There are dozens of vacuum lines on that car. Any one of them is probably
become disconnected or had the rubber connector split or something. I had to
replace a couple of connectors before Craig got it. It's probably got very

There are dozens of vacuum lines on that car. Any one of them is probably
become disconnected or had the rubber connector split or something. I had to
replace a couple of connectors before Craig got it. It's probably got very

There is a vacuum modulator on the drivers side of the tranny, slightly
towards the front, IIRC. Check the tubing going to it. Again, IIRC, there
is a rubber cap over the adjustment, which is a spring loaded shaft (small

In our '90 E300D, I have noticed the shifting varies from hard to REALLY
