Sounds like you maybe having a sensor failure (engine). A computer diagnostic can be performed at the vehicle dealership to determine what caused the fail safe mode to activate.

Before you make any other moves, I would try having the transmission flushed and refilled and filters changed and if that doesn't work, you may have burned out the modulator so you may have to shop around for another transmission or have that one rebuilt, whichever would be feasibly financial for you.

SOURCE: BMW X5 Trans Fail Safe Program,

sometimes it will clear if you turn the X5 off and restart it. however, it could be an early indication that the tranny is about to expire. i have had it happen and it cleared with a power cycle, but also had friends where it cleared for a few weeks/months and returned. this time it was really the transmission that went bad. if you can't get it to clear, then i'd suggest taking it to the dealer and have them plug into it to have a better look.

SOURCE: BMW X5 Trans Fail Safe Program,

IT'S VERY EASY TO RESET THE TRANSMISION'S COMPUTER. HOLD GAS PEDAL DOWN. TURN THE KEY TO THE NUMBER TWO. CONTINUE TO HOLD THE GAS PEDAL DOWN FOR THIRTY SECONDS.RELEASE THE GAS PEDAL AND PRESS THE BRAKE PEDAL FOR TEN SECONDS. NOW YOU CAN TURN THE VEHICLE ON. THAT SHOULD TAKE IT OUT OF SAFE MODE

That is a pretty robust transmission but its computer is very sensitive the quality of the electrical supply. If you take it to a shop, they will probably put a known good battery in the car and check and clean the electrical grounds before they even look at the transmission. If this is your original battery, you will probably save yourself some money (and perhaps a trip to the transmission shop) if you replace the battery yourself and clean any ground connections you can find. Sorry, but other than the one near the battery, I am not familiar with the ground locations on this model, though there should be a ground strap around one of the engine mounts that should be inspected/cleaned.

My BMW 2002 starts out good in morning but when it gets warm or hot my transmission failsafe light comes on what can I do


BMW has been using electronically controlled automatic transmissions in most models since the late '80s. These transmission systems employ a transmission control unit which controls electrical solenoids to manipulate the various control and shift valves and functions in the transmission valve-body. When the transmission control unit detects a problem that it "thinks" could be damaging to the transmission or engine, it goes into a fail-safe or "limp" mode. In this mode, the transmission will function in reverse normally, but in forward it will operate in only one gear (whether you have the shifter in D, or any of the lower gears). This will typically be 3rd or 4th gear, depending on the model. It will start in this gear and stay in this gear with no shifting. You would experience this as sluggish acceleration and higher than normal engine speed at about 40-mph and above.
If you must drive the vehicle when the transmission is in the fail-safe mode, accelerate gently and keep the road speed lower than full highway speed.
Earlier models do not employ fault codes and must be diagnosed manually. Late models do employ fault codes and a diagnostic/scan machine can be used to check and read the faults to assist in diagnostics. Note that this is not your common OBD-II engine management fault code tool. This is what A BMW dealer or a properly equipped independent shop would have for full vehicle system diagnostics and coding operations.

I have a 2014 Nissan Altima that won't go or reverse could that be the transmission module???


car is only two year old

wont select reverse of revs out in reverse?

module says std automatic and not a CVT transmission
when a module goes into fail safe you always have reverse and third

check oil level first
wont select
check shift cables or linkages adjustment shift stick alignment

revs out
more likely a solenoid or mechanical failure
if there is a bang as you shift into reverse its the oil pump

if none of the above are the cause
could be the module ......not sure on that
