Where is the trnsmission cap for clk 320 model

Depending on kilos... Ive heard there is an oil filter on the sump.

Also remember the necessary fill volume varies with temperature.

As long as the specification is correct the make would be your preference! Automatic transmission fluids (ATF, Specification 236.1)

On the drivers side of the engine you will see the oil filter housing and an air tube. The power steering reservoir is under the air tube.

brake switch needs replacement.

is your soft top not working it's not the faulty relay, it's control by electronic control unit, it's call soft top control unit, so first do one thing, open boot and have a look, there are one separation lid which is winding like cover, you must have close your boot separation lid buy pulling it out and hang it on hook which is locate both side back in boot, there are two hooks for hookup the separation roller lid,you pull it out and hookup it on two hooks, and close boot then operate roof if still roof not working it's need to be diagnose because there are many sensors and switches are fitted in this system if one switch or sensor not work your roof will not longer be opening and also there are any hydraulic oil leaking or lack of oil in the pump, it will not work, so in this case you must drive your car to the authorized Mercedes workshop who have the right diagnose tool knowledge for this particular car,

In order to check the fluid in the transmission you need the Mercedes Benz dip stick. It's a special tool needed for all the 722.6 transmissions. Best thing is probably to just stop by a Mercedes Independent shop where they can check it real quick. It uses a synthetic based fluid. I always go with the factory fluid.

The microswitch in the trunk is probably failing. Its just a pin switch. Get a new one and install. Its meant to warn you if there is something in the way.

to replace engine oil
with oil filter 8 qts
with out oil filter 7.5 qts

just had the same problem today...there is a small square false door just below the D on the shift plate...the tow guy put a pen into that door and i was able to shift it out of park. now the car won't shift gears as i drive because the car is in 'safe mode'. disconnect the battery to correct. the shifting issue is still unsolved but it appears to be an electrical issue in the transmission but NOT the actual transmission. hope this helps

Hi, Joe here to help,
The ONLY oil you should use is Mercedes transmission oil. As far as how much to put back in, 4 qts if you do it right away, 4.5 qts. if you let it drain a while.
