ZF6HP26 Metal or Plastic Sump

Hi everyone

I am planning on doing a gearbox fluid change in the next few weeks, I will be using ZF Lifeguard 6 and replacing the Mechatronic sleeve.

So a simple quick question, Should I use a metal or plastic sump?

Your best to use a metal sump and seperate replaceable filter element for future servicing. There are a heap of oils manufacturer rated for ZF6HP available that work every bit as good as lifeguard 6 and cost 1/10th the price ... No idea what country your in?


You can do a proper flush by cutting off the stem that feeds up into the transmission (from old pan / filter you remove) adding some tube to it into a tub of fresh oil and run engine for a few seconds ... you need a good drain pan but is all easily done using cheap plastic tubs

Metal sumps are notorious for leaking

Stick with an OEM plastic version Thumbs Up

Stick with the plastic version, cheap enough to change out again if you ever service the gearbox again.

Sorry but if you have fitted a metal sump as used stock by bmw and ford on the same transmission and it is leaking you have done something wrong!

You can (if you like) get a special rubberised type if your for whatever reason unable to prevent leaks with the paper type gasket.. they (the paper type) imo should be nipped up after a few heat cycles

Its common knowledge the metal pan is an upgrade and more durable & that a plastic pan really should not have been fitted to a off road vehicle ...Also better heat transfer ... then you replace the filter only next service and all other services then on for $15... Anyway at least people are servicing their transmissions Wink

I fitted a metal pan and separate filter 12 months ago. No issues at all. (I did use genuine Lifeguard 6)

Metal seemed logical for an exposed gearbox sump on a 4x4. L322 3.6 TDV8 Vogue. 07MY

Appreciate all comments so far, but I make it 2 all, I was hoping for a more decisive response....

Just to keep the discussion going I thought I would add what I am thinking behind the question.

My car has done 111,000 miles so it deserves the best treatment hence my decision to use ZF lifeguard. I intend to do some off road work along with some greenlaning but nothing extreme just a bit of fun. I am assuming that another fluid change will be after 50k miles by which time it is unlikely I will still have the car.

So has anybody broken a plastic sump?
As far as I know the steel sump is only a few mm thick so does it actually provide any better protection?

It might be worth mentioning that a mechatronic rebuild was done in 2017 at 98,500 miles but the original plastic sump was refitted with new fluid. So the filter was not changed hence my reason for a fluid and filter change.

Does that change what you guys think?

Thanks

I think whoever changed your fluid and not the filter / sump was a clown Smile

Haha, Anyway no i have not heard anyone on here breaking a plastic sump however i do believe a few discovery owners have as they tend to do more adventurers offroading than the L322 does... the metal sumps are thin but standard equipment on many 4x4 fords it seems and if you tore thru a metal one i think the plastic one would be long gone beforehand. For me it was about re servicing as i will be doing a few more services yet (one in the next few weeks again) and only having to buy a cheap inexpensive replacement filter as well as the durability and other benefits of a steel sump imo

Best of luck, the ZF boxes are very good units and looked after should do hundreds of thousands of kilometers with ease 2010 3.6TDV8 Autobiography

I changed to a Britpart supplied metal sump during a gearbox oil change. It has the advantage of cooling fins on the understand and, more importantly, the filter is separate.

I have switched to metal pan as well when I serviced the ZF6 on my TDV8. It came with different bolts as well due to different length used on the plastic pan. The thread holes needed cleaning out so that the new (shorter) bolts could be torqued up properly and evenly. They tended to thread in further than the original bolts used, so you can imagine some of the grit build up on the unused portion of thread which is exposed on the top of the box.

Dave what oil have you been using, if not Lifeguard 6? I note you are in Australia (likewise for me).

Hey Dave,
Thanks for the update. That is good to know before I do the next full flush on the transmission.
Do you have any details on your provent install? I'd be interested to see it and what kind of improvement it made to misting up the intake with oil fumes.
Cheers,
Michael

You've probably already seen you can get 20L of that oil for about $180... plenty for a flush.Repco currently have it on special in 4 liter botles for $37 Cool , I cut the tube off the original plastic sump and with some hose and tubs make my own flushing device and let the transmission suck up and spit out about 4 liters to flush before re filling which helps clear the oil in the torque converter giving you a far better oil change.... sorry i might have mentioned this before, Anyway I've still got half the 20 liter drum left and about t do another change now that I've put about 80 thousand k's on it since


Re the provent i can say that after 10.000 Ks it has caught about 80ml of oil which says allot for the separator already built into the engine which was what i expected .... if it was some garbage jap ute that figure could bet 500ml of oil from what i read on various other sites. I haven't had the hoses off to check for oil in the manifold etc but i will do very soon .. either way i think its as good as its going to get with the can end egr blanked off ..... The thing that really stands out to me is thinking that the oil i can see the provent has caught would have gone thru my intercooler etc then engine... not cool

I feel it is very efficient (Chinese provent) ... ill remove the outlet hose and check it for oil to get a better idea and grab some pics 2010 3.6TDV8 Autobiography

Unfortunately I turfed the plastic pan when I fitted a steel pan. Sounds like a good way to flush the old lube out. I might be able to use part of the old filter that is in there now.
If you have some pics of how you installed the catch can, I'd love to see that too. Have been wondering how to hook one up. The factory unit is buried in the valley of the V8. Have Pam's my email addy is it's easier to share pics.

Cheers,
M
