filter, Sudden catastrophic engine failure

Fix: The 2.8L V6 suffers premature bearing wear, often from marginal oiling system design combined with neglected oil changes. Once knock develops, damage is done. Requires complete crankshaft removal and inspection (18-24 hours). Crank typically needs grinding, and block often shows bearing saddle damage requiring align-boring. Most shops recommend complete engine replacement or rebuild at this point.

Estimated cost: $3,500-5,500

Symptoms: Hard starting when cold or hot, Rough idle and hesitation, Stalling at stop signs, Poor fuel economy below 18 mpg

Fix: The Rochester E2SE carburetors on these cars are extremely sensitive to fuel quality and age. Varnish clogs small passages, choke pulloffs fail, and mixture control solenoids stick. Thorough rebuild with new kit takes 4-6 hours, plus fuel filter and line cleaning. Modern ethanol fuel accelerates deterioration in stored vehicles.

Estimated cost: $400-750

Typical onset: 70,000-110,000 mi

Symptoms: Rear wheels lock prematurely during braking, Uneven brake wear with rears wearing faster, Poor braking performance in wet conditions, Red brake warning light illuminated

Fix: The X-body platform had notorious brake proportioning issues that led to rear brake lock-up and loss of control. Proportioning valve can stick, sending too much pressure to rear brakes. Replacement takes 2-3 hours including proper bleeding procedure. This was a major recall item on early X-bodies; verify repair was completed.

Estimated cost: $300-550
