Sou, hello guys, story time MB C class s204
gearbox 7G TRONIC

i bought car with the problem, dpf is already deleted, car transmission was changing gears to soon and feel like little bit slipping, it was 100% noticeable that something is wrong after some time gearbox ecu died and engine was not showing gear numbers also car was not enable to start!

okey

I replaced whole gearbox with 100% working one, dialer programed it to at least start the car!

BUT

Now with new gearbox i has same problem changing gears to soon and feels like little bit slipping.

....

Do you mean replaced the whole gearbox with TCU ?
Actually if those gears are not damaged no need to replace gearbox.

What fault codes you have found ? 
This is important to read fault codes, not just read TCU, need to read the whole car,
blind replace parts won't solve problems.
Have you do proper coding to TCU ?
After coding, have you do up shift down shift adaptation ?

If ECU problem also will cause some running problems...
But hard to tell.

Feel like shift quality is not good.
that will not get any fault codes.
Try do shift adaptation in Xentry, but need on Dyno,
On road is very difficult.
Normal drive can also do that but need to drive around 100km and prevent press hard on accelerate paddle.

also try pull the adaptation data see if anything out of range.
