Hi, new owner here. I'm changing vehicle fluids soon and was wondering if anyone has specs of the various fluids, differentials, manual transmission etc for a 2003 manual 4WD. Does the transfer case use a separate fluid and does the clutch hydraulics operate off the brake system or a separate system.

Thinking of using Redline products if anyone has experience with those in a Rav4. Thanks.

Thanks James, planning on printing a copy and confirming numbers with the local dealership service department, subsequent TSB's could have created change to any of that information.

Thanks Beaumont, the Amsoil site has fairly complete information. I will likely run group V POE ester based oils, Redline or Motul for component internal cleanup and seal conditioning and then switch to PetroCanada fluids.

I've been doing a lot of reading about trans fluids, to try and improve the poor 1st - 2nd gear shift on my 4.1. This is made more difficult by the 4.1 not having seperate gearbox and transfer, so using the same oil. The 4.2s are seperate I believe.

GL5 is for hypoid diffs and GL4 for gearboxes. GL5 shouldn't be used in gearboxes for 2 reasons -
1 it can contain things that damage synchros.
2 it is slipperyer than GL4 due to the way the crownwheel and pinion mesh/turn, so will reduce effectiveness of synchros, so worse gear change.

So I would only use a GL4 in a gearbox and Redline's MT90 is said to give the best change while still being the correct 75W90 GL4.

I don't know why Toyota spec GL5 for seperate gearboxes, but can understand the difficulty in getting the correct oil in a 4.1. So I can't decide between Redline's MT90 or 75W90NS for mine, maybe a mix of the 2?

Oh, as for engine oil, IMHO, the ?W30 grade required is more to do with mileage/emissions than temperature and engine protection.
Here in the UK the owners manual also includes 15W40 and 20W50 grades, depending on expected outside temps and it doesn't get anywhere near as hot or cold as parts of the US.
So depending on where you live and the mileage on your engine, I'd go for a ?W40 or ?W50. I'm probably gonna use a 10W40 in mine.

Thanks. Interesting that both the oils they recommend are GL4 and GL5 rated, so perfect for the 4.1's transaxle with shared oil.
I was however looking for one that specifically improves gear selection, and the MTL, MT90 and 75W90NS state they do this. Lots of searching has found several people confirming the MTL and MT90 do improve gear changes, some from MR2 owners.

The other interesting thing, looking at engine oil for the 4.2s, for the US they only recommend a ?W30, but for the EU they go up to a ?W50, which seems to back up my opinion.

Thanks Jim, adverts of both gear oils recommended by Motul speak to improved gear shifting. The 'Gear 300' product is the ester based version however with much lower pour point. Local dealership tells me that they use the Gear 300 75W90 in all components of various Toyota truck drivelines including Rav4 for winter temperature consideration.

Thanks again. I did a bit more reading on both Motul and Red Line. I found some worrying reports of Red Line MT90 causing bearing and gear wear, and breaking down with severe track use, so that's out now.

As you say, the Motul Gear 300 is less viscous at lower temps and is fully synthetic, so as far as I'm concerned, it is the perfect oil for the 4.1's combined gearbox/diff. I'll be buying 6 litres and using it in my rear diff too :)

I don't know why I didn't look at Motul first, as it's one of the few 'synthetics' that is actually 100% synthetic. I also use their 300V 15W50 in my turbo nutter car, due to first hand info about it's performance at very high on the engine dyno.

Now what shall we use for the engine?

Thanks Jim, winter temperatures frequently hang around -35C and occasionally drop to -40C in this end of Canada. I see Mobil 1 0W40 went on sale at the local parts store, 4.4 liters for about 15£ so that looks like a good motor oil choice for this season. This 03 Rav now has 100K miles so I will likely continue with a 40 grade of oil.
