Choosing lever stuck in P……

Hello together, now it also caught me, the selector lever is stuck in P and cannot be solved any more. SL was towed to the friendly. The brake light switch was already excluded, so probably the hook in the selector lever module is broken (known problem ). now the friendly and I is facing a problem, we would be able to replace the hook, however to do this the module has to go out and this does not go out if the lever is on P ( middle console can not be have heard what it should work if you knock on the handle of the gear lever to unlock this. does any of you have experiences or tips? Thank you in advance Greeting Michael
