Gearbox

Hi
Can anyone tell me how much oil goes into the ZF 5 speed gearbox from Range Rover l322 4.4 2003
Thanks Mike

It doen,t matter the box will fail before you can fill it (sorry) meant as a joke)

I can't find much info online however you can do it the old fashioned way.

#1 put in what comes out make sure its full before you drain btw lol

~#2 i highly doubt it takes more than 10 litres so to be on the safe side i would by 2x 5 litre bottles that way you know you won't be short of fluid.

Hi
have found out it takes 6lts
Thanks Mike

You'll have to have more than that. It's a right dirty job and you'll have to accommodate some spillage
Have you purchased the oil yet ?

Yes but have man with a machine that puts the oil in

I think I'd double check that.

These are the dry capacities for all 24 models of the 5HP24, according to ZF. The Range Rover is the ‘032’ model = 9.70 litres, although Land Rover specify a figure of 9.9 litres for the L322 in RAVE.



The torque converter, valve body assembly and internal hydraulic galleries retain almost half of the fluid during a drain & refill so 6 litres, give or take, is about right for a refill.

P.S. In case you’re interested, the reason the ‘034’ & ‘035’ models have a higher capacity is because they use the larger 280mm torque converter rather than the 260mm unit used in all other models

So it will take a few changes to replace all the fluid.

Assuming 9.7 litres dry capacity & 6.0 litres refill, the proportion of new fluid in the transmission following each drain & refill is:


So changing the fluid 3 times will give you 95% new fluid, but you’ve thrown away 8.8 litres of new fluid in the process

Bit more that that.......

Cheers

You’ve added 3 x 6 litres = 18 litres, thrown away 8.8 litres (3.7 during the 2nd drain and 5.1 during the 3rd) leaving 9.2 litres in the transmission (i.e. 95% of its 9.7 litre capacity).

Phil

Is that 6 litres if you drop the sump and include whats behind the filter as most folk wouldn't do another sump drop after the first drain
