SO this is a 4 speed manual, I gather.
1. Check/change the trans oil. If someone put hypoid gear oil in
it, it will smell distinctly. If it is like older 4 speeds, it takes
ATF, not gear oil. Gear oil gets very heavy when cold, and the MB
transissions are not made for this. It causes the symptoms you
describe. (input shaft drives the output shaft because the oil is
not slippery enough, causing grinding.
If the clutch was worn out, at the end of adjustment, the pedal
(release) is too high, not too low. I always tried to keep the
release point low to be sure there is plenty of distance to release
the throwout bearing from the clutch fingers. If the pedal gets to
high, then the bearing rides on the fingers. A worn out clutch will
over-rev in high especially when going over bumps.
So now that cooler weather has set in I find that the trans on my
'78 240D (that I finally bought from Dwight) doesn't want to shift
in reverse until the car has been driven some. First thing in the
morning I fire it up and it'll go into reverse (to get out of the
driveway) but theres always a little grinding to do so. Most times I
just start in reverse to avoid the grind but lately its been cold
enough I need to scrape the windshield.
Once I've driven enough for the engine to be warm it'll shift in to
reverse no problem...
The clutch engages very low on the pedal throw compared with other
MBs I've driven. Dwight had mentioned his mechanic said the car
needed a clutch but I can't see why other than *maybe* it doesn't
disengage well...
Does the '78 have the same trans as my '83? Might be worth pulling
the trans from my '83 which has a replacement clutch with only
~50,000 miles on it.
