Hello guys my name is jose and this is my bmw story:
last year I bought a 2005 525i from a cousin, long story short.
I was driving my car in a highway in Texas and suddenly a red screen apper in the I drive saying transmission fault acceleration reduced. I parked the car in a gas station turned off and then turn it on and everything was cleard and no keep driving. When I reach my destination park my car and latter the day I discover my reverse wont work and I can barely accelerate and the same red screen, parked the car for a month. I got dired and I have to drive the car back to my hometown which is 150 miles and drove the car with the red screen, I was able to get home so park the car again. Next day turn it on to try to see what is going on plug the scanner in the car and get this codes
p0700, p17f1 and p17f6 the car have 150000 miles and I think never got new transmission fluid.
start the car and sometimes works good and some other wont engage reverse and reduced acceleration, I need some help guys

My transmission pan started leaking at 120k , got the transmission safe mode message ( I was low on transmission fluid so I ended up getting the pan/filter/valve sleeve including solenoids replaced. No problems. Fast forward to 250k, transmission started acting up on the highway going up hills and slipping from 1st to second. If the car was on a slope, I couldn't get into reverse without the transmission fail safe mode idrive message popping up All the BMW shops kept telling me to get a new transmission or a new car.I decided to check to see if the atf was low and ended up buying a gallon of fluid and found out it was 5 liters low. It runs perfect now. (For now) have a shop or DIY, have them check for leaks and open the fill valve .if it's full, a little should drizzle out. If not it's low. Pump a little fluid in, start the car and keep pumping more atf till it starts leaking out the drain. This is the first thing you should check before going on to step 2. This should only be a temporary solution and you should eventually get the transmission pan and atf replaced.
