Should I change Trasmission Fluid

[jterek]

I have a 2007 Impala with about 56,000 miles on it. I have a job where I drive a ton on a daily basis. How often should I be changing my transmission fluid, and coolant?

if you have your manual it should state how often to change it in there. i think its like every 50,000.

I would say 50K but a lot of people will tell you not to ever change it.
