Automatic transmission RWD 5.7 HEMI P04800740AC DODGE CHARGER 32TKM
at Buy Mustang parts Ltd, the part number P04800740AC is a premium mechanical asset. It represents the 8-speed automatic transmission for the 2015+ Dodge Charger/Challenger R/T with the 5.7L HEMI V8.
While many 5.7L HEMI models used the 5-speed NAG1 in earlier years, this specific part number confirms the transition to the far more advanced ZF 8HP70 (TorqueFlite 8). At only 32,000 km (32TKM), this is effectively a “like-new” unit in the luxury spare parts market.

2. Why “P04800740AC” is a High-Value Inventory Item
-
Fuel Economy & Performance: This 8-speed improved the Charger R/T’s fuel economy by 11% while dropping 0–100 km/h times. Owners of older Chargers often look for these units for “restomod” swaps.
-
Low Mileage (32k km): At this distance, the factory clutch packs and solenoids are in peak condition. This unit has not even reached its first recommended fluid service interval (which is 80k–100k km).
-
Interchangeability: This part number is a direct fit for the 2015–2018 Dodge Charger R/T and Challenger R/T (RWD only).
