Title: Oil for manual gearbox and differential
Post by: EeVeeWee on August 04, 2024, 16:02:04
A question for the specialists of oil in my manual gearbox and rear axle.
Both have completely been disassembled and overhauled, so there is no more fluid in it.
From an oldtimer oil specialist I bought for the gearbox:
Classic ATF A
Automatic Transmission Fluid
GM Type A, Suffix A

and for the differential I bought:
Classic Gear LS 90
Transmission Oil

This I found in the Pagoda SL Group Technical Manual:

Quote
One thing a lot of owners do not know is that the standard Mercedes 4-spd of that era uses automatic transmission fluid, not engine or gear oil. The transmission itself according to my experience and my literature is basically the same unit as used in the 230-S, 250-S, 250-SE, 280-S, 280-SE sedans. Some other models are close but gearing is a little different in the diesel and 4 cylinder sedans of the era.

Are the oil types I choose the right ones?

Yes, ATF for the manual gearbox. Specification MB 236.6 is what’s recommended. For the rear axle, Hypoid gear oil SAE 90 is recommended.

Hi,
the differential oil you bought is for Limited Slip (LS) diffs. Do you have one?

It's a standard rear axle from 1965, I guess not.

OK thank you, so this one should be better for the gearbox?
