The transmission control module controls the transmission so it is the first place I would look before removing the transmission box.

it could be consumed by the engine and exited out the exhaust pipe.

The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
  • Check and fix any exhaust leaks
  • Check for wiring problems (shorted, frayed wires)
  • Check the frequency and amplitude of the oxygen sensor (advanced)
  • Check for a deteriorating / contaminated oxygen sensor, replace if necessary
  • Check for inlet air leaks
  • Check the MAF sensor for proper operation

Is the alternator good? If so, you are draining from somewhere else. If the amp is TOTALLY disconnected, check your starter, because an closed circuit in the starter can drain the battery really fast, and if you have had problems starting lately, that's your problem, let me know how you make out....

Try some WD -40 in the key hole. Spray a good bit in to remove any metal deposits.

With the location of the water leak and the cold air, it sounds as if the heater core is leaking or one of the heater hoses going to or from the core has a hole in it. The heater core is on the passenger side of the vehicle, inside, against the firewall. Is the carpet wet underneath on that side?

el problema de aceite mescandose con el anty congelante es por lo regular empaques de cabeza pero en algunos casos puede ser solo empaques de manifool de admission o en terminos usuales diriamos empaques de la arana asegurese que el mecanico le de un precio en caso de que solo sean los empaques de arana por logica seria mucho mas varato que los de cavezas. el caso de la cantada a que se devio le faltava agua? o estava tirando talves bueno a menos que la transmission no trabajava bien antes de la primer calentada estaria en mal estado pero si trabajo bien antes no tendra ningun problema. espero este comentario le ayude para ahorrar algo de dinero y trabajo buena suerte, informeme de lo que acontesca y grasias.
