Halfords sell a 5L can of I think Comma Dexron iii. Cost me £12.50 with a trade card. i think normal price is about £15. Works out a lot cheaper than the little 1L bottles but then you need a decent funnel as the 5L doesn't come with a spout.

Good to know, I was just going to check ebay prices for a 5l as well and I have 0.5l poring cans at work :).

 

How would I go about doing a full gearbox oil flush and refill??

Christ Wilson did a full atf flush and filter change on my autobox and it has been so much smoother since, money well spent :)

 

Ahh maybe I will pm him, I know the filter is in the sump as someone said above should be easy enough.

 

Just the next part, the full flush and refill?

I'm thinking disconnect the igniter, turn the car over in 'P' or 'N' with the oil out let line disconnected? Could be bad though turning the gears dry.

Dipstick hole will be fine as from manual.

 

In the manual it has nothing on a full flush so 2 ltr drain and refills is the way to go for me, new Toyota T-IV ATF has sufficient additives to maintain this coating and also enough co-polymers to rekindle the older ATF.

The older ATF is still red anyway, only just gone bpu so needes a maintain!

You could probably take both hoses off the cooler and use one to suck new fluid in and let old one flow out the other. Might be harder to control this way and I'm not sure if it's a safe method but I've heard about somone doing it this way on here I'm sure.
