I have absolutely no idea how he came to that conclusion, or how that is even possible.
A hard shifting trans points to vacuum right away. Then when you couple it with other vac operated accessories malfunctioning (or a high idle in a gas engine), usually broken lines, worn actuators, or rotten connectors are smack in the middle of your cross-hairs.
Your best friend in old MB vacuum diag is a Mity-vac. You can do some down and dirty simple diag with just your mouth and some golf tees, but a Mity-vac is really nice to have and makes it so much easier to check out the whole vac system.
I'm glad your transmission is shifting nicely and your head rests are functional, but I do not accept your technician's explanation at all. Maybe he plugged a loose line back into place and just didn't want to mention it because it was such an easy fix?
