just been out for a spin in the 6, and noticed that the J type overdrive seemed to be engaging randomly in 2nd,3rd & 4th gear with the switch on the steering column in the off position. Once home I tried overdrive with ignition on and could hear solenoid switching in 3rd/4th gear, I am concerned that it might engage if I reverse into garage. Has anyone had experience of this problem and if so could you please point me in the right direction.

Regards
