Hi, I am looking for an appropriate grade of oil for 440 transaxle (std M60 gearbox). I filled with Mobilube HD 80W/90, which is now giving stiff cold shifts as winter approaches. No oil company database has a specific recommendation (they all seem to use the same information).

Try Amsoil 75W-90. I put it in my 96 Toy 4Runner. It is in the differentials (front/rear), transfer case, and manual transmission. It made shifting SOOOO much easier; especially in the winter.

Best of Luck

What I can find is that it's Volvo P/N 3345534-6 and has to comply with API-GL5 quality. Haynes states either Gear-Oil SAE 80W or a 75W/90S.

Bye, Arno,

Thanks all for help. Good to know it needs to meet GL-5. In that case I will use either Mobil (Synthetic) SHC-M 75/90, or Castrol (Mineral)EPX 75/80 (both GL-5). Will let you know how it goes.

Assuming that the box calls for gear lube (and I really don't know)-

try Mobil 1 synthetic 75W-90. Should make a noticeable improvement over the non-synthetic.
