Detailed Description

Part number 642 is a TC Remanufacturing automatic transmission torque converter for select Dodge Dakota, Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500, and Dodge Ram 1500 Van applications, along with several B-, D-, and W-series trucks and the Ramcharger. The lock-up design helps maintain efficient drivetrain operation in the listed vehicles, while the 11-inch diameter, 23-spline configuration, 1.810 pilot diameter, and 130-tooth wide ring gear support proper transmission interface where specified.

This torque converter uses a slotted hub, 4 pads offset mounting, and a 10.000 bolt circle with 5/16 x 24 mounting threads. The 2300-2600 stall range and high-carbon friction construction make it a direct-spec replacement for the identified converter codes 642, 643, and 878.

What It Helps Address

• Transmission shudder during lock-up engagement
• Slipping or inconsistent torque transfer
• Incorrect stall characteristics from a worn converter
• Vibration or drivability issues tied to converter wear
• Fitment problems when replacing a converter with the wrong code

Installation Notes and Tips

Verify the converter code, spline count, pilot diameter, bolt circle, and ring gear tooth count before installation. Confirm the transmission and engine combination on your Dodge Ram, Dakota, or van application matches the listed fitment, and inspect the flexplate, seals, and transmission fluid condition during service. Proper converter seating and alignment are critical before bolting the unit in place.

Quality Assurance

TC Remanufacturing supplies remanufactured drivetrain components for transmission service, and this converter is built to the listed specifications for the confirmed applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
