As long as you have no visible leaks and the level is correct when the transmission is warm (that is also a variable here!), you are fine. It could have been slightly underfilled at the last service.

i checked again the transmission fluid and its over the maximum level
Depends on the amount. As long as you aren't getting any shifting issues, it will (probably) be ok.

Also, the trans dipstick isn't the easiest to read. I have found that you can read the level more easily if you use a paper towel to help discern the level, like this:

That was with a fairly cool transmission, shows the level right above the min mark. the two marks to the right are cleaning wipes before inserting to read the level.

Without that trick, the wispy marks above the full level can fool you into thinking the trans is overfilled. Works on the engine dipstick too...

Here is the reading ahen engine is cold, and i did the engine off then measure it gave me a little more or above the max level
Based on what I'm seeing there - You might just want to do another drain and fill. The trans fluid still looks a bit brown, which hints at a need for new fluid in there anyway. But your trans isn't going to blow up if you drive it some more with those levels.

i actually changed and replaced the transmission fluid a few days ago
You did about 1/3 of the fluid a few days ago. If it isn't red, it is likely worn enough to warrant another drain and fill. The factory 30k drain and fill interval is often inadequate.

if they roccomend changing the tran fluid 3x could you give me a strp by step on how to fill, drain then drive again and repeat the process
You just did it there yourself. The transmission holds about 3x the fluid that comes out when you drain the transmission from the drain plug. The rest is located in the torque converter and other fluid passages in the transmission. Since Honda specifically recommends against any "power flush" technique on their transmissions that could truly change all of the fluid in the transmission, they recommend draining and filling 3x with some driving in between each drain and fill. That gets the majority of the old fluid out without risking any damage to the transmission.

If you are going to DIY such a procedure, the easiest way is simply drain and fill on 3 consecutive weekends.

Since the fluid looks a bit old in your transmission and you are going to mess with the level anyway, now seems like a good time to do a little bit of 'catch-up' maintenance with another drain and fill... If you aren't noticing any poor shifting, etc. you won't need to do any more than that.

In the future, if you blot the dipstick with the towel you will be able to see where the fluid film ends.
I took a picture to explain this...

That pic shows the level just between the high and low levels (trans fluid wasn't hot, just a bit warm).

I bet it was filled to the 'full' line when cold... That plus draining at an angle (which is fine/good) accounts for the large drain amount.
