Question Getrag 265 in '79 300TD?

Will a Getrag 265 5 speed from an 80's BMW work in a 300TD auto/manual swap? They aren't too expensive or hard to find, they seem to have a good rep. for strength and durability, and the ratios are close to the Merc 5sp. Is this a viable alternative to a 240D 4sp?

NOOOOOOOOO. the Getrag gearbox is not geared for any diesel, it wouldn't even work with a M103 or M104. it revs to high.

there is actually someone on this board, I thing it Lutz, that actualy has mated a bmw transmission with a 617. also that G265 has a removable bellhousing, so it would really make things easy!

really. i would love to see that. (Not that i dont believe it) but my 16V usually shifts at about 4K to 5K RPM. way to high for a 617 to sustain.

What revs too high? A diesel revs too high for a 265 to tolerate? not likely.

My friend, the real problem is that the bellhousing won't mate to the engine (without major adaptation)--the starter bump is on the wrong side.

Otherwise, it would be great, I'm sure. (And I would have done it already, seeing as I have 3 of them sitting on my garage floor and a 300TD with an automatic I am bored by.

no, other way around. the 265 can tolerate extremely high revs for a long period of time, (ask me how i know)

a 617 on the other hand, cant.

That does not make sense to me. The engine does not care if the gearbox was built to rev high. The engine only dumbly provides that power and torque it has. The gearbox only provides mechanical advantage. It would be no disadvantage that I can see to have a gearbox that can do more rpm than you need.

I thought it was Granimal, who adapted a BMW 5 spd. I didn't do a search for the post. I did look throught the Performance section. He also but a turbo on a 240D. As I remember, he cut the bell housings from the BMW and the 240D, and welded them together. I think he was having vibration problems, though. He didn't have it on lok enough to get an MPG rating.
There is another site, where a person took a MB 5 spd from a 190d (?) or such and adapted the parts into a 4 spd casing of a 240d. I haven't looked to see if he put it into a car or not.

Granimal did the 265 bell for his 61x. I was going to tool one but interest is not such that it would be fiscally responsible. gearing is not an issue, just get a different rear end gear. gear spacing may be strange for a diesel and would feel strange but the 5th gear milage gain and lower RPM comfort on the highway is well worth it. I am currently running a 4spd with 2.47 rear. it is exactly the same final drive ratio as the 5 speed with a 3.06, at a fraction of the cost. no off line pep since its like taking off in 2nd all of the time, but these cars were never meant to be drag racers. my last fill I got 34 MPG

This the one you were thinking about? It was a lot of trial and error getting to where it`s about ready.

towards the end of PG2 is where it all finally comes together.

I have a 5 spd out 0f a 86 190 2.3 16V Iam thinking about doing this to.

Cut the bellhousing off a donor (automatic) tranny and install it on the 265.

doesn't matter what side the starter was on.

This I disagree with; what would you consider extremely high revs? My diesel doing 75 seems like a pretty high rev, and I've always been told that a diesel's power band is up high, anyways...

i don't think im being clear, and i may be wrong. the way the 265 is geared is wrong for a low revving engine.

just take my post with a few grains of salt.

A diesel develops its power, generally at a lower rpm than a gasser and our 617 diesels have a max rev of about 4500 compared to most mb gassers of the same era the rpm max is about 6000 rpm.

The diesels are lugging torque monsters, gassers love to wind by comparison.
