I accidentally put motor oil in where the transmission oil is to be placed in my BMW. I only put in about half a bottle...will my car be ok? Do I just get an oil change? Can I still drive it? What kinda of damage will this cause my car?

Well now that you have freaked out half of the auto people on here..... I hope you have not started the car or it will be too late.
Drain it, fill it up with the right stuff you should be good. The guy above who said something about draining it a couple times with the cheap stuff isn't a bad idea. Especially considering a few bottles of the cheap stuff and some of the good stuff isn't going to cost you nearly as much as the cost of a new trans.
I just hope you haven't started it already, I'm hoping since you said you only filled it up half way you haven't. Bet you'll never do it again though!

I just asked my husband who is a motor mechanic and he is horrified at what has happened. If it is an auto don't drive at all it you will wreck it, transmission oil and motor oil are not compatible. He gave a lengthy explanation but the bottom line is 'don't drive it' drain all the oil and replace with transmission oil.

You got to remember that motor oil is made to hydrosize under preasure, on the other hand transmission fluid is designed to expand so by all means your gonna need to change all of the tranny fluid and make sure you put the right kind in there. other than taking that precaution you should be fine afterwards.

I just did this as well. I only put about 3/4 cup in it before realizing I had the wrong bottle. I immediately began to siphon the fluid but who knows how much good that did. I then started the car to move it about 50 feet. So...how bad is this?

what do you mean by half a bottle?a litle bit wont hurt but if it's half a litre you should drain it through the cooler hoses not the pan,draining the pan will only get some of it out.either that or just put it in for an automatic service,the drive wont hurt it.
obviously the morons giving the thumbs down wouldn't know an automatic transmission from a steering wheel.*********.

Transmission fluid and oil are very different. Call a BMW dealer and see what he recommends. I suspect the choice will be if you drive it a few blocks to a garage or have it towed, but the transmission fluid will have to be drained and the filters replaced.
Good Luck!

worse case scenario:
say goodbye to proper tranny operations...
best case scenario:
drain all tranny fluid.. without starting the engine.. refill to proper level with recommended fluid and filter... re-flush more than once if time and patience...
Tranny might be okay!
Expect the worse! Motor oil has compounds that destroy hydraulic seals in trannys and power steering systems...
Does this help any?

Not that big a deal ,if you haven't driven it yet.Drain it after its drained pour 1qt of fresh trans fluid let drain ,replace the drain plug and top off to the correct level . Don't forget the engine has to be running when checking fluid levels.

bad , very bad . do not drive it transmission fluid is hydraulic in nature, motor oil is used to reduce friction need i say more ....drain and flush your transmission before you drive it unless you want a new one
