`92 240 Gl station wagon, manual shift. When stationary it is reluctant to
go into 1st gear, clutch is fine, no grinding noises, sometimes it seems to
help to slip it into 2nd, then 1st. All other gears are smooth, AFAIK this
is the original box, and it has > 300k (km) on the clock. Any ideas?
TIA

Tired synchro probably.
Just keep hitting second first and run it another 300km.
(I made a habit of touching second before going into first, if it needs
it or not, back when I first started driving... picked it up from pops I
guess.)

Draining/refilling the transmission oil on my '88 240DL made this same
problem go away. YMMV.

I have an identical problem in my 90 240 wagon (167k mi), and it was
doing it since I bought it 30k miles ago. Any gear above third is
fine, and lots of people who drive my car have difficulty finding
first, they don't expect it to be quite so far over. I was told by my
mechanic that he believe that there is a connecting pin that will
account for this problem, he is hoping that the pin has just gotten
loose and can be easily replaced. But, he also sounds nervous that the
hole that the pin attaches to has grown in size over the years, and it
may be a more difficult job.

I am still trying to save money for the repairs. I will let you know
how it turns out.

I'd probably just swap the gearbox, 240s have been around long enough that
you can get these cheaply. Last time I was at the U-pull yard near me they
had several cars with the M47 5 speed in them, $55 for the gearbox but you
have to yank it yourself.

ooh, just got the linkage pin changed, and it was WORTH IT. The
shifter is much more useable now, still a bit loose when in a gear,
but MUCH easier to shift into first and second gears.

Simon,
I had a mechanic fiddle with my linkage pin (WHAT??!! ;-) ), and it helped,
but didn`t entirely solve the problem.
I also changed the transmission oil as suggested by another poster, but that
didn`t help.
Thanks to all for the help

Just verifying it isn't a dragging clutch - if it helps to shift into second
and then into first even with a couple second dalliance in neutral
inbetween, it definitely isn't the clutch. If the delay in neutral makes it
hard to get into first again the clutch is dragging a wee bit and causing
the grief.

First gear in most gearboxes is the most sensitive to lubrication - not sure
why. If the lube level drops the symptoms you describe are usually the main
warning. If the level isn't low the synchro is probably worn. :-(

Overfilling the gearbox (by filling with only the fill side on jackstands)
sometimes helps when first gear gets balky. Additives may also help you put
off the inevitable - Lucas is the name I hear most recommended / least
reviled. And some people swear by Redline tranny lube... never tried it
myself.

If Its like the auto theres a pastic grommet in the hole where the pin goes
through and they wear out .When putting in a new one make sure its been in
hot water first so its plyable
