1984 300d tranny
I drive a 1984 300d with a turbo mercedes benz


My transmission stopped working suddenly after working fine.
I noticed that there was a leak at the location where the pipe for the transmission dip stick (the fill pipe) and the transmission case.
I looked down to where the pipe connects on to the case and did not see a nut or bolt of any kind. I am wondering how the transmission fill pipe is connected to the housing, is it a press fit?
How can i fix the leak?

I also saw a loose rubber hose (~6 mm diameter) hanging out right above the transmission it looks like a vacuum hose. Does anyone know where that goes?

Is there a good place to look for diagrams of transmission assemblies for a 1984 300D

You need to get underneath the car and look along about the middle of the tranny on the drivers side. You should see a round "modulator" there with a nozzle for a vacuum line or a vacuum line attached. If you look real close at the end of the tranny dipstick you will see an allen head fastener holding a flange that keeps the tube in place. Remove the allen head fastener and the dipstick tube will pull out. Replace the o-ring underneath the flange.
