B3030 high gear

[blacklabel333]

Hey there, I have a 2006 b3030 hst and it works great in low and med gear but when you put it in high and hit the pedal it bogs down and will stall. Even if you baby it to get it moving it will lose rpm and fall on it's face. Something is wrong with the trans just not sure what. Also when its cold out she won't hardly move in any gear for about 15 min. Any ideas? We changed out the hydraulic filters and fluid and no change.

Specifically, what hydraulic fluid did you use and what filters did you use? Kubota or something else?

Second thought, are you sure you put the filters in the proper positions? I recall some reported here in the past that they got them reversed. I’m not sure what difference that made, just can’t remember.

Yes, what fluid and what filters exactly?

How does the steering react when this happens?

It's the kubota fluid and some napa gold filters I cross referenced for it. The steering gets very tight as well when cold. The filters are in the correct spots as well even went out to confirm after reading that haha.

Well there are several Kubota fluids, so that's no help.
Napa filters are not helping your case either, bad / wrong filters are known to cause issues.

My best advice is find out exactly what fluid it has in it, and get real Kubota filters, yes it makes a difference!

A HST transmission is not a place where one substitutes oils and/or filters unless one is CERTAIN that such substitutes are equivalent to the Kubota items.

If mine, I would replace the filters with Kubota filters and the oil with Kubota SUDT2.

Post back.
