Gl76/27 G-5 is a different design but has the same torque input. The 76 stands for shaft spacing
If you google research all Getrag gearboxes have this similar designation referring to the input torque. in some instances it may be in ft lbs, as is the case for dodge cummins. I am not completely sure but i dont think they would use a 360nm rated box in a cummins truck. With Getrag Europe though the designation is for Nm.

Yours is a 717.400 Gl275 is the Getrag designation. There should be a complete number with it should go like 717.400xxxxxx IIRC. it is in the usual place along with the other 123 number. it will be stamped somewhere on a the lower part of the transmission. I will have to check to be sure where.

I do have a repair manual available for the 717.42x gl275, As well as the Gl76/27 G5 (717.43x) Its for the G wagon version. The only difference from the 717.40x is the output flange. It covers everything. Some photos are grainy though. You can buy it from 4x4abc for 50$ but I'll do it for $20 for my time. Or if a mod can let me post it here on the site I will do it free. It is large file type. Copyright issues may arise though. 4x4abc sells it and they definitely don't have the rights. It is so obscure it should not be an issue.

A0102503403 or reconditioned A010250340380 for clutch disk. Everything else "should" be the same as 4-speed.

See 84 5 speed 300D --Clutch is Screeching Loudly when Engaged. - Page 3 - Mercedes-Benz Forum

The other one is a U.S. market '85 turbo sedan with Otto matic trans & turbo.
Question 1) I asked the local driveline builder how they'd address getting the engine balance right, and they said that if I brought both the flexplate/torque converter and the Flywheel and clutch assembly, that they just balance the flywheel assembly to match the flexplate assembly, and that would work. It sounds logical. Does this make sense? The company:
www.butler-macmaster.com/
has a good reputation around here.

Question 2) The transmission nameplate reads: Original Mercedes Benz
Teil Nr: 123 260 2001
Aggregat Nr. /80 024716 (the "7" may be a "Z")

Before the car got wrecked, the transmission was making a funny "clanking" noise only while in neutral with the clutch ENGAGED. It sounds kind of like a bad throw out bearing, except that with the clutch engaged the bearing isn't turning... I've been told that the problem is something about a shaft that runs in a bored bushing in the aluminum case, and that the fix is to bore it out and install a bearing.
Is anyone familiar with this gearbox or this problem?
Are parts available? either from Mercedes or Getrag?
Can anyone recommend a transmission guy who's familiar with these?
My plan is to take the car off the road this winter, and I wouldn't be in a screeching hurry to turn the job around.

Question #3: I hate the U.S. car's "not so Smart" climate control, and have toyed with transplanting the manual rig out of the Euro car. I've been warned that this involves tearing the whole dashboard out, and is a pain in the neck. Anyone done it?

Thanks for any advice.

Hi seoseo,

Hope you got your problems fixed.

Do you recall by chance if your 85 300d and 84 Euro 300 5speed forward driveshafts were the same length? Also, were the crossmembers the same?

I know its been a year since you posted, hope you see this. Thanks!

Heres a post I have in my files. Two of my 5 spd cars had this problem.

"I just got this email in response to an inquiry that I sent to "Metric
Motors" about working on transmissions. I honestly can't remember how I
found them. But anyway, this sounds like a pretty definitive answer:

My note to them was as follows:

"I understand that you specialize in BMW, but hope you might have
information on this problem. I have a Euro-market Mercedes 300d, 5 cyl
diesel, natural aspirated, with 5 speed Getrag OD transmission. Transmission
works fine, but makes an irritating clanking rattle at idle WITH THE CLUTCH
ENGAGED. I seem to recall reading that Porsche 944\'s had a problem like
this with a Getrag 5-speed.

Questions:

1) Are you familiar with this transmission? (I don\'t have a model number,
but could get one.) Is this a familiar problem?

2) Can you get parts for Getrags of this age?

3) Would you be willing to repair it? I live in Maine, but it\'s light
enough to ship.

4) If the answer is \"no\" to #3, can you recommend a shop
(hopefully east coast) that is familiar with these.

Thanks very much."

Their response:

"Hello SEO,

What you are describing is a Reverse Idler Gear - also know as an Idler Gear
or Auxiliary Gear.

It's a common problem with Getrag Transmission. Among BMW's, the 260, 240
and 280 and 250 all share this same problem. From the factory, there is a
shaft in the Tranny, that supports the Reverse Idler Gear and it is NOT
shimmed properly against the case (too much clearance.)

Somewhere after 125,000 to 150,000 miles and/or without regular oil changes,
the rattle develops. To fix it (in a BMW anyway), the entire transmission
must be disassembled and reshimmed. Your transmission won't break or prevent
you from getting home but it is annoying.

All that said, we do occasionally receive inquiries like yours - about
working on Getrags for other car models.

Sadly, it is not that simple. Our expertise is only with BMWs so we won't be
able to do the repair for you.

Also, we really don't know of a shop that can.

Sincerely, Teddy Rowe"
