Yaris Oil Change

[JohnnyD]

Recently while changing the engine oil I drained the oil, by mistake, from the gearbox (about 1-2 pints). On realising my error I then drained from the engine sump plug. I am assuming that gearbox oil is filled also from the engine oil compartment There is no obvious filler cap to top up the gearbox. If I am correct what is the point of having a separate drain on the gearbox? Surely this should empty with the engine oil.

Can anyone confirm this? The gearbox drain is located on the nearside, the oil pouring out towards the front nearside wheel.

Thanks

John

Hi,

the engine oil drain plug is located on the right-hand side (that's what you call near-side, right?) of the car, facing the right-hand side, the gearbox drain plug is located on the left-hand side of the car facing the left-hand side (bottom-side if auto gearbox), the gearbox filler plug is located on the left-hand side of the car facing the front-side of the car and sitting just a tad higher up than the drain plug (through gearbox dipstick tube if auto gearbox).

So, the pressed sheet-metal rectangular thingie is the engine oil sump, the cast "cylinder-dome" shaped thingie is the gearbox.

Engine oil and gearbox oil are separate, and very different for that.

If you really drained 2 pints (+/- 1.1 liter) of oil from your gearbox than it will be either almost empty if you have a SZ-series engine (1.4 liter oil), only about a third left over if you have a NZ-series engine (1.9 liter oil) or just a litlle if you have an auto gearbox (5.9 liter ATF). you will need API GL-4 or GL-5 75W-90 for a manual box or Toyota T-IV ATF (NOT DEXRON) for a auto.

Also don't forget a (new) washer between drain plug and sump.

Cheers, Yves.

Thanks Yves. I should have made clear it is an X reg, 1 litre, manual. My apologies for the confusion about the various locations. The engine sump (and drain) is clear, as you say a rectangular shaped black shiny bit bolted to the bottom of the engine. The drain plug is located at the rear.

The gearbox drain is close to the nearside front wheel (front left of the car). The likely filler looks to be as you say just slightly higher than the drain and is located on the front side of the gearbox, facing forwards (towards the radiator). The filler is therefore slightly higher than the drain (obviously) and at 90 degrees to it. Would you agree?

Thanks for the oil references. I can't be sure just how much oil came out of the gearbox I was guessing. Presumably I refill with the car on level ground pouring in as much as will go (until it starts to overflow from the horizontal filler).

Thanks for your help.

yvvan you seem to kow alot you could come inton some good use round here,

nice of you to help the guy out

[JohnnyD]

Knightrider, you look familiar!. Anyway I understand that gearbox oil needs changing every couple of years. I wonder how many cars are on the road having never had a change? I have to say that I thought the gearbox was lubricated by engine oil. Do most cars have separate oil supplies (for engine and gearbox)?

[yvvan]

HI,

@ John, yes you just fill the gearbox with the car level until it comes out the filler hole, if you use a small bottle of gearbox oil just make a hole in the cap (unscrew it first, gearboxes don't like debris), stick a lenght of clean small flexible tubing in it, stick the other end in the filler hole, turn bottle over, hold it up and no mess.

So nearside is left-hand side then? Sorry about that, I thougt it was right-hand side as that's what you folks sit nearest to?

X-reg? I suppose that each year has it's own letter?

@ knightrider, Thanks, after all, I think that is what this great community is all about.

Yeah TOC is great and that is thanks to the guys who share their technical knowledge.

It is much appreciated.

Toyota T-IV ATF (NOT DEXRON) for a auto.

Ohhh gosh... could anyone tell me what the ATF type that should be used in 1SZ-FE (Model:SCP-10), its a 1L 2001 auto & I just filled her up with Dexron.

Hi,

@ IceHz. Toyota T-IV ATF is what should be used, all recent auto boxes from Toyota require that now.

About the use of Dexron I've heard horror stories and I've heard people who said they didn't notice any difference. I never actually seen one that used Dexron, so this is all just hearsay for me.

Did you do a complete flush (5.6 liter) or just a drain and refill (+/- 2 liter)? I have no idea on how both fluids would behave when intermixed.

Cheers, Yves.

[IceHz]

Hi yvvan... thanks for the reply, yes I did do the complete flush & refilled with D3. I searched through the user manual but couldn't find anything resembling D3 or T-IV it is in japanese.. this is a jap import

I just spoke with my local Mr. T and he says use whatever that is mentioned on the dipstick if not use D3 (dexron) from what I can remember there was no such thing mentioned on the dip... checked it out before doing the flush... will check again later today as I don't have access to the car right now.

from what I understand T-IV is used by specific type of autos (Aisin-Warner slip-controlled lock-up automatic transmissions) if there is a way to identify the auto typ e intalled in the car that would give some clue...

here is a link to Mobil product datasheet about a replaement for T-IV:

Mobil ATF 3309

be back after checking it out....

Cheers

Hi,

@ IceHz. You can check the VIN-plate, on the bottom row of it, it should state on the last part of it (marked TM) what the gearbox is, it will most likely be a U340E/U341E or U440E/U441E box. These require Toyota T-IV ATF (or any other ATF fluid that meet the JWS3309 like the Mobil product you linked to). Aisin is (part?) controlled by Toyota, that's where they get their boxes from.

From what I hear on these boards you Brits must have some pretty good customer oriented Toyota dealers , surely the guy should know better.

Cheers, Yves.

[IceHz]

Yep... got the U440E, also dip says Type T-IV. Will contact Toyota and check out availability, is it safe to drive with the D3 for the moment? just 30-40Km trips & I don't push the car to its limits.

BTW I am not from UK... just from a obscure little tropical island B) to make things worse Toyota doesn't import vitz/yaris here, hope these guys know about the T-IV coz last time they suggested D3

Well thanks a lot yvvan... you just might have saved my A/T and my car for that matter, hate to even think someone tearing her apart to replace the box.

Excellent info I must say

Cheers

Hi,

@ IceHz. I would just try to get hold of Toyota T-IV or an equivalent ATF while using the car with Dexron till you have it, and then do a flush and refill.

Hmmm, little tropical island ... .

Cheers, Yves.

[IceHz]

Thanks yvvan... spoke to Toyota and will be getting the ATF changed next Saturday, they have the T-IV. Will speak to them about getting a english manual for the car while I'm there.

As for car stuff there is very little info (at least toyota) on the manufacturer websites... I would expect atleast a pdf download for the user manuals and access to technical support bulletins. If not for sites like TOC people like us (living in tropical isle's!!!) will be left high & dry where local knowledge on these technologies are very low.

Cheers
