Should I change my transmission oil?

[NewClimber]

While during my routine weekly checks on a B7100 Kubota I have, I noticed that my transmission oil is "foamy" for a lack of a better discription. It is full on the dip stick but is has much foam inside the fill hole.

Is this normal?? I bought the tractor from a dealer last year (about 40hrs ago) and they told me they did a complete maintenace, lube, oil change, transmission change, etc. before they deliveried it. I do have a small leak in my transmission so I added some at the beginning of the spring.

So, my questions are, I added kubota UTD hydrolic oil to the transmission (dealer told me this was what I needed). The manually and stickers on the side of the tractor say SAE80. Did I put the wrong oil in????

And What is your opinion on wheather I should change this now??

Thx for the help.

Where there are air bubbles present there is no lubrication getting to the parts, depending on of course how bad the foaming is. Are there any additives in the tranny? not sure what else would cause the foaming. Perhaps SimS can shed some Pessimism, I mean opptimisim on the situation

No additives that I know of....I was thinking on adding more oil but I didn't know how bad it was if I were to over fill the case.

The only other thing was maybe the place I purchased the tractor from last year didn't use the UTD, and then I went in behind and added this...now I have 2 different oils in the same transmission

This may not be the best advice but I'm real **** over my tractors, I personally get sweaty palmed and freaked out if I think somethings wrong that I dont have a difinitive answer for. personally, I would of already freaked out and changed the fluid and filter, but thats just me. That way I know whats in there and I can rest at ease. The fluid is alot cheaper than a new tranny. I run amsoil in all my stuff.

You may have water in your oil. Yes change it.

Thanks for all the replys...I think I will take you advice and change it...

Just so I am not getting bad advice from my dealer...I should be using the standard UTD here correct??? It is a manually tranny...

Foamy oil don't lube well.

May cause cavitation in pumps.. which destroys them... Could be from water or air entrainment.. or use of a incorrect oil that doesn't have anti-foaming qualities...

I'd change oil and filter and re-check
