I recently bought a used Trek that has Deore LX 9 speed shift levers. The right lever that controls the rear derailleur is reverse from my Cannondale and the Trek left front derailleur lever (The Cannondale levers are the same).
On the Trek the upper trigger you pull causes the rear derailleur to down-shift to a lower gear and the lower trigger you push causes the rear derailleur to up-shift to a higher gear. How do you reverse them?

I suspect that your Trek probably has a RAPID RISE (reverse pull) rear derailleur ... that's considered to be 'a good thing' because the reverse pull expedites downshifting to lower gears ...
If the change in the derailleur's direction from what you are familiar with when you are shifting bothers you, then you'll need to change the rear derailleur to a "normal" pull rear derailleur.
If your derailleur is a normal pull rear derailleur, then you'll have to buy an older shifter.
