Automatic transmission 2.7 3.5 4-speed Dodge Charger Magnum 04-11 87,000 km

Buy Mustang parts Ltd, the 4-speed automatic for the 2.7L and 3.5L V6 Dodge Charger and Magnum (2004–2011) is the Chrysler 42RLE.

While the 5.7L HEMI models used the robust Mercedes-designed 5-speed (NAG1/W5A580), the V6 models relied on this 4-speed unit. At 87,000 km, this is a prime “low-mileage” unit for the budget-conscious repair market.

1. Technical Identification

• Model: 42RLE

• Type: 4-Speed Automatic (Rear-Wheel Drive)

• Part Numbers (Common IDs): #4800442AA, #4800425AA, #5175415AA.

• Engine Match: Directly compatible with the 2.7L DOHC V6 and 3.5L SOHC V6.

• Historical Context: This transmission is a RWD version of the 42LE transaxle. It was the standard “economy” transmission for the LX platform (Charger, Magnum, 300).

2. Critical “Luxury Grade” Inspection

The 42RLE is notoriously sensitive to maintenance. To sell this as a premium unit from Buy Mustang parts Ltd, verify these specific areas:

1. Solenoid Pack Integrity: The most common failure on these units is the internal solenoid block. In 2026, it is highly recommended to test the solenoid resistance (specifically for codes like P0750 or P0755) before shipping.

2. Input/Output Speed Sensors: These sensors often fail due to heat soak. Replacing them with new OEM Mopar sensors before sale adds significant value and prevents “D.O.A.” returns.

3. The “Limp Mode” Check: Ensure the unit hasn’t been stuck in 2nd gear (Limp Mode), which is often caused by a faulty Valve Body or a shattered separator plate—a known defect in early 42RLEs.

4. Fluid Requirements: This transmission STRICTLY requires ATF+4 (9602 Type). Using generic Dexron or multi-vehicle fluid will cause immediate shuddering and clutch failure.
