I have a B2410 model with 999.6 hrs on it.Changed transmission fluid to super UDT2 in march of this year with 955 hrs on it. I now am experiencing hydrostat problems.It lurches forward when going forward from stop.Also in reverse.It goes into the dealers tomorrow.I was told do not move it any more. Has anyone else had issues with the new UDT2 product?

I've used SUDT2 in my B1750 for several years now with no ill effects. The B1750 is the same generation as your B2410. Mine has about 550 hours on it.
Just a thought? Did you clean/inspect the suction strainer?

Suggest you check the damper on the hst pedal linkage to make certain both ends are still properly attached. Its purpose is to smooth out pedal movements by acting like a shock absorber.

An update on the hsd. Pressures came in spec. Changed fluid again and reverse no longer jumps. But forward does. Thinking about replacing forward relief valve. I noticed the Super UDT2 container no longer states that it is synthetic and it smells different from the product I purchased in March of this year.
The fluid was darker from when it was installed. But no metal shavings were found. Taking filters in to have dealer cut them in half. This will be done on Monday morning.
After changing fluid again that was changed 55 hr ago.I noticed differences in the smell and the color of the SUDT2 that I just purchased from the one purchased in February of 2019. The product from February had a sulfur smell to it.The new fluid did not and smelled totally different.After taking it out for a spin after following the start up procedure. All lurching going in both directions stopped occurring.I have contacted Kubota Corporate Office to ask if there was a change in formulation between the two lot numbers. I will update when and if they reply.
Reply came from Kubota. Contact Valvoline. They make the Super UDT2 for them.They would know if there was a change in formulation between the two lot numbers in question.Called Valvoline Tech Support. They said they do not make changes to product unless directed by Kubota. But they are reviewing my case and may need samples of each lot numbered product for analysis at there lab.Stay tuned. I will update when more information is given from Valvoline.
Nice job following through with the supplier.
It would really be nice if you had a sample from the original container so they could conduct chemical analysis.
Looking forward to learning the outcome.

Scotty, you have already made revelations no one else seemed to know. That the manufacturer of Kobuta's UDT2 is Valvoline. Interesting.
My dealer told me that several years ago.
I believe that Valvoline makes all of Kubota's lubricants.

your complaint is indicative of high charge pressure. Although it may be within spec, if you reduce the pressure to the lower end of the spec, it may help with your issue. Occasionally I find one that's on the low end, and increasing it a little at a time sometimes helps too. Seems like every one of them is a little different.
As others have said, thanks for the updates and info. Appreciate learning from you and your experience.

Curious as to where you got the fluid from?
Would be even better to know if someone returned the jug you bought?
Could be a simple case of some cheat filling up a Jug of SUDT2 with something like 303 which is dirt cheap, and returning it back to the store for credit.
