    Default udt-sudt ?

    Im due for my 1st hydro service. The dealer had only udt, said udt is interchangable with sudt in the hydrostat plus tranny. Can anyone substantiate this?

    I didn't say UDT I said PUDT that stands for PREMIUM UDT,.. as far as I know UDT and SUDT are no longer available and if you are buying it its old stock,. as in discontinued. The only thing available it Premium udt,.. which is a multiviscocity to replace the aforementioned.

    Jason,

    Sorry for confusion, i was refferring the the original post UDT vs SUDT

    Although I was not awhere they renamed SUDT since i just bouth some the other week.

    There must be a lot of old stock out there so we just wanted to make it clear to the original poster the there is a difference between UDT and SUDT if thats what his store is still carrying UDT. He idid not mention PUDT.

    No harm done,.. I guess I should have clarified a little more myself.

    From my knowledge,.. they did improvements to the transmissions and hydraulics over the years,.. and to reduce cost for supplying 2 different oils,.. they incorporated both oils into one,.. Premium UDT, it is a replacement of the UDT and SUDT

    Is the PUDT priced like the old SUDT or somewhere between UDT and SUDT (i.e. are they passing on any cost savings)? Thanks.
