Hello, I thought I had the right part number when I ordered an ATF dip stick, but the one I got is too long by about 12 inches or so.

This makes it impossible to get an accurate ATF measurement.

Can someone tell me what is the right part number or just as good the length of the dip stick from the end to the cap portion that sits on the top of the ATF tube when you take a measurement.

Thanks for any help.

What year is your C280? If it's a V6, then it must be a '98-2000. If so, then the transmission should have a sealed dipstick port, only accessible by the dealer, unless you removed the sealed tab. If so, then you have a shop dipstick, which is longer than the dipstick tube anyways. To measure with the shop dipstick, push the dipstick in until it bottoms out in the oil pan, and read the measurement.

That means I just bottom the dip stick on the ATF pan and take the reading at 80 degrees C.

When I do this now the reading is over the top of the full mark with the motor at 25 degrees C where the marks on the dip stick are near the bottom. So I must have too much fluid in the AT Tranny, correct.

And the hot reading is done when the car is on and in Park?

Please let me know if the above is correct.

Thanks,

Don't worry too much about the fluid level at 25 degrees. Drive the car to get it nice and hot, then check the level, car running and in park. The fluid should be in the 80 degree range.

Thanks for the advise. I will try that on Friday and see what I get for a level.

I see you live in Calif. What area?
