Re: automatic transmission fluid drain?
look in the field service manual, its under the "maintenance" section. There are 2 ways to do it.
1. Drain it from the drain bolt located on the bottom of the CVT transmission oil pan. Refill from the top in the charging pipe. Holds 7 1/4 quarts. Drive car for 10 min, check fluid level. Refill as needed
2. Drive car for 10 min, leave car running in park. Uplug return hose on left lower side of radiator that goes to the CVT, unplug from the CVT itself. Lay this hose in a drain pan, preferably a large one, your going to be pumping out about 10 quarts. Note, hose running to lower right side of radiator is the sending line to radiator, do not remove this line. Add fluid to the CVT charging pipe as the car is running and pumping fluid into your drain pan. When you see the old dark fluid start turning to green new fluid. Turn the car off. Re hook up drain line to CVT. VERY IMPORTANT THAT YOU HOOK THIS LINE UP WELL, BECAUSE IF IT COMES OFF, YOU WILL LOSE ALL YOUR FLUID AND THROW YOUR transmission INTO DEFENSE MODE. IT WILL LEAVE YOU ON THE SIDE OF THE ROAD! Drive the car for a few min. Check level, add fluid as needed.
Positives and negatives to both.
First one, quick and efficient. Less time consuming and uses less fluid. However, leaves old fluid in cooling system of transmission. Takes 8 3/4 quarts.
Second one, most clean way. Replaces all the old fluid. However, it takes 30-50% more fluid to do it this way. 10 3/4 quarts or more, depending on how quickly you catch the new fluid coming out of the return hose.
I recommend doing it the first way, leaving the small amount of old fluid in the radiator will easily be diluted by the new fluid.
