Is it safe to do a transmission flush on your car when you recently changed the filter and fluid? I changed the transmission fluid and filter around 5k miles ago and now when I rev the engine, I can hear the fluid going back and forth. My car drives and shifts fine with no issues.
I never believe in flushing just draining and feel flushing can often cause problems
You can hear your transmission fluid?
Only when the vehicle is in park and when I rev the engine. I usually let it warm it up before take off and it drives fine. I think there might be air in my fluid.
uh no. I highly doubt that's what you're hearing. The transmission fluid circuit is an open system, like crankcase oil. Not closed like coolant. That means air doesn't get trapped in it.
