What kind of transmission does my 2004 crown Victoria have?

This vehicle was equipped with either a 4R70W automatic transmission or a 4R75W automatic transmission. The certification label on the driver's door jamb area will indicate a code under "TR" to identify it. "H" stands for 4R70W built in the Sharonville transmission plant, "R" indicates a 4R75W built at the Livonia transmission plant and "U" says it's a 4R70W built at the Livonia transmission plant. Check your fluid level to ensure it is full and that the fluid is clean.
