Why do you have to remove the subframe to change the transmission filter?

Some vehicles require dropping the subframe or cross member just to remove the transmission pan and replace the filter. This turns a routine maintenance job into a difficult, time-consuming struggle, especially when dealing with rust and corrosion.

Looking to have my transmission fluid and filter changed. There is a cross member? That has to be moved in order to remove the pan to change the filter.source ↗

That Job is bad. Especially if the subframe is rusty / crusty etc. Ive done tons of valve bodies with lead frames and some are cake - most are a legit pain because of rust / corrosion etc.source ↗
