When Should I Flush the Trans Again??

So its been almost two years since I flushed my transmission and did my brakes. I'm probably going to drive an hr and half away to get my pads changed for free, since I have a lifetime pad warranty. Recently I changed my coolant fluid, I was going to change my fuel filter but they wouldn't do it. They said that they can get really stuck on due to dirt and other stuff built up, that they might pinch the line and have to replace the whole line! I couldn't change it after spending hrs pulling on it.

Anyways, I had my trans flushed two yrs ago with full synthetic but they said I should change it every 30xxx miles from now on. My gears now shift pretty good, but feel like they'res a slight resistent. I asked other shops and some say that GM trans are all full synthetic. Again anyways whats your guys thoughts on the fluid and what place to get it changed at?

Every 2 years is fine especially with full synthetic every 30,000 is just stupid they are saying that to rob you. If you have always done it 2 years intervals continue to do so. The resistance could be cause if wrong oil used they may have used a heavier fluid since all fluid is not the same

An average driver drives their car 12k miles a year. By your suggestion he would be changing it at 24k. I periodically check the fluid color and viscosity on my autos. Roughly around 50k unless something is suspect I will change.

You know where I should look to see if I check fluid.

If your cobalt doesnt have a trans dip stick, you can get to the drain bolt to the transmission and get a few droplets to take a look. I believe ours is Dexron IV or V, should be either red, but slightly brown is ok.

Not to bunny-trail, but for your fuel filter, one side has pinch tabs and the other you need a disconnect tool. It'll set you back about $5 and is well worth it!

Not always that easy, my fuel filter took me 45mins to change. That was on a hoist with 2 different fuel line disconnect tools. The dirt is what held mine in there.
