Re: [MBZ] 450SL tranny update, and rough running

Oh yes, that was one of the first things I noticed about the Mercedes
vehicles. They were like a slot car at speed. They felt so stable and
secure as opposed to Detroit iron, which took two hands and white
knuckles to drive over 65 mph.

I think owning this MB was when I first noticed the way the suspension 
changed (or maybe my 69 280SE) --  when I got to around 80mph or so - it

seems to do it in all the MBs I've owned - at high speed the suspension,

like,... changes - it kind of 'hunkers down' and the ride gets
so 
smmoth!  It's an amazing feeling actually - it's like being in a

totally diffferent car.  The pavement strips get virtually silent and
the 
bumps disappear - and the car seems to float down the road.   I suspect
some 
others of you have felt the same thing --

RPMs, but that 1-2 shift chirped the tires when I stomped it!


No way ours will do that.  But it's a '76 smog-boxer.


Ideas?  Oh, I almost forgot -- how many gears does this tranny have?


Ought to be three.  But I'm no expert.  Count the orange pips on
the speedometer, should only be two of them at the redline shift
points.

That's the first thing to try. My '78 started to run rough at idle,
then progressed to rough all the time, then it quit starting all
together.Turned out to be a combination of lots of loose and/or dried
out parts. The rubber seals around the injectors were rock hard,
shrunken, and had to be leaking. Finger loose intake manifold bolts on
one head didn't help any either.
I won't EVEN address the 3 gears in the tranny though -

All German cars are like that, my old Audi Fox did it too.

Man, I miss that car!  Rusted away, still ran great but there were 
holes everywhere...

3, or 13, or something like that.
If the car has been sitting, the injectors are probably spitting instead
of atomizing. The cheapest possible cure I can think of is a bottle of
Chevron Tecron and an Italian Tune-up.

Hi Rich -
   Wow!  I'd forgotten some of the hazards of letting someone else work on 
my cars !!!  Whew!!


About that 4.5 engine - Man!  it's got some power doesn;t it??  I had a 73 
280SEL 4.5 (W108 - still my favorite body style) and it would chirp the 
tires if I hit passing gear at 45MPH - gobs and gobs of torque!  Loved to 
hear that big V-8 purr as we cruised at 75mph.   It would get 13 mpg if it 
was tuned to within an inch of her life - but man oh man it ran great!!

Subject: [MBZ] 450SL tranny update, and rough running



Here is some update about my buddy's '79 450SL that had a bad tranny.
(BTW you are all my friends but you are all jerks too, right wrong and
everything in-between at all times!)  (guns, Bush, what oil to use?)
(there, that ought to start about 500 flame threads and debates on
various topics!)

So anyway, he orders a new tranny from Rusty a few weeks back, has it
delivered to this indy in town that is supposed to be the top deal.
Takes awhile but he gets it installed, works great.  A few days later he
notices tranny fluid dripping and takes it back to the top-notch indy
who says the tranny is bad, leaking at some main seal, gonna need yet
another new one.  So he talks to Rusty or whoever sent the tranny (might
have been both), quotes my buddy another $1100 or whatever to swap yet
another new one in (I guess Rusty or whoever was going to send another
unit down, warranty).  My buddy chokes on that deal and takes it to an
Aamco or some such to get another opinion, some old guy there says he
has done lots of Benzes, knows the deal, will check it out.  This guy
takes down the exhaust system or whatever is in the way, sees that some
doohickey the indy installed on the tranny (from the old one) is
leaking, tightens or seals it or something, and puts it all back
together, $400 for the time to do that, all fine.  So now my buddy is
back and forth trying to get the $400 from the top-notch indy because
their stupidity or poor installation caused that expense, and has found
yet another mech that is reported to be good (this would be about the
4th one now).  He is getting really upset at all these guys trying to
screw him.

Anyway, I drove the car today, it is running a bit rough at idle and low
RPMs, but that 1-2 shift chirped the tires when I stomped it!  That
tranny was flaring and really soft before but is working fine now!  Some
fun!  I thought the rough running might be either/all 1) some bad gas
(it rained a monsoon here last week), 2) needs a tuneup (cap, rotor,
plugs -- the cap looks like it might be time for a change, kinda dirty),
3) maybe something got knocked loose (vacuum hose?) in all the tranny
stuff, 4) something else?

Ideas?  Oh, I almost forgot -- how many gears does this tranny have?
