I was a new mechanic at a local Volvo dealership about 15 years or so ago, no experience at all anywhere other than my own shop at home. About 3 months into this gig, I get my first front wheel drive tranny r&r. I struggled for several hours trying to get this thing out. I had never really dealt with the large number of wires, sensors, etc on these computer cars. I pack up for the day thinking I had it made in the morning, button up the subframe, reinstall strut assembly, etc.
IT ABSOLUTELY SUCKED when I walked and unlocked my toolbox, to find the flywheel laying under the jacket I had thrown in the top of my tool box earlier the day before. Needless to say, I was ridden like a donkey for days to come for that.
