7G-tronic gearbox don't lock-up when downshifting

My car is '06, e320 cdi (om642, 722.9 / 7speed gearbox).

Here is the situation.
When driving 50/60km/h and have to slow down, and down shift from higher gear to second or third gear, after that gearbox not lock-up, so when i push the gas, RPMs go high - 2500/3500 rpm, but no torque, it's very slow accelleration, no lock-up. It's feels like the gearbox is slipping. I have to drive for a while(100,200metres), until lock-up start locking again.
I know that lock-up is not fully locked-up, but in the situation, it's abs. unlocked.

In other situation, when accelerating from 0km/h it's ok, no such problem of slipping.

Any advice, where could be issue?

The(your) problem with 7G shifting issues is that all everyone can do is speculate/guess or provide HS replies without the correct diagnostics----My HS response is that you have a couple of bad shift solenoids located on the conductor plate---now how to convert the HS into fact----find someone with DAS Xentry and knows how to use the system---The other issue with so called indies is that MB classifies the conductor plate a TRP(theft relevant part) means no ticky no shirty!!
