covers all ways to do it right and wrong.

Just standard ATF, Not type F. Actually I have heard you can use any Tranny fluid in Non Ford models but can only use Type F fluid in Ford model vehicles. I used to use type F in my MOPAR with Performance engine and Tranny with no problems. But if you are worried then use ATF or ATF+4 fluid and you should be fine.

read the operators guide yet?
sure lost.
the dip stick , note the large dip tube, that also serves as filler pipe.
do not fill it like the engine, or you will cause the ATF to foam up
and wreck the tranny.

many cars use this method, be sure to get your book and your method.

I know from experience that you should only use manufacturer recommended fluids in your transmission, Especially toyota, they are very peculiar about the fluids you use in them. Although the fluid you put in it may not cause any harm, it is always best to use the fluids recommended.

OK. First, find your reciept and find out what type of fluid was used and how many quarts. Next find out what type of fluid you should use (because the wrong ATF or wrong amount can cause your symptoms). The fluid can vary from transmission to transmission even though you have the same year car model. There are at least 3 transmissions for VWs for the same year (turbo, 2WD, AWD)

To make sure you know what fluid goes with YOUR transmission, you need to know the transmission number. Next, look up on ALLDATA (or ask the dealer to print this for you) the tech sheet on what fluid goes to what transmission.

Also, ALLDATA will have a page detailing the correct amount of fluid to be used. For example, a complete tranny rebuild may take up to 11 quarts, but a tranny service may only take 5 quarts.

To fill VWs with ATF (tranny fluid), you usually have to pump it in with the engine off from the bottom of the car. This means you have a hand pump that sucks the (correct) ATF and then pumps it upwards into the pan thru the drain plug. Once, you put in at least 3-4 quarts, you lower the car and turn it on and re-raise it.

While the car is on, the ATf you just pumped into it gets sucked upwards inside the tranny.
Now you start pumping more ATF upward until it starts to puor out at a steady, but solid stream. Then you quickly close the drain/fill plug and you're done. It is really easy to not put enough ATF into the system since some techs and mechs only add to the car when off, not off then on.

Also, if you have the wrong ATF in you car, you can sue the dealer for putting in the wrong ATF, thus causing damage to your tranny. This holds up in court and you get a new tranny free of charge.

Please remember that the WRONG ATF is very, very easy to use. And the wrong amount is very very easy to achieve. These (2) points are your starting points. Good luck.
