It's a somewhat complicated vacuum system. Do a search for OM602 vacuum diagram.

A number of us have found that simplifying the vacuum system removes some variables that can be troublesome. See the PDF of essential vacuum routing here: https://www.peachparts.com/shopforum/diesel-discussion/420846-1993-300sd-egr-delete-wastegate-function.html

I've found by testing that most of these things leak at this point, so I would simplify it, waste gate conversion, etc. Get yourself one of those handheld vacuum tester/pumps, and check each thing. you can put a golf tee or bolt in the hose to block it off.

if it's not shifting out of first also check the Bowden cable, and loosen it up if necessary. Check fluid level too.
