Yeah I found no plug. I had my Wife watch as I turned the motor. I just dropped the pan, replaced the filter and filled er back up. It wasn't that my fluid was dark, burnt or anything, it was in good shape I just wanted to has a base line on all the fluids in the new to me truck. I am still working on it all though, and to be honest I havent found anything odd or in need of it yet.... although my driveway does have a big stain from the ATF. Big as in about 2x2. I need to be more careful the HOA is all up on my about stuff like the stains and all my "Toys"
As for others doing work, I am the same way. I cant stand others even driving my stuff!
