A mechanic advised me to change the transmission fluid whenever I changed 
the engine oil, even tho the fluid doesn't show wear as the oil does. Since 
I like to change the engine oil a little too frequently, sometime after 100 
hours and never longer than 150 hours, I chose to change the transmission 
fluid every other time.
