Hot Gearbox

[Bleach1]

I replaced the Transmission oil in a manual last week on an r32. I used VMX80. The gear stick used to get warm with the old oil which looked as if it hadnt been changed in its 100,000km life. Now with the VMX80 it seems to get much warmer without even giving it a real thrashing.

Any ideas?

what temp ? or are you just estimating?

in the manual i have for the euro 200 sx they have temp sensors on the diff. the red light comes on at 180 deg c then turns off at 155 deg c.

which is ***en hot.

VMX80 is resonably thick, especially for a performance G/box.

Most import manuals will tell that the G/box oil never needs changing... Bullshit.

But it doesn't need to be changed very often. I would recommend u go and spend some money on decent synthetic B/box oil.

Just by feel up through the gear stick,

lol VMX is not reasonbly thick. Its damn thin. 75W-80 is about the thinnest gear oil you'll find!

Maybe the VMX 80 isnt too good in ur box and u need something with better protection. Try Castrol Syntrans (synthetic).

vmx80 isnt tooo bad either.

ive found that both redline and vmx80 get pretty warm when uve given it a few fangs, otherwise its not too bad

Redline is like glue it's that thick. It needs a lot of heat to get up to operating temp.

I can feel it in the side console.
