Water in transmission oil. Xtrail

Hello I hope you can help me. KA is the truck, according to the mechanic, water in the transmission. A few days ago Anduve in places where there was effectively a lot of water, but it did not reach half of the tires.
The problem is K when accelerating the truck does not grab the change. I would like to know if the k tells me the mechanic, it is true, by k in another part they scanned it and according to it was the speed sensor. And it is like the mechanic is not like that and I know how to charge a good. Thanks in advance

A short response, if you have the light check on the oil nothing has to do, the box is sealed as no water comes out.

The truth is that I do not think that any of those possible problems is that the connection of the Senser Lamda (oxygen) is discovered and this when wetting I send a signal erroneous to the ECU (computer) the ideal would be to isolate the connection well and try if I do it again I hope you help you something

Look if the bombin or clutch pump is fine (it does not lose liquid)

Friends apologize is not to revat them, but they must read the questions well the Sensor Lamda has nothing to do with the speed, because their functions are different and their codes and signs do not semester or interrun, as in the case of the flow and the TPS where the ECU can confuse them, or the case of a distribution of Tienpo with an injector error code number two. Now the strange boxes are automatic and non -manuals here in Chile.
