I'm not sure if this is the correct place to ask this, but does anyone know if it is possible to easily flush the automatic transmission fluid out of a '95 Sentra with a 1.6L engine? I would like to be able to do this on my own. I was told there may be a possibility in pumping out all the transmission fluid thru the use of plastic tubing leading from the transmission to a plastic jug, but I am having trouble locating a port on the transmission through which I might do the flush. The same person who suggested this method mentioned I might look for a rubber tube that connected the transmission to the radiator, remove one end of rubber tubing and replace it with one end of plastic tubing, then turn on the engine and put the gear in neutral to start the pumping action. I've never done this before; I don't know where to begin to look for a rubber tube from the transmission to the radiator; I've searched extensively on the web for diagrams and further info, but no luck. Any help would be much appreciated.
