Sup guys want to change gearbox oil , the castrol bot 130m is discontinued , now they hav bot 402m but thats 75w 85 NOT 75w 90 , which other gearbox oil do you guys recommend? heard of shell spirax 75w 90 did any1 try it?

Do you know what viscosity the oil is? An you used 2.1litres of Automatic Transmission Fluid (ATF) in your 6 speed box?

Bru, the toyota gearbox oil is 75W90 gl4, is there any difference from this to the castrol syntrans EP75W90 which i know is fully synthetic?

Re: Gearbox Oil For RXi 5 speed

will check the viscosity again, btw its the exact same oil thats being used on the corolla proffessional 6speed gearbox...it only comes in 4ltrs, still happy with it a year later

The EP in syntrans also stands for extreme pressure additive, helps the oil when being squeezed between gear teeth.
so thats one advantage

The GL rating of the oil doesnt have anything to do about it being sythetic or non synthetic.

GL1 is the lowest rating oil with GL6 being the highest, however 6 not even being available to the public.

The Syntrans is GL5 so it has a higher rating than the toyota oil which is GL4.

taken from wikipedia

API GL-1. Oils for light conditions. They consist of base oils without additives. Sometimes they contain small amounts of antioxidizing additives, corrosion inhibitors, depressants and antifoam additives. API GL-1 oils contain no EP addives, are designed for spiral-bevel, worm gears and manual transmissions with synchronizers, in trucks and farming machines.
API GL-2. Oils for moderate conditions. They contain anti-wear additives and are designed for worm gears. Recommended for proper lubrication of tractor and farming machine transmissions.
API GL-3. Oils for moderate conditions. Contain up to 2.7% anti-wear additives. Designed for lubricating bevel and other gears of truck transmissions. Not recommended for hypoid gears.

API GL-4. Oils for various conditions - light to heavy. They contain up to 4.0% effective anti-scuffing additives. Designed for bevel and hypoid gears which have small displacement of axes, the gearboxes of trucks, and axle units. These oils are standard for synchronized gearboxes, especially in Europe, and may also be recommended for non-synchronized gearboxes of US trucks, tractors and buses and for main and other gears of all vehicles. GL-4 oils may also be used in many limited-slip differentials.

API GL-5. Oils for severe conditions. They contain up to 6.5% effective anti-scuffing additives. The general application of oils in this class are for hypoid gears having significant displacement of axes, generally non limited-slip differentials. They are recommended as universal oils to all other units of mechanical transmission (except synchronized gearboxes specifying GL-4). Some GL-5 oils in this class, which have special approval of vehicle manufacturers, can be used in synchronized manual gearboxes. API GL-5 oils can be used in limited slip differentials only if they correspond to the requirements of specification MIL-L-2105D or ZF TE-ML-05. In this case the designation of class will be another, for example API GL-5+ or API GL-5 LS.

API GL-6 is not applied any more as it is considered that class API GL-5 well enough meets the most severe requirements. When API GL-6 was still in use, it denoted oils for very heavy conditions (high speeds of sliding and significant shock loadings). They contained up to 10% high performance anti-scuffing additives. They were designed for hypoid gears with significant displacement of axes. However, in 2011 at least one company offers new polyol ester based API GL-6 oil, mostly for racing applications. The application is limited to certain types of manual transmissions, but improvements in BSFC of about 5% in standard weather and driving conditions and up to 15-20% in cold extremes (arctic weather conditions) can be expected.
