How to check auto trans fluid level?
Sorry this is a simple question. I am getting some tranny fluid on my garage floor, and have an appt in a couple of weeks to get it looked at. In the meantime I want to check to make sure I haven't lost too much fluid and whether I need to top off. There isn't much on my garage floor, but the car is also parked at work every day, so I don't know how much I've lost.
Tried a search and came up with too many hits to wade through. Thanks in advance for the help.

You'll need to drive around to heat the transmission up, put the car on a lift or jack stands (level), and open the fill plug on the transmission. Fluid should be weeping out if it's full. Otherwise you'll need to add fluid until it starts to come back out the hole. Unfortunately there's not a dipstick or an easy way to check.

If you open that fill hole a lot of fluid is going to come out. Yes, out of the fill hole. I'd leave it be for now personally.
Fluid leak is probably coming from the tranny pan gasket or mechatronics sleeve. |

I was pretty alarmed the first time I did a fluid change because so much came out of the fill hole. I actually thought I had removed the drain plug by mistake at first. |

I just did my tranny drain / fill last week - keep the engine running, then open the fill hole, if its low on oil it wont drip out, slight drip out means you're fine - with out engine running you'll drip 1.25 Qrts, thats the silver bullet in tranny DIYs

+1 on this! Engine must be running to check transmission fluid level.

This time of year, operating temp should arrive pretty quickly.
According to Bentley service manual, 86 degrees is ideal, and an accurate reading is not possible above 122. |
