R320 CDI 2007 OM642
Hi I just finished the Om642 oil cooler seal change, engine seems to be working good, but I get the original shutter and sluggish shifting on my transmission during lite acceleration takeoff from stop,
I went through all the transmission adaptation in DAS, but nothing seems to change
when I look in DAS under CDI4 adaptation variant coding there is one line: Series V251 Coding = New Automatic Transmission Water Sensor
I thought it should be NAG2

And in the development variant coding I get a message: one or more coding is incorrect
I Click ok and all coding is blank except in 2 places the coding is
New Automatic Transmission Water Sensor
No engine settings in the variant coding like in this video

Also I was looking at the actual torque converter values when driving, it goes from OPEN to SLIPPING and never fully lockup, little slipping during driving between 0 and 50 in DAS actual value between the engine RPM and Torque converter, is that normal, or should it fully lockup?

If anyone has any information on proper variant coding for the 2007 R-class cdi please share

No problem codes in the systems

Thanks
