It's a common fault on is220d manual box that's y Lexus stop doing manual,I get that on mine which is 2006 but now I'm used to it when dmf gets warm thats when it plates up,when I got my car last yr 2nd gear used to pop out got complete box replaced under warranty did ask about clutch/dmf said it ok mines done 85k had box at 76k hope this helps @ good luck
