foamy gear oil

[califkid_66]

i usually check everything before going for a ride today im leaving it in the garage but didn’t use it for a week so i just started the engine let it run like five minutes all seemed ok so i decided to top the liquids
all was good until i opened the transmission plug  usually i check with cold engine but this time i didn’t and when i removed the transmission plug it was foamy and started leaking on the ground usually i put in about 100 to 200 ml cause it leaks a bit and when it’s full the overflowing oil is nice never seen the plug or in the transmission a different texture
i don’t think this is normal i used the same oil
it looks contaminated but how ?
thanks

I would check to see if the transaxle’s breather is clear.  Condensation will build up if it is not.  Clear the breather, change the oil and keep an eye on it.

dumped the oil today was not as bad as i thought
was thinking it was all foamy but it was just a little floating on top
