I have a 2015 civic with CVT. I drained the transmission and removed the overflow/level plug. I then added new fluid until it started to dribble out of the overflow. I replaced the overflow plug, started and shifted into all gears for a few seconds. Just to make shure, I shifted through the gears a second time. I then removed the overflow plug and added the rest of the 4th quart of fluid. I expected to see fluid dribbling from the overflow, but that did not happen even before the 4th quart was empty. The dealer sold me 4 quarts and it looks like the capacity is 3.6 quarts.
What went wrong? How do I know if it is over filled? Should I drive it a few miles and then raise the car again and check the overflow?
I had the same problem last week when changing the transmission fluid out of a 2014 CVT civic. I followed the instructions in the description of this videoI did have the car level with jack stands, so that was not the problem. I am thinking it might be because is was not at operating temperature. I drove the car a few miles and will now check the overflow at operating temp. I expect to get fluid from the overflow.
