* Automatic Transmission: Most likely, you cannot fill the transmission fluid yourself. Automatic transmissions on the 2002 Ram 1500 typically require a specialized procedure using a fluid exchanger. There's no readily accessible fill port like an engine oil fill cap. Attempting to add fluid through a wrong method could damage the transmission. You should take your vehicle to a qualified mechanic or transmission specialist for transmission fluid service.
* Manual Transmission: If your Ram 1500 has a manual transmission, the fill location will be on the transmission itself. Look for a fill plug, usually a bolt-like fitting, on the top or side of the transmission case. Consult your owner's manual for the exact location and procedure.
In short: For an automatic transmission, take it to a professional. For a manual transmission, check your owner's manual.
