Ask ACLex maybe !

I'm sure he will be able to give an authoritative answer to this conundrum for you.

Just as a word of caution before you use the "Castrol compatible", castrols own website says their atf's are NOT suitable and to refer to manufacturer.

Why not see if they will do it cheaper if you supply your own oil, might be worth a try.

Sorry I'm not being much help here almost feel like saying "It's in the sand!"

For what it's worth Floggit, and I am certainly no expert here, this is the way I would be viewing this situation if I were in the same position as yourself;

The only oil that has come recommended to use, and so far without any negative feedback, seems to be Toyota's own Type IV transmission fluid. I would go ahead and INSIST on this, full stop.

As for the method of replacement, the only one so far recommended on this particular thread without any fore-seeable(spelling?) problems seems to be to replace it at 2/3 litres at a time with a sort of 'run in' period of your own discretion. This has worked very well for others in the past without causing any problems.

As I have previously said, this is the method I shall use if/when the need should arise. By doing it in this way I cannot see how any complications should arise. The process may take a little longer to complete which is the only drawback I can see.

I know there is no definite answer here but I hope it may help, slightly.

HI

As I was the the thread that reccommended the 3 litre package let me reiterate the method and time scale.I used a marine engine 12volt electric oil extraction pump that I used to distribute in Europe for an American manufacturer.Its about the size of a tin of beans and connects to the Battery for power,originally designed to connect permanantly to the sump plug and left in situ on marine engines.

It also operates perfectly well by inserting a plastic tube down the dipstick access tube.

It moves transmission fluid at a gallon a minute so taking it out is a relativly quick exercise .When I mentioned a run round the block I meant just that not a trip to Penzance,

alternativly you could just sit on the drive and move the gearstick through the range this will pump the oil through the box sufficient for the exercise.To sum up it took me about an hour to do the 15 litre gradual exchange of the transmission oil.

Before anybody asks the pumps are no longer available but the marine engine oil extraction vaccum pump supplied at chandlers and Marinas will also do the job.

Fuel filters exist to prevent any detritus whatsoever from entering the pump. That could be from corrosion, through the filler nozzle, whatever. Some filters also remove water from the fuel.

But fuel tanks drain from the bottom, so how anything collects on the base of the tank I'm not sure.

The majority of solid impurities will sink to the bottom of most liquids which is how they tend to collect on the base of the tank.

Hi guys, yep i take on board whats said about a gradual change but this only works if your changing it yourself , cant really expect a garage to do this procedure.

On a positive note ive found a local specialist who told me they use the correct toyota fluid, change the gakset and filter and inspect and clean the magnets . They use a vac pump. They were the first garage to tell me the atf fluid is expensive and must be toyota , so they seem to be on the ball.

I think im going to book it in with them . It really is just for peace of mind as the oil is very brown lol.

Thanks for everyones input and if i was mechanically minded and had the tools id be doin it myself.

Will post again when job done.

Thanks steve

Hopefully you seem as if you have found a place who know what they are doing.
