Needing parts l3830

[Hemphill1992]

Hello first time posting. We have a l3830 that we had to repo from a guy and we think he used the wrong oil in the Hst and now it will not move. Took it in and apparently there is no psi being made in the pump and a lot of brass in the hydro fluid. So we are trying to find a parts tractor that we could swap the whole transmission into ours. Thanks in advance for the info. This our first Kubota and we don’t know much yet about them. Thanks
