How and when do you change transmission oil on a Daewoo Lanos 16 L?

Answer 1

Most of these Daewoos out on the market today do not come with owner's manuals any more, or spare tires, or radio reset codes, or jackstands for that matter. Mine didn't. The general public (including GM) has scrapped Daewoo, that's why they're so cheap. I also need to know how to check the fluid. Most cars with an A/T require the transmission to be hot, engine idling in park, to check the fluid level, but not all. On some you check it cold engine off. The problem with not knowing for sure is that overfilling the transmission can damage it. For that reason I suggest you get that owner's manual you are missing. Sources are dealer, salvage yard, e-bay, and many on-line sites. Search with the term, "Automobile Owner's Manual". Draining and changing the fluid can either be accomplished by removing the drain plug if it has one or by removing the return line from the radiator and with a helper starting the engine and allowing the trans pump to pump the fluid out one quart at a time. Pump out one quart in a clear container and then stop the engine and add a quart of fresh fluid. Keep doing this until you see clear clean fluid. This will actually remove all the fluid and is better than just draining the transmission pan, which only removes some of the fluid. You will also need to know the exact type fluid to add. A call to the dealer can get you this info.
