Getting my Tranni fluid checked at dealership - please help

I took my 2017 TRD Sport to the Dealer to have them manually check the fluid level, which is done by checking the overflow hole. I'm not sure they actually did this, but the paperwork did not the level was good.

I think the 2016's are more prone to having the issue being low on trans fluid compared to the 2017 models.

 

after reading ALL the threads and discrepancies (just in this thread alone) I'm leaving mine alone - I am not experiencing any delayed shifting or lag from reverse to forward. I believe it has a 6 year 60,000 wrnty on the tranni so I will let Toyota play this out - I already have a case # and am documented with Toyota just in case. My rear diff. is on the recall but not leaking. - I plan on getting that done when I get the notice in the mail
