My profession is mechanical, though not on autos any longer. I am transitioning while working in appliance repair. The only issue so far has been in regards to muscle mass loss. I have to work smarter to get some of the heavier appliances to move when pulling them out, but overall...it is no big deal. I have several sisters who drive big rigs, have 1 that works for the DOT and another that is an engineer for water facilities.
We can do whatever job we want, just like any other woman out there!
