Auto Transmission Filter

[SiliconAngel]

Andy find out what thread type and seal diameter is - I THINK they just take a standard oil filter, in which case an Amsoil one will be available.

For interest the standard oil filter is M20-1.5 with a seal diameter of 66mm, which is the EA020 filter.

Thanks Trev. This is all something I plan on doing in the next few weeks.
Just trying to build up a collection of oils and parts in preperation for the big day.

Just a thought, the engine oil is pressurised whereas the trans isn't. Perhaps thats why mitsi want to recommend a different filter?

 

[SiliconAngel]

Its a good point Brad, but logic suggests if they use a standard type of oil filter then anything equivalent will do - oil filters are designed to filter particles at a given size and the casing is designed to seal against and withstand a certain pressure - lower pressure shouldn't cause a problem.

That's my theory, anyway - as I don't personally have either an AT nor a filter for such it's not going to affect me if I'm wrong, so you'll really need to do some research to make sure I'm right before taking my advice!

 

[bradc]

they have a bypass though that doesn't open when the oil is below a certain pressure, don't they?

 

[SiliconAngel]

Don't think it works like that Brad - bypass valves are designed to stop a clogged filter from blocking oil flow - basically it's a pressure valve that will open if the pressure against it becomes too great - it's not 'open by default' until the oil pressure reaches a certain level.

Ok, stating the obvious here.

That looks like a complete bitch to get out!

uhh.. isnt the transmission oil pressurised as well?

i was under the impression the oil was pressurised and used to control the clutches/bands to operate the planetary gearset?

 

[bradc]

You can take the dipstick out while the car is running and oil doesn't spray everywhere, so it can't be under much pressure?

 

[Guest]

you can do the same with an engine....

the sump shouldn't be pressurised, if it is, you have issues (your dipstick would shoot out on engine/tranny if it was...)

the pump pushes oil to certain lines to activate different bands/clutches, and then the oil drains back to the sump, similar to an engine.

pass, dunno

Funny thing is after reading this threat I checked my 2001 Leggy and you can see where the filter is supposed to go but there is no filter.

 

[Guest]

anyone know the amount of oil the auto takes?

Just rang Mitsubishi in Bathurst, don't have the filters in stock here, but they reckon there are 15000 in the warehouse! that's a lot of filters!!

about 10l minium to do a full flush

Plus another 5 to replace that left of the highway after the return hose to the AT pops off.

Pops off?
Did you replace the old jubilee clip or just whacked it back on?

Replaced. Clearly it wasn't refitted or tightened well enough however.
All good now.

Yes the facelifts do have them, if you look in your engine bay on top of your gearbox you will see it ...

Yup, this came in handy as I'm at Berwick Mitsubishi spare parts right at this moment... all those years later!
