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

My tranny was working fine till it recently stopped working suddenly

I took care of the leak in the transmission (thanks to this forum)

I found a loose hose hanging out on top of the tranny. The hose is ~6mm dia. I noticed the short tube (~2" long, ~10mm outer dia, ~6mm inner dia) that the vacuum hose fits into on the end of the vacuum hose. In other words i cant use that short length tube to find the where the vacuum hose fits into.

I looked on the driver side of the tranny near the bottom of the oil filter and saw a hole that could be a match but i did not see anything else.

Is the modulator closer to the front of the vehicle than the pan.

thanks

Hmm I'm like a fly to a light with zero reply threads and it is late so I guess the best answer to your question is this:

I doubt there are any vacuum lines on your trans that even if not connected would cause the trans to stop working. The vac lines are used to soften the shifts with these transmissions. The most common MB sudden failure for an auto transmission is the infamous B2B piston . The second suspect would be a pump failure. I am not sure if the B2B problem applies to this year or not. Maybe somebody else has some thoughts on it?

Hello,

Looking at that photograph the modulator is on the driver side/left side of the vehicle...

The great question is as follows...

"...Are the modulator valves always located on the left side of the Mercedes transmissions? Or do some have them located on the right side also..?"

Thanks, inquiring minds want to know...
