Help Hi there,i have a 2001 bmw 740i,i want to change my transmission fluid and filter,i cant see the dip stick in the engine like for checking the oil level,how do i do it? please help.My e-mail adress is [email protected]

First check transmission dip stick for correct fluid level. Next schedule a transmission filter change. This should have been done at 60,000miles

TRANSMISSION DONT HAVE DIP STICK,YOU HAVE A CHECK PLUG LOCATED UNDER TRANSMISSION NEAR THE PAN ADJACENT TO THE ENGINE OIL DRAIN PLUG.CHECK PLUG IS A METRIC 11M OR 12M METRIC BOLT.TO CHECK FLUID CAR HAS TO BE LEVEL AND ENGINE RUNNING.WHEN YOU REMOVE CHECK PLUG, IF FLUID POUR OUT YOU HAVE TOO MUCH TRANSMISSION FLUID IN TRANSMISSION, IF FLUID SLOW DRIP YOU HAVE ENOUGH FLUID IN TRANSMISSION, IF NO FLUID DONT DRIP OUT WHEN CHECK PLUG REMOVED,ADD A PINT OF TRANSMISSION FLUID AT A TIME.YOU POUR FLUID AT TOP OF TRANSMISSION UNDER THE HOOD,YOU WILL SEE A RED VENT FILL CAP, REMOVE CAP, YOU NEED A VERY LONG FUNNEL TO POUR TRANSMISSION FLUID IN THE TRANSMISSION. IF YOU HAVE TRANSMISSION SHIFTING OR SLIPPING PROBLEMS,MOST TIME TRANSMISSION DUE FOR FILTER AND FLUID CHANGE IF YOU AT THE 60000 MILES TO 120000 MILES TIME FOR FLUID AND FILTER CHANGE.

SEEMS LIKE TRANSMISSION FLUID LOW.TRANSMISSION SLIPPING TRYING TO GO IN DRIVE.CHECK TRANSMISSION FLUID LEVEL. IF LOW ADD FLUID UNTIL YOU REACH FULL MARK ON TRANSMISSION DIP STICK. WITH ENGINE RUNNING A IN OPERATING TEMPERATURE.IF FLUID LEVEL OKAY.CHANGE TRANSMISSION FLUID AND FILTER IF YOU HAVE NOT CHANGED IN A LONG WHILE.A DIRTY STOPPED UP FILTER WILL CAUSE TRANSMISSION TO SLIP.CANT PICK UP FLUID.

SOUND LIKE TRANSMISSION FLUID LOW OR YOU NEED A TRANSMISSION FLUID AND FILTER CHANGE.THE 4T40E OR 4T45E IF YOU DONT SEE TRANSMISSION DIP STICK.BEST TO DO A FILTER AND FLUID CHANGE.YOU NEED 7 QUARTS OF TRANSMISSION FLUID A NEW TRANSMISSION FILTER AND PAN GASKET.I WOULD BUY FILTER AND PAN GASKET AT DEALERSHIP.YOU NEED A LARGE DRAIN PAN TO CATCH TRANSMISSION FLUID.IF YOU HAVE A TRANSMISSION DIP STICK. BEFORE YOU FIRST BEFORE STARTING THE ENGINE CHECK TRANSMISSION FLUID LEVEL ON DIP STICK.SHOULD BE ON THE FULL MARK.IF NOT ADD FLUID TO FULL MARK.THEN CRANK VECHICLE LET IDLE UNTIL ENGINE HOT OPERATION TEMPERATURE ABOUT 10 MINUTES.THEN APPLY BRAKE PEDAL.THEN SLOWLY SHIFT TRANSMISSION SHIFTER THROUGH ALL GEARS 2 TIMES.THEN PUT TRANSMISSION IN PARK.CHECK TRANSMISSION FLUID LEVEL.IF NOT AT FULL MARK ADD TRANSMISSION FLUID UNTIL LEVEL CORRECT.

CHECK TRANSMISSION FLUID SOUND LIKE VECHICLE SLIPPING DUE TO LACK OF FLUID. CHECK TRANSMISSION FLUID ON DIP STICK. WHILE ENGINE COLD FLUID LEVEL ON DIP STICK SHOULD FULL MARK.CRANK ENGINE LET VECHICLE IDLE TO WARM.THEN HOLD FOOT ON BRAKE SHIFT THROUGH ALL GEARS FEW TIMES CHECK TRANSMISSION FLUID LEVEL IF LOW ADD FLUID UNTIL YOU GET TO FULL MARK.IF YOU HAVE THE TRANSMISSION WITH NO DIP STICK.YOU NEED TO CHANGE TRANSMISSION FLUID + FILTER. YOU NEED 7 QUARTS OF TRANSMISSION FLUID.BUY DEALERSHIP TRANSMISSION PAN GASKET ITS THICKER MADE DIFFERENT WONT LEAK FLUID. THE TRANSMISSION GASKETS AT AUTO PARTS STORES TOO THIN LEAK FLUID BAD.

I would definitly try replacing the oil, also make sure nothing is loose and have the front end and the suspension checked also.

There is not a nut on the transmission oil pan like what you find on an oil pan. You can either take your Van to a auto service department and get a super transmission flush (about $60-$80) which I do not recommend, as they do not change out the filter or gasket. OR:
Remove the 10-mm bolts on the pan, and change the fluid, filter and gasket yourself. Be careful as that pan is filled with fluid and will drop and splash quickly. I use a large drip pan to catch all the fluid. Add fluid slowly using a funnel, poured into the tube where the dip stick is in. When it is surely on the dip stick, I start the engine and let is circulate a few minutes. Then check the level and add more. When the engine is at normal operating temperature, I aim for near that top notch on the dip stick. Do NOT Overfill!
41TE (4-speed) has 9.1 quarts. 31TH (3-speed) has 8.5 quarts.
HINTS:
Make sure you clean both the pan, and pan-to-gasket area.(I use acetone) as well as the gasket-to-transmission area before installing the new gasket.
Tighten the pan bolts to 15 ft-lbs.
Filter to valve body srews (if equipped) 45 in-lbs.
Good Luck and let me know if this helped!

Check the Level of the transmission fluid by pulling the Transmission dip stick. The colour of the dip stick is most likely red in colour and you need to check it with the car's engine running and hot. Pull the dip stick out clean it off and check it again. always check the second reading. 
To fill the transmission, you need to fill it through the Transmission dip stick tube. Yes your going to need a thin funnel and good luck. Do not over fill the transmission. over filling will cause damage to the transmission. 
Best thing is, if you have not done a transmission oil and filter change. Have it done at a Transmission shop and you'll know that the transmission level is fine and have them show you have to check and fill the Transmission. As time goes by and mileage get's high, the fluid will get contaminated and the filter plugged up which would in turn cause a transmission failure.
Good luck and hope this helps. Oh and the type of transmission fluid should be in your manuel or stamped on the dip stick.

Your transmission is sealed and has no dip stick, checking the fluid level properly involves using a factory scan tool.

the transmission filter on a 4 cylinder is on the driver side in the engine compartment. it looks like a oil filter right behind the transmission dip stick. i hope this helps. and the drain bolt looks just like a bolt u would use to drain the oil so be careful
