[Viala]

Hi

back on the forum.
I have no time to repair my transmission 4 T60 E but I don't give up the car is in the street .Battery is drained
So before doing big repairs I tried to check my old transmission in the cellar.
I have a part of tecnical book in french and I have checked the solenoids.
A and B they knock . But one named MIEV ????????? just do a bzzzzzzzzz
But what is MIEV function!!
May be MIEV a french name.
The day of the breakdown with the old transmission I had nothing on R D OD 1 2
oil was correct, it was a mystérious breakdown for me and here they don't repair they change with a new one. An idea of this kind of problem, the chain , oil, Miev

Thank you for your help
