Dipstick bubbles?

[bambam78]

Hey guys, Just had a quick question to shoot out, my 4l60E leaks tranny fluid constantly, from pan, and the front seal, so i'm constantly checking it and topping it off, it's not a fast leak, just a few drops here and there, transmission shifts good, a little hesitant when you first put it into reverse though which i assume is normal with these trucks?

Well recently on my dipstick i've noticed a lot of bubbles, almost like a froth, just wondering if it was anything to be worried about, and if i should swap my fluid?

thanks

That is a bad sign. When the transmission is overfilled it can whip the fluid up into a froth which thins it out and weakens the fluid's ability to perform its functions.
