Dear All, my E63 run for 103500+ km and changed the transmission fluid for 5 liters (cleaned pan and relaced new filter) 4 weeks ago. And the car running smoothly. However, starting from this two weeks, especially when running the car in S mode (C and S+ mode also have the problem but not that much frequently) and the car stopped in traffic light, car park gateway.....etc, stepping the accelerator to start, the car slipping (rpm to 2000, then suddenly drop down quickly and go up and drop down, then gradually become normal to accelerate), especially when starting from a slope road.

So, I am thinking if the transmission fluid 5 liters enough for the car? How much actually needed when change the fluid? Any idea on the slipping issue?

Thank you very much

 

Oh my gosh! Did you not change the fluid according to everything you can find on YouTube and this forum? I wonder if you used the right fluid. 5 liters is hardly enough if at all when doing a drain and fill with a new filter.

 

What JR said…also, in case not obvious already, do NOT keep driving it in current condition. Even slightly under filled transmission fluid can lead to issues…ask how I know.

 

Hope your tranny isn’t toast based off your lack of research lol.

 

+1:

 

I'm curious what color transmission fluid you used. Red or blue?

 

5 liters? Way low. The correct procedure is pumping fluid in from the special drain tube after reaching a specified trans temp. When the fluid drains back out WITH THE CAR RUNNING. You are at the correct level. Think more like 7 liters. I don't even know how much went in because I waited for it to start draining back out.

 

... latest is purple

 

Is that red and blue mixed together? JK. 😉

I hope OP's car is fine. I thought Albert would be smarter.

 

yes, exactly half 'n half

You got to hand it to whomever decided dipstick service was too easy.

Refilling through the drain-plug with engine running... so much better

 

Bringing up color is hateful.....

 

I can only guess it was Blue. Red is much smarter.
