The 2008 Dodge Raider is actually a rebadged Mitsubishi Raider, sharing the Dakota platform. The transmission is the Achilles' heel here—expect automatic transmission issues to dominate your ownership experience, particularly with the NAG1 5-speed auto paired to the 4.7L V8.
Automatic Transmission Failure (NAG1 5-Speed)
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: harsh or delayed shifts between 2nd-3rd gear, transmission slipping under load, shuddering during acceleration, check engine light with P0730 or P0700 codes, whining noise from transmission
Fix: The NAG1 (W5A580) transmission suffers from clutch pack wear, valve body issues, and torque converter failure. Full rebuild runs 18-24 hours labor; many shops recommend replacement with reman unit at 12-16 hours. Torque converter alone is 8-10 hours if caught early.
Estimated cost: $2,800-4,500
Transmission Output Shaft Bearing Failure
Occasional · high severityTypical onset: 90,000-130,000 mi
Symptoms: growling or grinding noise that increases with speed, noise changes with load but not with clutch/gear selection, metal shavings in transmission fluid, eventual loss of power transfer to rear wheels
Fix: Output shaft bearing wears prematurely, contaminating transmission fluid with metal. Requires transmission removal and disassembly. Often discovered during transmission rebuild, but catching it early saves the rest of the trans. 10-14 hours labor.
Estimated cost: $1,800-2,800
Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: transmission fluid puddles under vehicle, burnt transmission smell, low fluid level on dipstick, transmission overheating, fluid visible along cooler lines at radiator
Fix: Steel lines rust through at bends and connections, especially in salt states. Lines need replacement, not just patching. 2-3 hours labor for line replacement, but often discovered after transmission damage from running low on fluid.
Estimated cost: $300-600
Torque Converter Clutch Solenoid Failure
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: check engine light with P0740 or P0741, RPM flare on highway without acceleration, poor fuel economy (2-4 mpg drop), shudder at cruise speeds 45-55 mph, transmission stays in lower gear longer than normal
Fix: TCC solenoid sticks or fails, preventing lockup. Can be replaced without full transmission teardown on some units (valve body drop), but access is tight. 4-6 hours labor. Sometimes requires transmission pan removal and valve body work.
Estimated cost: $500-900
Transmission Control Module (TCM) Failure
Occasional · high severityTypical onset: null
Symptoms: transmission stuck in 2nd gear (limp mode), no shifting at all, erratic shifting patterns, multiple transmission codes stored, no communication with TCM on scanner
Fix: TCM mounted on transmission valley gets heat-soaked and fails. Common after transmission work if not properly programmed. Replacement is 2-3 hours including programming. Must be dealer or specialist programmed to VIN. Used TCMs often fail quickly.
Estimated cost: $800-1,400
Neutral Safety Switch Failure
Occasional · medium severityTypical onset: 80,000-120,000 mi
Symptoms: won't start in Park, starts in Neutral, reverse lights don't work, intermittent no-start condition, can shift out of Park without brake depressed, check engine light with range sensor codes
Fix: Switch mounted on transmission side wears internally or gets contaminated with fluid. 1.5-2 hours labor for replacement, includes fluid top-off. Requires external adjustment after installation.
Estimated cost: $250-450
Transmission Mount Deterioration
Common · low severityTypical onset: 60,000-90,000 mi
Symptoms: clunk when shifting from Park to Drive/Reverse, excessive vibration at idle in gear, visible engine/transmission movement when accelerating, drivetrain shudder during throttle tip-in
Fix: Rubber mounts crack and separate, allowing excessive drivetrain movement that accelerates wear on other transmission components. Replace all mounts as a set (engine and trans). 2-3 hours labor.
Estimated cost: $400-700
Hard pass unless you're getting it dirt cheap and can budget $3-4K for an inevitable transmission rebuild—the NAG1 is a ticking time bomb in these trucks.
