Checking automatic transmission fluid

[Triedaq]

My son drove a school bus and he was required to do an inspection every day. In addition to all the lights, he was expected to check the fluid levels, including the fluid level in the automatic transmission. I thought that checking the transmission fluid daily was a tad much–weekly or even monthly should have been sufficient. I think my son would have liked a sealed transmission so that he wouldn’t have had to check the transmission fluid level.
