at my wits end
I have a x5 3.0 06, my check engine light came sand I ran the codes and was a air flow issue. Now the trans failure Prog is coming on. When I drive, I can feel a hard shift between gears and when I slow down to stop, there is a jerk like the truck is skipping gears to get back to first gear
Anyone knows if the two issues are connected

Trans failsafe prog error is to do with the gearbox not air flow problems. I only had this error once and too the truck to an Indy. He told me that it was due to a speed differential picked up by the sensors in the gear box. He flushed and changed the oil in the transmission and replaced the filter - problem sorted.

@white lancer
It was the air flow problem that was causing the trans failure program to kick in. I took it to my mechanic and he found a hole in air filter hose. As soon as he repaired that, the codes reset themselves. But thanks for the advice anyway.
