IF it smells bad it probably is....burnt.. A trans flush will be required !
Generally if the trans temp light has come on the fluid has overheated and the friction modifiers are weakened or known as toast LOL.
If you plan on doing the PML pan route, what you could do in the meantime is suction out as much fluid through the dipstick tube, and get some fresh ATF+4 in there.
Once the Pan arrives do the dealer flush & install PML pan then.
