Ok I have 1990 Rx7 turbo and today I decided to check the tray oil level. So I jacked up the car and unscrewed the check plug (not the fill plug. there is 4 plugs on the turbo trany two drain one check and one fill up. The fill up is the highest one) and oil just purred out of it. So I assume that prev owner of the car (I bought the car 3 mo ago) instead of filling the car to the level of the check plug filled it to the level of the fill plug which is like 50% more oil then needed. Would this damage seals on trany or damage anything else?

The reason I’m asking is the reason I checked the level of oil in trany, and the reason is that if I drive the car for more then 10 min when I stop and get out of the car I smell burned oil and if I will abuse the car ( like going 140 mph on freeway) it will start smoking really bad from underneath of the car ( not the engine bay just some smoke coming form there) . Anyway so I looked under the car and I could see some oil on catalytic converter (the main/big one not the one coming right after the turbo), and is smoking. While I had the car on the jack I tried to find something with would show that it is liking from the trany but there was nothing definite except overfilled oil(another word I could not find the place it would leak out of the trany and then drip on to the converter).

 

Oil will leak out of the tranny until the tranny is at a good level. It is probably leaking out on to the cat and is burning.

No, i dont see why it would harm the tranny!
Hope this helps.

Too much oil could cause foaming. that would be bad.

 

So far nothing bad. Thanks guys. I don't think I have foaming because when I drained the oil id did not see anything strange about gear oil it was the color it should be and it did not have bubbles in it (I assume that would be foaming -- bubbles or it would have some white color in it. Right? )

 

I did it like 5 min after the car was shut off

 

be safe and change it out

 

I was plning to do it anyway just never got around to it. thx
