I was trying to change the oil on a Chevrolet 2008 Suburban, and didn't know quite what I was doing. I used Motor Medic Motor Flush, and it said that if the car was over 75,000 since it had last been done, the oil pan should be dropped and cleaned. I'm not sure if this is actually true, since the actual oil pan looks almost impossible to remove (lots of stuff in the way). But regardless, I ended up removing the transmission fluid pan by mistake, and most of the fluid has now spilled out. Not quite all of it, though, since some actuator cable mount is holding on to one corner, and I couldn't get the pan quite all the way off. I've put the pan back up with two bolts so it isn't just hanging by that corner. Can I just bolt it all back together and add transmission fluid, or perhaps get a technician to add some after I've reassembled it? Or, have I badly messed something up by draining it like this?
Should I try to remove the last little bit of fluid? How much fluid should I put in / what is the correct level on the transmission fluid dip stick?
The vehicle is currently empty of oil with a new filter installed.
