Where is the transmission dip stick located for the 2002 525i bmw? makes a noise when car is in gear drive or reverse, but not in park or neutral

no such animal

Right behind the air box on the 2.4L engine. Note that this model car requires that the engine is off when checking the stick (unlike most cars). The procedure is to first get the engine up to operating termperature then put the car in park, engage the emergency brake, then put the car in drive low, drive 2, neutral, reverse then park. Shut car off then check transmission fluid level. Source - 2010 Chrysler Sebring owner's manual.

You can check the fluid level of a transmission only while the motor is running while in park or neutral (wheels blocked). Remove the rear dip stick (transmission) and wipe it with a rag, reinsert it completely. Repeat the procedure and note the level, which should be between or in the hash marks (towards the end of dip stick) and add accordingly.
If the level is okay you will have to check with transmission shops and the Ford dealer for quotes ( and check on Google ). The problem you have is either a transmission or computer problem.

check the linkages from gear stick to gear box may be loose.

if the car is a auto matic start the car in park with the parking break on. under the hood you will see to dip sticks. one should be black "oil" the other yellow Transmission stick. with the car running pull the dip stick out wip off any oil on the stick. reinstall all the way pull it out again, you should have either 2 dots aproxmaintley 1" spread the top dot is where the trans mission fluied needs to be. if it is barley on the stick go to your local parts store ask what type of transmission it uses and buy a couple of quarts probley about 12.00 also get a tran. funnel to add the fluied. put a little at a time and check the stick untial it is on the top mark about2.5" from bottom of the stick. also if the fluied is not a redish color, have it changed. good luck

have you checked the transmissions fluid level, need to check it with the car running in park or neutral, on level ground. If its in neutral make sure the parking brakes are applied and the tires chucked to secure the vehicle and prevent rolling. Locate the dip stick for the transmission pull it out whipe it clean, then re insert it into the dip stick tube until it is fully seated, pull the dip stick out and look at the markings it should read more than half on the hot side.

Have the car on, in park, emergency brake on. Under the hood, red dip stick. From line to line should be 1qt. This is best done when the cars warm. Add until the 2nd line. Get in your car, hold the brake, slowly put it in reverse, neutral, drive, 3,2,1 then 2,3, drive, neutral, reverse, park. Repeat a couple times to move the oil around, and you're good to go.

Make sure your transmission fluid is fully topped up. If the transmission has to speed to build up fluid pressure there will be jolt as the drive is engaged from neutral. Make sure you fill up with the right fluid (use the transmission dip stick tube as the fill point). Also when measuring transmission fluid level have the engine running in 'park'.

Check the gear box oil level....I'm thinking that you have a auto box....this should be done on level ground and with the engine running at idle speed....To check level correctly place your foot onto the brake hard and also select the parking brake....With the engine running, move the selector lever from park into reverse and then to neutral then to 'D', followed by the lower range gears and then moving up to 'D', and then to neutral again and then to reverse and back to neutral....Leave each position engaged for about one second....Leaving the engine running and the park brake engaged check that the gear box oil is at the correct level....It should be between the marks indicated on the red topped dip stick....When filling with Automatic Transmission Fluid (ATF) through the same tube where dip stick is located the engine should also be running and care taken not to over fill....Once at the correct level the vehicle should behave normally.

Readjust the band, I have ran into this same problem with another C-4.Found the reverse spool valve was sticking in the valve body. Hopes this helps.
