Trans Fail Safe Prog
 

Hello guys,
I drive an X5 3.0i, I took it to the workshop for servicing, the nozzles were removed and serviced then replaced, after replacement the error Trans Fail Safe Prog was displayed on the dashboard. I ran a diagnosis with the diag equipment, the diag error is 146: CAN Torque Interface.
Please is there anybody that know the meaning of this? how can i go about it please? i have remove the battery terminals for 15 or 20 minutes before now.
I will appreciate a quick response
Thanks guys
