My co-worker took her car to the local service station to get an oil change and see what else she might need. She had 46K on her car and they recommended a transmission fluid change (automatic) . I told her to go for it since she had a decent amount of miles on the car and she had never done it. I would rather change fluid more often than replace a tranny. She tells me the next day that her boyfriend thinks I am an idiot and that she did not need to change her transmission fluid until 100K. I just said he can go right ahead and do that. My questions is, that with car makes recommended oil changes at 10-15K now are some of the other intervals changing? Have oils gotten that good that the mileage intervals are going up of is this an automotive engineering feet? How often do you change your fluids?

This whole situation just got me thinking about some of these things.
