man this pissed me off so much, i found the first bolt, the fill one. but i have no idea where the drain one is, i mean i just couldnt find it... does anyone have anymore pictures that show 'where' it is like he showed 'where' the first one is by circling it or something? cause i spent 30 bucks on that syncromesh and i wanna use ittttttt
lol thanks alot if anyone can help

>I'd like to do my tranny fluid soon, as far as fluid, I hear some use ATF with good result, and I hear some use Synchromesh with good results. If I went with ATF, I'd use Royal Purple Max ATF.

Anyone use this stuff before with good results? And does anyone know what fluid the manual actually calls for?

>you can mix atf in with gear oil, that's what Toyota does with most of the newer cars...

>I think I'm just going to buy the Royal Purple 75W-90(?) tranny fluid and see how it goes.

>Ive done mine with Synchromesh and it shifted like a dream afterwords. Just some advice though, those bolts WILL give you a hard time but with some PB blaster and some good 'ol muscle they will come right out. Also if your previous owner was like mine then that fluid is still the original that came in the car. When I drained the old fluid out it was a burnt copper color and smelt something awful. It might have been overkill but I changed the fluid drove it for about 2 months or so and then changed it again and the fluid looked a lot better. And a pick for my tools of the trade

>Gearbox Oil Selection

There are many many different grades of gearbox and differential oil. Toyota recommends GL-5 for the gearbox in all GT-Four models. Many disagree, but it is vital that a GL-5 is used, with good reason! Some use auto trans fluid with good results, it is now specified for most fwd Toyotas.

I have tried a few different gearbox oils in my eight years of ownership. The oil my ST165 came with was unknown so I changed to Pennzoil 75W-90 semi-synthetic. Despite this oil working very well in the W55 gearbox in my Celica Supra, it was not very good in the GT-Four, resulting in a notchy gearchange.

When my RC gearbox was fitted they used a Castrol oil. I assume this was Castrol Syntrac, as they suckered me NZ$35 a litre!! Despite the gearbox having just been rebuilt, the gearchange was crap! Very notchy.

I (again) changed to Redline oil, which at NZ$20 a litre was pretty reasonable. The correct oil to use in a GT-Four is 75W-90NS. This is the right viscosity rating, is a GL-5 oil and does not have friction modifiers for a LSD. The GT-Four gearbox does NOT have a limited slip diff in it! The viscous centre diff is a sealed unit and therefore unaffected by oil selection. This made a noticeable improvement to gearchange and was well worth doing.

GL-5 oil is mandatory in a GT-Four gearbox. As the excess traction of 4wd does not allow wheelspin the extra load is taken by the ring and pinion (the highest stressed parts in the gearbox). As a result of the high loads the contact surfaces of the teeth are known to wear prematurely. This was evident in my RC gearbox, which despite having new synchros had noticeable wear. We can only presume that the gearbox wore due to high mileage causing a poor gearchange. The owner used GL-4 oil to improve the gearchange, which increased ring and pinion wear. It was then rebuilt soon before I bought it. Hence use GL-5 or you will regret it.

That said, my RC gearbox was eventually replaced with a normal ST185 gearbox when the clutch failed. The gearchange in my RC box had deteriorated and I could trade the box over for only a $100 or so so I did so. I ran the new gearbox on ATF and the gearchange was excellent, who knows about the longativity though!
