Around 1960, my cousin's 1949 Chevy transmission got so hot, there were some welded gears in it.
My Uncle offered to fix it, what he meant was my 16 year old butt was going to fix it, as he was upstairs in his house, watching tv with my Aunt.
I was doing good i thought, until i had to remove that enclosed drive shaft. i went upstairs to grab a soda & ask him how to remove it, he came down stairs &
after he laughed so hard that he had to sit down.
He broke out the Motor Manuals, then told me to wash my hands thoroughly, then he told me to start reading & then he watched me take everything apart.
