* Auto parts stores: Major chains like AutoZone, Advance Auto Parts, NAPA Auto Parts, and O'Reilly Auto Parts all carry transmission fluid. Be sure to specify the type of transmission your Charger has (automatic or manual) and the exact fluid type recommended in your owner's manual.
* Dealerships: Dodge dealerships will have the correct fluid, but it will likely be the most expensive option.
* Online retailers: Amazon, eBay, and other online retailers sell transmission fluid. Again, be absolutely certain to get the correct fluid type.
Crucially: Do not just buy any transmission fluid. Your 2006 Dodge Charger's owner's manual will specify the exact type and amount of transmission fluid required. Using the incorrect fluid can severely damage your transmission. Check your owner's manual before purchasing anything. The manual will tell you the correct fluid type (e.g., ATF+4, Mercon V, etc.).
Buying the correct fluid is paramount to avoiding costly transmission repairs. If you are unsure, consult your owner's manual or a qualified mechanic.
