Is there a transmission software update for a 2008 c300
Hello all. Please I have a 2008 C300 4matic sport. I would like to know if there is any transmission software update for it? There is a lag when there is a shift from P to D. The car drives smoothly and changes gear smoothly. Just the little lag when put from P to D. Any one experienced such?
Also It happens when it is put to R, there is this 1 second lag before it moves. I saw through a glass reflection of the side that when I put on R, the 1 second lag happens and then it is when the reverse light comes on that it engages.
Are these normal?

Dealerships in USA refuse to update anything software wise which is just them covering their behind in case they mess up.

That's very strange. When i got my 2008 and went to get recalls done, they told me there was a TCU update available and the transmission definitely felt a little smoother after that. That was a long time ago but I don't see why they would refuse. I tell anyone that gets a used car to call their dealership and see if there's any recalls or software updates available for their car and 9/10 there's always something.

But the reset made my driving feel like as if it’s a new car I am driving. Thanks for this.
Heard it’s good to do a transmission reset every month.

Ok. Did the transmission reset and wow the gear shifts smoothly like new. But still has that 1 sec lag when put from P to D or R. I think that’s how it was designed for.

No it's not normal, but to diagnose this, you're going to need the Mercedes Benz diagnostic tool to see if there are any transmission control unit fault codes and if not, to read actual values related to the operation of the transmission to try and diagnose what is happening.
First of all, how many km/miles on the car and when was the last time the transmission fluid and filter were changed? The change interval for this car is every 40k miles/60k km or 5 years; whichever comes first.

In this case, you'd have to take the car to an independent shop that has the MB diagnostic tool. He will then connect it to the car and read live values as you shift. He should be able to see what is causing the delay. It could be that the solenoids in the conductor plate need to be replaced or a sensor or some other part delaying the shift.
