I started working on cars when I was 14 removing the starter from a WW II surplus Army Jeep.
I took auto shop in high school rebuilding the engine in a 1949 Ford.
I enlisted in the USAF and was trained as an aircraft mechanic.
My training has allowed me to escape paying $100 of thousands that other people pay to have automobiles.
I have never rebuilt an automatic transmission. Everything else on a car I have done.
