Your transmission was made before the engineers department had to be sent to rehab.

The most complex systems can fail in the simplest way.

i don't believe in the lord! He's never bought me a Mercedes Benz.

I'm all for being "prepared" for a road trip, but taking a spare transmission with you seems a bit silly.

Unless you have a strong reason to believe your current transmission is on its way out (slipping, flaring, long gear engagement)....I wouldn't bother.
