95 bmw 525i.... transmission issues and more

First thing to check is the voltage at the gearbox ECU - if this is low for any reason, poor connections, alternator or battery fault etc, one of the first symptoms of this is the gearbox going into limp home mode.

Where is the ECU located. I have been having problem with the electrical charging system. When I remove the lead from the battery while the car is running it shuts off immediately. I had the alternater checked by autozone and its fine. THANK YOU FOR YOUR ADVICE AND QUICK RESPONSE.

You should *never* remove a battery connection with the engine running. The volts can go sky high and fry things. Start the car, and check the battery voltage after about 15 minutes running and report what it is.

I checked the voltage and it read 15.26v . like i said the car is not in my town so it takes a while to get to it. let me know what I can try next.

What he meant was start the car run it for 15 minutes, **stop the engine** and report what the voltage is.

BTW taking the battery lead off while the engine was running has probably done for a lot of the electronics :-(((

I'd suggest seeing a professional. It really sounds as if you're out of your depth here - and you're causing more damage trying to fix it than there was to start with. 15.26V is WAY too high - with engine running or not. You may have an alternator problem rather than a transmission problem, but asking for help via the net is asking for guesses by people who aren't near your car.

See a dealer. That's what I'd suggest you try next.

Assuming you have an accurate voltmeter that's way out of tolerance. Hopefully when that's rectified by a new regulator the transmission fault will go too. The voltage should stabilise at 13.8v after a few minutes running assuming a decent battery in a good state of charge.
