I change mine after every race event. For me this includes one practice day & the race day itself. I use Motul Transoil 10W30. I believe that changing it that frequently is “cheap insurance”…

I’ve heard the ATF is a little too thin and doesn’t have enough or the right kind of high pressure lubricants to withstand the transmission and clutch.

My engine builder, SwedeTech, highly recommends the Motul Transoil but doesn’t recommend ATF. They rebuild these engines every day and see the gearbox & clutch internals so I trust their judgement.
