I have a 2001 740i with about 90K miles that has never skipped a beat. Now, about a week ago it started to go into the trans failsafe mode and throwing a P1743 code. I have seen a number of posts about the trans failsafe and more specifically the P1743 code, but it seems that if anyone ever solved the problem they never posted what the did. Any help would be most appreciated!
The trans failsafe started about a week ago. I was refueling and when I restarted the car the failsafe warning came on and the car went into limp mode. I found the reset procedure (gas pedal to the floor) which cleared it for a couple of days. Now the failsafe is back and happens immediately after the reset, along with the CEL with the p1743 code. I tried unplugging the ABS and it does the same thing. I also checked the trans fluid and it was full. The only other thing I can think of is that the idle is rough and appears to be running rich (smell), which started around the same time as the failsafe problem. The transmission was silky smooth and never had any problems, so I don't think it is the trans. Any ideas?
