Gear oils - help!

According to the owner's manual from the donor car, the transmision I'm using needs 75W90 API GL3 or GL4 lubricant. I've searched a few manafacturer's websites and cant find one to match, it seems 75W90 only comes in API GL5. What does the API GL# bit mean? Can I use GL5 where GL4 is specified? Valvoline makes a 75W85 API GL4, should I use this as an 'inbetween'?
I'm using ATF III at the moment, but it makes the transmission noisy. I searched but couldn't find any definitive info - help me, I'm desperate!
Cheers,
Andy
