Hi folks, time for a service, but how much and whats the best oil to use in my 1993 w124 e320 estate auto box???? I will also be changing the filter and i suppose that will make a difference in the quantities. Also best engine oil to use????? That will also be getting a new filter.

Many thanks in advance

Hi, how many litres do I need to buy?

Hello Nick, or anybody please,
Is this "Electric oil" the A000 989 92 03 oil recommended by MB on datasheet 236.6 or should the 722.5 early 5-speed box be treated as a 'lock-up' box for fluid specification?
My gearbox is good at the moment and I'd like to keep it that way!
thanks,

Ok, got there in the end: My dealer says use A0009899203 (datasheet 236.6) for the 722.5 5-speed autobox but Bolide's 'electric' oil is for the 722.6 'electric' gearbox (not 'lock-up' Doh!) which is given as A0019892303 or A0019892103 on datasheet 236.10, but should really be A001989210310...
I'll go with Bolide's advice.

Is Dextron III also OK on the 4 speed box??

The reason I ask is on a previous E300 estate of mine, the service sheets from the main dealer had Dextron III listed at the 36,000 intervals not Dextron II.

I have always used Dexron II or III on all my cars equipped with 722.3xx series transmissions. No bad effects noticed in 10+ years of ownership. Dexron III is an improvement on II and is backwards compatible.

Your 4 speed box will be a 722.3xx series gearbox, check your datacard for the gearbox number it will begin with 722.3

My 1993 E300 diesel estate has a 722.4 auto gearbox (4 speed), not a 722.3.

Dexron III is the appropriate fluid for a 722.4 transmission as well, AFAIK it's 722.6 onwards when the MB electric oil (which I read is Dexron III plus some additives) is required.
