I've just recently did a full transmission power flush with mitsu and is about to book my car in with them for the rear diff oil change as well. My car has done about 105000km and has the timing belt changed at 100000km

What other oil/s do i need to change? Need to find out so that i can do everything at one go instead of having to find them out 1 at a time.

Thanks!

G'day,
You will need the centre diff and rear diffs done as well. I get the diffs done when I get the transmission flushed. (Every 45000km or less). Cost me around the $270 mark for all 3 fluid changes and a tyre rotation last time. That was at a Mitsubisihi dealer. Surprising they didn't mention it or do it when they did the transmission???

Regards,

I brought this up with SKR the other day and he said it's especially important with the centre diff.

I also do them every 40,000k's.
For memory the centre a rear diff use the same oil.
I saw the oil come out last time and all looked still new but change oit anyway. You can not accurately tell ho much is in there so best to drain and re-fill again.

centre diff is in the gearbox so it shares the tranny fluid.. so youve covered that

whats left is the transfer case/front diff (the are in the same housing so they share oil).. AND the rear diff..

yes transfer/front diff & rear diff use the same oil.. definitly get these changed..

the oil itself is very very cheap as they dont hold much oil at all .. (roughly 600ml for transfer/front diff & roughly 550ml for rear diff)

if you'd like some suggestions on which exact oils to use let me know

Thanks for the info guys! I'll book it in with Mitsu dealer to do the front and rear diff then. I know nuts about changing oils so i'll leave it to the pros. Hmm... maybe my usual mechanic can do it instead of Mitsu?

gremlin, what's a good oil to use for front and rear diff? It doesn't require the specific Mitsu oil like the tranny right?

If you check the Castrol Net-Lube web site and put in the year and model of your car it will give you all the information on what oil to use in the engine, trasmission, diff and transfer case. power steering etc. together with the exact quantities required.

The diff and transfer case hardly use any, .55lt and .65lt at about $9 a lt.

good advice..

if you dont want anything "good" the recommended mineral fill for transfer and rear diff is CASTROL EPX 80W/90

if you want a good sythetic go for CASTROL SAF-XA SAE 75W/140

With so little required synthetic sounds like the go!

Wouldn't the CASTROL SAF-XA SAE 75W/140 be a bit heavy?

Probably wouldn't hurt doing the power steering fluid at the same time, its often overlooked :) also check the last time you had the coolant changed. Like with any other fluid people have their own opinion on coolant but at the end of the day between a 33 and 50 percent mix of Tectaloy or Nulon is probably the best option with the antifreeze/antiboil (antifoam)/anticorrosion built in. Even if you live where it never gets below freezing, you never know where you might travel to next winter. Instead of changing your fluid each time the temperature changes its the best all round solution - it certainly beats replacing damaged parts due to water expanding when frozen... ever seen what a beer bottle does when left in the freezer!

There's no reason other than crash damage for a 3rd gen, even early ones, to require a new radiator with proper preventative maintenance, even on those that function in more extreme climates (rural areas) and have 350,000+ on the clock...

Did the coolant and the brake fluid in my last servicing together with the timing belt. Will check with my mechanic, maybe I'll buy the stuff, pass it on to him and get him to do it instead.

Just had this done but not at a Mitsu Dealer. The mechanic told me that in order to change the filter in the tranny the box must be "split" and pulled apart. Can any one confirm this??

Those gearboxes have an internal filter that doesn't need to be changed mate.

Any benefit to be had by doing this anyway? Transmission isn't in the car atm anyway. Or isn't it a changeable item?

FamilyWagon

I'm sure its a changeable item AL and if your tranny is out then change it for sure.

Who would ever desinged a filtere that cant be changed without splitting open the trannie. Oh hold on, that would be Mitsubishi.

I don't think it's something that ever needs to be changed for the life of the car. Someone correct me if I'm wrong.

If you're handy with mechanical stuff it'll probably take you about 2 hours or so to do. You will need 2 people tho!

2 hrs just to change the OIL FMD. So i take it there is more to it than just dumping the oil and re filling it

We're still talking about transmission oil, right? Engine oil is like a 15 min one man job.

Transmission oil, you can dump it and replace it, but it really should be flushed to get all the old fluid out of the gearbox. No point doing it otherwise.

Yeah still talking about the tranny. So do you flush it with new oil or is there a specific product

Just new oil. But make sure you use Mitsubishi oil.

I thought the 3rd gens were completely devoid of filters on the auto boxes...

Late model 3rd gen auto gearboxes have an internal filter. Check out the workshop manual.

aaah cool. Goes against what I had read previously on the forum. It would be nice if it was a seviceable item, like the 2nd gens.

Actually I shouldn't say that. The earlier 3rd gen auto gearboxes have an external filter. I think maybe the 3L engined ones.

I've actually edited my earlier post to reflect this. Sorry.

I've had a little bit to do with spares for a Mitsu dealer. They have never sold an internal tranny filter the whole time that they had been running the computer system (About 8 years). Says a bit to me about the serviceability of them.

if you have an awd the reason no-one replaces the trans filter is its internally located, to swap the filter they need to seperate the gearbox from the engine to remove it in other words its too expensive labour wise. your better off (like i do) servicing the box on regular intervals

That's why our tranny needs need to do a full trans power flush every once in a while to clear up the crap in there and to clear up the filter.
