After careful study of the owners manual I had download from VolvoPenta before starting - yes I know a rarity to RTFM before starting - I proceeded to attempt to change the oil
in my transmission
On drawing the oil
out of the dipstick I noticed it was red rather than the golden brown the manual stated. Instantly alarm
bells started sounding. Did I have the correct oil for the job? I had 4 litres of SAE 15w-40 as per the technical data tables in the manual but that's the same as the stuff that goes in the engine
. This stuff coming out the gearbox
looks like automatic transmission
fluid but I have never seen this stuff graded like engine
oil, it is more normally graded DOT 4 or DOT 5 the same as brake fluid (in fact they are often the same stuff).
So not wanting to screw up I stopped extracting and carefully poured the contents of the bucket back into the gearbox
before doing some research
. So I am putting out a call for all the gearheads out there.
If the manual says the S-Drive gearbox needs SAE 15w-40 is this the same as good old fashioned engine oil or should it be transmission fluid of the same grade?
My gut says looking at the stuff in there already that it should be transmission fluid.
Cheers (and cold beers) for the help
