Hello evryone I am new to this forum. I have a 2006 m5 85k miles smg. Ever since I bought it it has been having smg issues. 2nd gear is the issue for me because it throws a red cog if I wot going into 2nd or downshifting from 3rd to 2nd. My Indy is telling me to replace whole transmission with a used one. My fault codes are 4f40 and 4f85. I know 4f40 means smg pump undershooting but I don't think my smg pump is bad bc I can hear it prime when I open door. I've had the car for 2 months and all I've been getting are headaches. I talked to Troy and was going to go to his shop but have done so yet. Any help would be appreciated.
