question about automatic trans service

I have a 07 cobalt LT auto and have approx 36,400 miles on it. Should I get the transmission service done on it? Ive heard different mileages about when it should be changed/flushed. What mileage does gm recommend to have it done at?

50k miles. dexron vi compatible fluid

GM does not recommend a fluid change under normal service conditions.

That being said, I agree with the other guy replying about a fluid and filter change and 50k miles.

if you don't service your transmission at regular intervals it will fail prematurely and will need a rebuild/replacement. ever notice on an older car how you see brown trans fluid and the thing starts shifting all weird? that's clutch dust in the fluid. the tranny is now relying on the abnormally thick viscocity of the fluid. that's how you know not to change the fluid and wait it out til you can afford a rebuild. this is just from my experience. of course, gm wants you to bring you their blown tranny way over warranty so you can pay full price to have it fixed. sometimes common sense can outsmart manufacturers specs.

So basically it is best then to get it done at 50,000 miles? The dealerships over here said they recommend getting it done at 30k miles. Would you say that is kinda early to have it done?

30k is about right. 50k is even stretching it a little.
