Is the Daewoo Lanos transmission really unserviceable?

I drive a 1.6 Daewoo Lanos with a automatic transmission. The other when I was at my mechanic he told me that the transmission is unserviceable, and that because of this he couldn't do a transmission flush. Is this true? Do I have to wait until the transmission breaks to get service? And if it really is unserviceable how long do these transmission hold out (my car's 80,000 miles old)?|||Go to any major auto parts store and see if they have a Chilton's manual for your car. Even if you don't do your own repairs, this can help you understand what's being done with/to your car. An automatic has a pan underneath that can be taken off to drain the old oil and replace the filter, so look underneath to see if yours has one. If so, find a new mechanic. I can't imagine anyone making any transmission that can't be serviced, not with cars commonly being used to 200,000 miles now.|||Not sure on the logistics, but it uses a GM transmission, the same one found in the Sunfire and probably the Cavalier. If you take a look at how to service those trans, with which there should be plenty of information and documentation, you should be able to get a better idea.|||just about any transmission is serviceable. take to a quick lube to see if they can do. Most will disconnect the transmission lines that go to the radiator and use a machine to flush and replace the fluid. Maybe your mechanic does not have this machine?|||you sure you were at a mechanic? that guy moust of been smoking crack.
