Getrag G360 seal kit?
 

Is there a kit that just has seals in it? Mine trans is leaking like a sive and figure Id just reseal the whole thing.

You can probably buy just the seals from somebody like Z-Bag or Standard Transmission.... There is only 2 of them on a D-250, one in the front and one in the rear... I think the W350 has three.... an extra going to the transfer case.
