trans temp should be just over 100* & check plug is a 5mm allen in the bottom of pan; this is also where it is filled.
19mm plug at rear is your drain plug.
You fill the transmission into the smaller port & allow excess to drain out until it slows to a steady drip-then install the 5mm allen plug.
It's designed to be overfilled & allowed to drain to correct level.
Plan on buying a case of fluid to do in correct.
You're probably gonna see some dirty fluid come out on first drain.
