A 2006 Dodge Ram 3500 likely uses
ATF+4 transmission fluid if it has a 4-speed automatic transmission (46RH or 47RE). However, some 2006 models might have a 5-speed automatic (48RE) which *could* also use ATF+4, but checking your owner's manual is crucial. The manual will definitively state the correct fluid type.
Do not rely solely on this information. Always consult your owner's manual for the specific transmission fluid recommendation for your exact vehicle. The year and specific trim level can impact the type of transmission and, therefore, the required fluid.
