Reverse lights on while shifter is in Park on a 1993 BMW 525i.

SOURCE: Car not shifting into second gear

If the car is grinding when going into reverse, you need to have the clutch bled or repaired.

If it goes into reverse with out grinding, I am sorry to tell you your problem is internal to the gearbox. Bad or damaged Syncro

Good luck

you need to have the shifting cable lubricated or replaced.

SOURCE: where is the transmission dip stick located for the 2002 525i bmw

it is a sealed trans. you will have to bring it to BMW to have them take a look.... they dont put a dip stick on that car and many other's so you can't do anything except bring it to them to have it worked on... sorry for the bad news.... hope this helps you

The problem that I could see is the transmission/shift solenoid. The solenoid thing is located inside the transmission. The repair should run $200-$250 or there abouts. If you don't fix it quickly though, you will wreck the transmission and you don't want to know how much that costs!

You may also contact the manufacturer for second opinion.

Hope this helps and have a great evening!
