DODGE RAM V 1500 TRX 68430191AB Transmission 6.2 2022
part number 68430191AB identifies the TorqueFlite 8HP95 8-speed automatic transmission assembly, specifically calibrated for the 2021–2022 Dodge RAM 1500 TRX equipped with the 6.2L Supercharged HEMI® V8.
This is the “heavy-duty” variant of the ZF 8HP family, designed to handle the $881\text{ Nm}$ ($650\text{ lb-ft}$) of torque and the high-stress demands of a $2,880\text{ kg}$ ($6,350\text{ lb}$) performance truck.
Technical Specifications: 8HP95 (TRX Edition)
| Feature | Specification |
| Torque Capacity | Rated for $approx$ $1,000\text{ Nm}$ ($738\text{ lb-ft}$) |
| Fluid Type | Mopar 8 & 9 Speed ATF (ZF Lifeguard 8 equivalent) |
| Shift Speed | $approx$ $160\text{ milliseconds}$ in Sport/Baja modes |
| Weight | $approx$ $95\text{ kg}$ ($210\text{ lbs}$) dry |
1. Model Year Specifics (2022)
While the 8HP95 is used in several “Hellcat” powered vehicles, the 68430191AB is TRX-specific.
-
Transfer Case Pairing: This unit features a specific tailshaft and output spline count designed to mate with the BorgWarner 44-40 full-time 4WD transfer case.
-
Cooling Circuit: It uses high-flow thermal bypass valves to manage the extreme heat generated during high-speed off-road “desert running.”
-
Software: The internal Transmission Control Module (TCM) is flashed with TRX-specific “Baja Mode” shift points.
2. Critical Components for Inspection
If you are sourcing or selling this specific unit, verify these high-value components:
-
The Torque Converter: The 2022 TRX uses a reinforced, high-stall damper specifically tuned for the 6.2L supercharged pulse.
-
The Oil Pan: This transmission uses a composite plastic oil pan with an integrated filter. Inspect the bottom of the pan for impact cracks; if the truck was “high-centered” off-road, the pan is the first point of failure.
-
Electrical Connector: The 2022 models use a 16-pin high-speed CAN-bus connector. Ensure the plastic locking collar is intact and free of heat-damage from the nearby exhaust.
3. Inventory & Resale Guide
| Inspection Point | What to Look For |
| Output Shaft | Check for “twist” in the splines. Extreme launches can stress the connection to the transfer case. |
| Fluid Condition | The fluid should be a clear “honey” or light green color. If it is dark or smells “burnt,” the internal friction plates have likely overheated. |
| Case Marking | Verify the 8HP95 stamp on the main aluminum housing near the bellhousing. |
Technical Interchange
-
68430191AB vs. 68430191AA: The “AB” suffix indicates a mid-year revision or update (often involving internal seal improvements or software calibrations). The “AB” version is a direct supercession and replacement for the “AA” version.
Professional Installation Tip
When installing a replacement 8HP95, you must perform a “Quick Learn” procedure using a professional scan tool. The transmission needs to synchronize its internal clutch-fill times with the engine’s torque output to prevent “shift shock” or premature clutch wear.
