I have a 2015 cruze LTZ R/S. It has 45,000 miles so i did a transmission fluid change. I used a set of ramps to drive on to perform the fluid change. I added 4 quarts of fluid drove it down the ramps and took out the seep hole screw. about 2 quarts of fluid poured out. Does anyone know why this would happen? I am thinking since it was on ramps when i changed the fluid that maybe all the fluid did not drain. my manual says about 4.2 quarts will drain. any help or insight would be helpful. Thanks in advance. Lee
