The 1997 Dodge Ram Van is a workhorse built on Chrysler's B-series platform with durable drivetrains but notorious for transmission issues and cooling-related engine damage. The 5.2L and 5.9L V8s are generally reliable when maintained, but the 46RE/47RH transmission is the Achilles' heel.
Automatic Transmission Failure (46RE/47RH)
Common · high severityTypical onset: 120,000-180,000 mi
Symptoms: harsh or delayed 2-3 shift, slipping under load, no overdrive or stuck in 2nd gear, metal shavings in pan during service
Fix: Complete rebuild required in most cases, 12-16 hours labor. Input and output shaft bearings often show wear before total failure. Band adjustment and fluid changes can delay but rarely prevent eventual rebuild.
Estimated cost: $2,200-3,800
Transmission Oil Cooler Line Failure
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: transmission fluid leaking near radiator, pink or milky transmission fluid, overheating transmission, sudden loss of forward gears after coolant contamination
Fix: Steel lines rust through where they pass under the engine or at radiator connections. If coolant mixes with ATF, both transmission and radiator may need replacement. Lines alone: 2-3 hours. Full contamination repair: 14-18 hours with flush and rebuild.
Estimated cost: $150-400 (lines only), $3,500-5,500 (if contamination damaged transmission)
Head Gasket Failure (5.2L/5.9L V8)
Occasional · high severityTypical onset: 150,000-200,000 mi
Symptoms: white smoke from exhaust, coolant loss with no external leaks, milky oil, overheating, rough idle when warm
Fix: Chrysler Magnum V8s blow head gaskets when overheated or neglected. Requires both heads pulled, machined if warped, new gaskets and bolts. Often find cracked heads on passenger side. 14-18 hours labor. Always check for cracked heads before reassembly.
Estimated cost: $1,800-3,200
Transmission Mount Collapse
Common · medium severityTypical onset: 60,000-120,000 mi
Symptoms: heavy clunk when shifting into drive or reverse, vibration at idle in gear, visible transmission sag when inspected from below
Fix: Rubber mount deteriorates and transmission drops, stressing cooler lines and causing harsh shifts. Simple fix: 1.5-2 hours with transmission slightly supported. Replace while doing any transmission work.
Estimated cost: $180-320
Intake Manifold Plenum Gasket Leak (5.2L/5.9L)
Occasional · medium severityTypical onset: 100,000-160,000 mi
Symptoms: rough idle, loss of power, lean codes (P0171/P0174), whistling sound from engine bay under acceleration
Fix: Plenum gasket cracks and leaks vacuum. Common on Magnum engines. Upper intake must be removed, 3-4 hours labor. Use upgraded composite gasket, not original paper style.
Estimated cost: $350-650
Freeze Plug Failure
Occasional · medium severityTypical onset: 120,000-180,000 mi
Symptoms: coolant dripping from engine block sides or rear, coolant loss without visible external leak, overheating if leak is severe
Fix: Rusted freeze plugs leak or pop out, common on rear of block behind transmission. Rear plugs require transmission removal: 10-14 hours. Side plugs accessible with engine mounts loosened: 4-6 hours. Many shops quote 'all freeze plugs' when one goes since labor is intensive.
Estimated cost: $400-800 (side plugs), $1,200-2,200 (rear plugs with trans removal)
Fuel Filter Clogging and Pump Failure
Occasional · medium severitySymptoms: hard starting after sitting, loss of power uphill or under load, stalling at idle after highway driving, long crank before starting
Fix: Inline fuel filter clogs if neglected (should be changed every 30k but rarely is). In-tank pump fails from running dirty fuel or overheating. Filter: 0.5 hour. Pump requires dropping tank: 2.5-3.5 hours in a van (tight access).
Estimated cost: $60-120 (filter), $450-750 (pump)
Solid cargo platform if the transmission has been rebuilt or is under 100k with documented fluid changes — otherwise, budget $3k for a trans job within the first year.
