Illustration Quality:
High-quality, detailed line drawings and exploded views of every major component and sub-assembly.
Depth Of Coverage:
Highly detailed, focusing on OEM part numbers, diagrams, and application. It is intended for parts counter personnel, technicians, and knowledgeable DIYers for identifying and ordering correct replacement parts. Does not typically include diagnostic procedures or step-by-step repair instructions, but provides the foundation for those activities.
Parts Numbering System:
Utilizes the standard Mopar (Chrysler) part numbering system, which is critical for ordering correct replacements.
Standard Transmission Ram1500:
4-speed automatic transmission (42RE/44RE).
Optional Transmission Gasoline:
5-speed manual transmission (NV3500 for V6, NV4500 for V8).
Optional Transmission Diesel:
5-speed manual transmission (NV4500 HD) or 4-speed automatic (47RE).
4X4 System:
Part-time 4WD system with electronic or manual transfer case engagement (e.g., NV235, NV244).
Transmission Fluid Gasoline:
ATF+4 (for automatic transmissions, after an update; older specs might list ATF+3 or Dexron III/Mercon equivalents).
Transmission Fluid Diesel:
ATF+4 for 47RE, NV4500 requires SAE 5W-30 or 10W-30 manual transmission fluid (API GL-4).
Oil Change Interval Gasoline:
Typically every 3,000-7,500 miles or 6-12 months, depending on driving conditions and oil type used (refer to specific service manual for precise recommendations).
Oil Change Interval Diesel:
Cummins Diesel: Every 7,500-15,000 miles or 12 months, with specific recommendations for severe duty.
Transmission Service Interval:
Automatic: Every 30,000-60,000 miles. Manual: Check fluid condition, replace as needed or per severe service schedule.
Coolant Flush Interval:
Every 30,000-60,000 miles or 2-4 years.
Engine Oil Gasoline:
SAE 5W-30 or 10W-30 (API certified, meeting Chrysler MS-6395 specification).
Engine Oil Diesel:
CJ-4 or CK-4 rated Diesel Engine Oil (e.g., 15W-40 for most conditions, consult manual for temperature variations).
Coolant Type:
Ethylene Glycol based antifreeze/coolant, meeting Chrysler MS-9769 or equivalent (typically a 50/50 mix with distilled water).
Brake Fluid Type:
DOT 3 or DOT 4 Brake Fluid.
Power Steering Fluid:
ATF+4 or manufacturer-specified power steering fluid.
Transmission Issues:
Some 45RFE/48RE automatic transmissions can experience solenoid issues or torque converter clutch shudder. Manual transmissions like the NV4500 can have issues with the 5th gear nut loosening.
Engine Issues Gasoline:
Magnum V8s are generally robust, but intake manifold gaskets can be a source of vacuum leaks. Some crankshaft position sensors may fail.
Engine Issues Diesel:
5.9L Cummins is legendary for durability, but early models can have lift pump failures or injector line issues. Fuel heater issues can also occur in cold climates.
Suspension Steering Issues:
Ball joints, tie rod ends, and steering box wear are common on higher mileage trucks due to load and use. Leaf spring issues, especially with heavy loads, can occur.
Electrical Issues:
Clock spring in the steering column, body control module (BCM) issues, and intermittent lighting problems can be encountered.
Rust Corrosion:
Common in rust-belt regions, particularly affecting rocker panels, cab corners, bed floor, and frame components.
