if you are referring to the rear end there are two Allen head plugs one right at the rear just above the bolts this is the fill plug and to the right and lower this is the drain plug. and if you are referring to Manual Trans there are two like bolt head plugs one directly on the bottom near the rear is the drain and 3 inches forward on the passenger side up 3 inches is the other which is the fill. it just needs filled until it runs out the top fill hole about 1.9 liters fluid type is MTF LT1

you have a GM 4l30e transmission. sealed. replace the filter and fluid.

could be a solenoid problem as well, but go for the filter and fluid 1st.

I had the same problem on the rear door of my 1998 528i and it was the door actuator that had gone bad. I had to take the rear seat out to get the door panel off. Once I had the door panel off it was not that difficult to replace the door actuator.

you need a cable kit replacement. 25 bucks.

google: 1997 BMW 528i regulator repair kit. 97's and 98 are the same, 99's are diff. the same clip breaks in all of them. this guy has invented a permanent fix for it. same work repairing as replacing, only difference is that after repairing it, it wont break again!

You might want to check the outside ambient temperature sensor, located in the right front wheel well, when these become damaged, the dash temp reading might say somewhere around -44degF if this is the case replace the sensor and things should be okay.

To put the original back in just hope the harness behind the radio wasant cut into. If its not it should just plug right in and mount back up in the stock location.

as far as the cd changer. if you would want to add one. you would need to find the changer, harness and headunit from a model with one.

bad solenoid on the starter,,,,,,,stripped flywheel teeth

located in the fuse panel... which i'm told on bmw's is in the trunk... does your radio work
