1998 DODGE RAM VAN

Typical onset: 90,000-150,000 mi

Symptoms: Delayed or harsh 2-3 upshift, especially when warm, Slipping under load or complete loss of forward gears, Whining from torque converter or internal bearings, Metal shavings in pan during fluid service

Fix: These transmissions eat overdrive clutches and governor pressure solenoids. Full rebuild with updated clutch packs, solenoid body, and input/output bearings is standard. Expect 12-16 hours labor for R&R and rebuild. Transmission cooler replacement mandatory during rebuild to prevent repeat failure.

Estimated cost: $2,200-3,800

Typical onset: 80,000-120,000 mi

Symptoms: Rough idle with P0171/P0174 lean codes, Loss of power on acceleration, Audible hissing from intake area, Oil consumption increases as gasket deteriorates

Fix: The composite plenum gasket cracks and creates vacuum leaks. Requires upper intake removal, gasket replacement with upgraded aluminum gasket kit, and throttle body cleaning. Budget 4-5 hours labor. Often reveals cracked plenum pan that needs replacement too.

Estimated cost: $450-750

Typical onset: 150,000-200,000 mi

Symptoms: Blue smoke on startup or acceleration, Oil consumption 1+ quart per 1,000 miles, Loss of compression and power, Fouled spark plugs on specific cylinders

Fix: High-mileage Magnums burn oil through worn rings or valve seals. Full teardown for rings, honing, valve job, and freeze plugs if coolant-contaminated. Reality check: 30-40 hours for complete overhaul. Most owners opt for junkyard engine swap instead at 15-20 hours labor.

Estimated cost: $3,500-6,500

Symptoms: Coolant loss with no external leaks, White smoke from exhaust, Milky oil or coolant in oil, Overheating with good thermostat and water pump

Fix: Usually follows cooling system neglect or failed water pump. Requires both heads pulled, resurface, new gaskets, and timing chain inspection. Critical: check for cracked heads before reassembly. Budget 12-16 hours labor. If heads are warped beyond spec, add $400-600 for new castings.

Estimated cost: $1,800-2,800

Typical onset: 80,000-140,000 mi

Symptoms: ATF puddles under front of vehicle, Low transmission fluid warnings or burnt smell, Lines rusted through at frame brackets, Drips visible along passenger side frame rail

Fix: Steel cooler lines rust from road salt and moisture. Replace both lines from transmission to radiator-mounted cooler. Use pre-bent steel or upgrade to braided stainless. Add auxiliary cooler if towing. 2-3 hours labor with proper flare tools.

Estimated cost: $300-550

Typical onset: 100,000-150,000 mi

Symptoms: No-start or extended cranking when hot, Stalling under acceleration or at highway speed, Fuel pressure drops below 45 psi, Pump whine audible from rear

Fix: In-tank pump fails from contaminated fuel or age. Midship fuel tank requires chassis access, not cab removal on vans. Replace pump, strainer, and inline filter together. 3-4 hours labor fighting rusty straps and filler neck.

Estimated cost: $450-700

Typical onset: 80,000-120,000 mi

Symptoms: Clunking over bumps from front end, Wandering or loose steering feel, Uneven tire wear on inside edges, Play in wheel when jacked up

Fix: Heavy van weight destroys ball joints and control arm bushings. Replace uppers and lowers together with alignment. OEM Moog or equivalent required for longevity. 4-6 hours labor for both sides with proper ball joint press.

Estimated cost: $600-950
