Automatic transmission 5.7 HEMI 4×4 8HP-70 DODGE RAM 1500 37TKM

at Buy Mustang parts Ltd, a ZF 8HP70 (4×4) from a Dodge Ram 1500 with only 37,000 km is a high-value commercial and performance asset. This transmission is the “workhorse” of the Ram lineup, specifically mated to the 5.7L HEMI to handle towing and off-road torque.

1. Technical Identification

While the 8HP70 is used across the Dodge/Ram lineup, the Ram 1500 4×4 version has a specific tail housing designed to mate with the transfer case.

• Model: ZF 8HP70 (TorqueFlite 8)

• Part Number (Common ID): #P68246401AA or #P68213144AB (Verify against the sticker on the casing).

• Configuration: 4×4 / AWD.

• Torque Rating: 700 Nm (516 lb-ft).

• Key Distinction: Unlike the Charger/Challenger version, the Ram version often features a different oil pan (deeper for cooling) and specific TCM (Transmission Control Module) tuning for towing.

2. Premium Condition Report (37TKM)

At 37,000 km, this unit is essentially in “New Old Stock” condition. For your luxury listing, highlight these “Grade A” features:

• Input/Output Shafts: Inspect the splines where the transmission mates to the engine and the transfer case. There should be zero rust or “rounding” of the teeth.

• Fluid Quality: At 37k km, the factory fluid should be pristine. A clean sample is a major selling point for Ram owners who are often wary of “work trucks” that have been abused.

• Mounting Points: Ensure the heavy-duty mounting ears are crack-free—Ram 1500s are often used off-road, and frame-flex can sometimes stress these points.
