Trans failsafe program, how to reset it? - 1997 BMW 7 Series

First check transmission dip stick for correct fluid level. Next schedule a transmission filter change. This should have been done at 60,000miles

Depends why the Failsafe was triggered. Read the codes would be a good way to start. Anyway, since the car wont start, it may be the crankshaft position sensor, which will cause a trans failsafe and prevent the car from starting.

The 'Trans. Failsafe Prog' display indicates a general fault within the trans and this should leave a fault code which can be read off to pinpoint the exact transmission problem. Without this code it will be difficult to correctly identify the source of your problem.

Drop the trans pan and check for debris -- if you have metal in there, then you're going to need a rebuild.

Keep driving it, you will have a $5,000 repair bill

Stop using it & hope you can save the trans with the
proper diagnosis, to find the reason it went into failsafe

The transmission has gone into limp mode. My Boomer done the same thing' if it wont reset itself i think the only option is a BMW dealer to faultfind. Very complicated computor controlled transmission beyond any novice im afraid.

Your transmission is going into limp mode because of a fault. Get the tranny diagnosed.

I would not be surprised if your module or parts you replaced needs to be programmed or put in sync with the transmission computer or engine computer. Check with the dealer. Sometimes they have some silly or eccentric methods to get everything working together again. Cars are not very owner friendly anymore...

Simply put this car i have no idea what version software is in it, or if it has been serviced regularly so. The best thing to do is take it to BMW there were many recalls on this subject trans program light this may be something which will be fixed at very minimal cost or even free.

have you transferbox Shift motor and your problem is solved

im sorry to say but it is kinda common for the trans to go out and need replaced on the e-39, you would first want to have it scanned and see if there is anything the dealership or an approved independant shop can do for you based on the codes, good luck
