I have a 1998 740i series and I was doing some in town driving.
Suddenly the transmission seemed to jolt and then I received a
"transmission failsafe prog" message on my dash panel. I've never had
this problem before. Can some one tell me how much of a problem this
is? The owners manual says it's the "transmission control module", as
it might have a fault. Is this a costly problem? Or is it a larger
transmission problem. Appreciate any help in understanding this issue.
