2004 745Li Transmission Failsafe
Hello everyone. I'll start off by saying thanks in advance to anyone who can shed some light on my issues. I've found this forum to be a great source of information when it comes to these beautiful cars.
My car is a 2004 745Li with a transmission issue. I've had it for about a year now and it's always shifted a little rough. Worse when cold. When driving down the highway and in 6th gear it will randomly slip out of gear and rev up about 1000-1500 rpms for about 2 seconds and go back into gear. On occasion it will be bad enough to bring up transmission Failsafe on the dash and then it won't even go into 6th gear. Lately when starting the car, I'll put it in gear and it will automatically say transmission Failsafe and refuses to go into drive or reverse. Please help. Awhile back I had changed the integrated supply module in hopes that it was part of the issue, but no luck there.
