my never ending Trans Failsafe Prog saga, come on.....
it was raining for the past week and i don't understand why is it always during rainy days that i experience this Trans Failsafe thing. 2 days ago i've sent the X5 to a BMW Service Center (not the dealer) to replace speed sensor turbine in the trans. found out that the sensor itself is loose and they have tighten up the connector, the X runs fine for the rest of the day. following morning trans failsafe again, once restarted never came back, why it's only in the morning? (i'm always getting this every morning atleast once before). today same issue but this time my alternator died. replaced it with the new one (Bosch) but i'd thought would solve the issue as i've read some post that it could be an alternator. scanned it with the GT1, now the DSC module seems to have an issue but why it's not showing prior to this? did a quick delete and did not appear again. now i'm getting an intermittent trans failsafe. any suggestions? is this a sign of serious problem with the tranny?

thanks.
