I just bought a 2013 Mahindra 4025 4x4 and a line started leaking that comes from under the seat. The problem is that it is leaking gear oil and Mahindra says it is not supposed to be gear oil in it but the man that owned it said it was always serviced at the dealer. Now I am trying to figure out what is supposed to be in it. I really cannot get an answer. Any help would be greatly appreciated. Thanks
