where to pour transmission fluid
okay guys, i did a radiator change on my car, but alot of transmission fluid leaked out, im pretty sure i know where to pour the transmission fluid, but i want to be 100% sure
is it the plug that says " MB workshop only"? i have a 02 c230 kompressor so here is what im trying to figure out
1) where to pour the transmission fluid
2) is the drain plug a hex key located right behind the drain plug for the oil?
3) how much transmission fluid do i pour in?
p.s i already did a search and i couldent find anything, thanks for reading, please help!

The plug is that hard to remove (you need to break it, and push out a plastic pin) because they don't want you to add fluid to the transmission.
It is a very special formula, designed to work with the friction material in the transmission as a system. It is not readily available through the aftermarket.
You need an expensive dipstick to measure the amount of fluid in the transmission, and overfilling the box can have dire consquences to your wallet. (although your pants will fit better because there will be nothing left to bulge the rear pocket.)
A radiator change always throws up a red flag. There were radiators from Valeo that had the nasty habit of mixing antifreeze into the transmission fluid. You might consider a glycol test to determine if your transmission is contaminated. Check your VIN at the dealer to see if your car is one of those affected.
I am personally hesitant to add new transmission fluid to old. If you are within 20K of 150K, you might consider having the box serviced, with new fluid, filter, and inspection.

Standing facing the front, it's on the left in the back.
You may have to pry a red plastic piece off the cap (it breaks off)
then you can add the fluid, but as pointed out
you need a special dipstick that costs about 50-75 bucks.
Also as pointed out it may be a good time to fully flush the system depending on your reasons for replacing the rad, and the total mileage on the car.
My tranny started acting up around 120K miles, shifting funny, slipping etc.
but a complete flush seems to have breathed new life into it.
