after driving the car for a while there is a an fail safe transmission alert that comes up on the dash and the trasmission goes into slump whi1e im driving it
there is a fail safety transmission alert that comes up on the dash on 1998 BMW 740iL
I have found that the transmission is sealed for life and supposed to not need attention. The truth of the matter is if you service the transmission once a year the fail safe light will not come on you probably need transmission fluid have it serviced or service it yourself I even had my seals done last year and it runs better now.
thank you for that input, i found out my battery was dying and i replaced the battery the transmission fail safe alert went away and now the car is running good,got this information off of beemerfeast .com for bmw all makes and models found it to be informative,,
