205 seems a tad high for a transaxle under minimal load, but maybe it's absorbing heat from the engine.
I had a transmission temp gauge in my Ford F250 Super Duty pickup as part of the trailer towing package. On a highway without any trailer load it would show 190 and just sit there. Towing Pearl on her single car trailer it would rise up to 191-192, that's it. If I was pulling the car club's "LeMons" Honda in their enclosed trailer it would sit at 192-193.
Granted, that truck had bigger cooling for the engine and transmission included in the towing package, but it never went over 193, even pulling long uphills in North Carolina and Georgia.
