paps03 2 #1 Posted August 21, 2015 I have a 416 hydro and I am changing the Tranny oil as well as the filter. How many quarts of oil does it hold? Share this post Link to post Share on other sites
doc724 925 #2 Posted August 21, 2015 The Eaton manual says 5 quarts, however that assumes that the pump and the lines to the lift cylinder are drained as well. The only way to get all the oil out is to crack open the lines and vent the system. I changed mine recently and chose not to do this. I just drained the transaxle and replaced the filter. It took about 3.5 quarts when I refilled it. I then started it and let it run a couple of minutes to fill the filter then checked the level with the dipstick. It needed about 2 more ounces to bring it up to the correct level. 1 Share this post Link to post Share on other sites
