Dispatch 2014 2.0 HDI 6 speed gearbox oil capasity

[bitsas004]

Hello, I tried looking but find it hard to find how much oil should i put in my 6speed gearbox? its a 2014 2.0 HDI dispatch, should 2 liters be alright ? thank you

I assume you are referring to a manual 6 speed box.

The same quantity of oil removed should be replaced. But if you have drained it, then the following is true for the ML6C Gearbox:

Quantity of Oil after Draining:

DW Engines
Gearbox Casing with fins, 1.9L
Gearbox Casing without fins, 2.6L

So you have to determine the type of gearbox casing first or you may over or underfill it.

The above assumes the gearbox has not been overhauled i.e. dismantled, otherwise the oil quantities are:

2.2L with fins
2.9L without fins

yes its 6 speed manual. Right so there is with fins and without fins for 2.0 HDI 6 speed. Wonder whats the difference between the two gearboxes both being 6speed?

It's hard to be specific as there are different versions of these, but earlier boxes from 2006 had the following

• Ribbed gearbox casing for improvement of the lubrication and lowering of the oil temperature
• Discontinuation of the output shaft greasing filler tube
• Reduction of the oil capacity
• Engraving of the oil capacity below the sequence number on the differential housing (From 21/03/2006)

However, I understand these may of gone through further updates for later models including and apart from the fins, a new clutch housing, reinforced 5-6 hub, transmission torque differences and changes to the hydraulic concentric clutch stop.

It really depends on the gearbox implementation, build date and vehicle application.

Alright many thanks ordered 2l of TOTAL 8 gear oil now just getting under and replacing, thank you

I’ve got to refill my ML6C gearbox, too. So, even if other changes aren’t present such as direct-acting concentric hydraulic release bearing instead of hydraulically operated fork, the ribs on the box are definitive for oil capacity?

This is the end of my transmission, are those the mentioned ribs?

I lost at least 300ml+ when I accidentally pulled a driveshaft out and then drained 2.1 litres out, so I’m assuming when the clutch was changed a few years back, this capacity confusion caused the mechanic to overfill the box?

Pop your VIN up so I can check the exact gearbox type.

Thanks, VIN is VF3**************[VIN obfuscated, can be read by forum staff]

Ok, so confirmed you have the 'reinforced' ML6C (the ML6C/R), on your 407 so:

ML6C/R	Oil capacity
Drain and refill	1,9 litre
After overhaul	2,2 litres

Thanks, that puts my mind at rest. Must’ve been overfilled before. I didn’t want to risk putting 1.9l in and destroying the box if it actually needed 2.6l.

Ironically, since I drained a total of 2.1 litres, I didn’t actually need to do anything after accidentally popping out the driveshaft. Oh well, it’ll benefit from the new oil I expect.

Thanks again
