Hyunday Elantra does not advance

Give help to light a car with cables, after that the car does not advance, it is slowed, it does not make changes .. Nor does it indicate anything on the board as a service light or alternator .. in advance I appreciate the help and recommendation that they can give me ..

I suppose you mean an automatic change that does nothing, it will be necessary to check from the command of it, to the pressure in the box, change the oil of the change oil ... you should give more data, to know why it stopped and as it did, if the tweezers were done well, if it starts or not, so with the data you give it is difficult to tell you (at least me). Greetings!!

It is automatic .. He turns well and everything but when I start it, he is heavy and does not make the changes .. I know that the procedure when I help I did it wrong because I did not disconnect the tweezers when they gave him to turn on the other vehicle .. after that I am so .. several have told me that it is the alternator ..

It is very possible to damage the transmission, test resetting the system, or simply at the motor

Well, I don't think the alternator has to do with change, if not, the battery is so low. In any case, you say that the changes are slow and the oil of the change and its filter may need to change, it is not that the filter is filled and does not have enough pressure so that the change works well. Greetings!!
