Auto Trans Fluid

[Endless]

Just got a quick Q some of you guys should be able to answer.

Recently put another auto box in my car as my old one started mis-shifting and generally being a bit crappy and just wanted to make sure the trans fluid in it is the right stuff to be using cause i'd like this one to last for a bit...

I've got the A342E box with a stage 1.5MV shiftkit fitted and a transcooler, around 245 rwkw.

I'm currently using Dex III although have read i should perhaps be using Type IV?

Some people have said Dex III is correct for a shiftkitted box, Type IV for stock?

There isn't anything written on the dipstick that indicates either also...

Thanks in advance!

Go to Toyota and buy the Toyota stuff, it's fairly well priced and comes in little 4 litre metal tins.

I think it's a good general rule to use genuine ATF for your auto trans.

At least in the ones you care about . The cheapest dex3 is fine for daily hacks etc.

mike said dex 3 is fine, but type 4 is better
