I have a 2002 Mercury Mountaineer, same as the explorer. My od light started flashing and I had Ford service center run the code, code 755 solenoid b, I had the Ford service center replace it to the tune of $698 on March 5. I got the truck back March 5, 2009 at 12pm. March 6, 2009 8 am, same issue. I took it back to the service center and I'm told I need a new transmission. March 9, 2009 I took the truck to 2 separate shops, one of them being a veteran transmission repair shop. Same solenoid code 755 solenoid b. I took it back to the service center and am told that they will replace and I still need a new transmission. The transmission repair shop told me that Ford knows of the problem and it is not the transmission, the wiring harness is bad which causes the solenoid to show as bad and show the code. She said she has had dealings with the same service center and everytime they tell customers they need a new transmission. There are thousands of complaints online for the same exact issue.
