Gearbox and diff oil

Post by germ » 29 Jun 2007 11:18 pm

well erm today i finally got round to changing my gearbox and diff oil...............

OMG!!! WoW :!: :!: :arrow: its soooo amazing the differnce the gears go in super smooth and fast,its quiter, the car feels much faster.

i put fully synthetic racing oil in the gearbox (automatic,and manual) gearbox oil, the red stuff. and 80w somthing semi synthetic diff oil in the diff.

no really no jokes the differnce is amazing, the oil was believed to never of been changed just topped up. - i think this was the best 52 euros i ever spent.


Just thought i would share that with you :lol:

Cheers

52 euros? that's well expensive :P

I reckon I could do it for... £15 which is about 23 euros.

I thought that diff needed ATF or bad things would happen?

The gearbox needs ATF, the diff claims to need 90 although i found only 80w90 is easily obtainably. i ended up getting a gallon on ATF and a couple of litres of 80w90 "heavy gear oil" when Mac and I changed my 340 to a 5 speed. must of cost around £25 for the oil.

Yup, ATF in manual gearboxes and manual gearbox oil in CVTs ;) Make sure its the friction modified stuff though, so none of that ATF-F, you want a Dexron type, or if you can still get it, ATF A/A :)

hi,

from the posts here seems the gearbox oil spec causes some problems with local motor factors.

both castrol and commas own tech specs advise that 10W40 is used in the gearbox... cant be right.

the green books for the early (1980s) cars advises ATF type F or G. The later owners manual advises the same ATF type F but has a note of increased capacity for the 5 speed.

Ive found comma ATF TQF locally which another post here says isnt applicable.

Anyone know of a brand of ATF Type F? doesnt seem comma makes it.

ATF A/A is friction modified whilst ATF type F isnt.

cant seem to find Type F locally at the moment...

anyone know of a brand?

Type F is more rare, because it's an oil which some old Ford boxes use so not too common. ;) Shell Donax line has type-f oil. It's called Shell Donax TF.

Also Mobil 210 is type-f oil.

Just made up a new gasket for the diff and refilled it with 85w140 diff oil. :lol:

Much smoother and the oil doesn't splatter all over the car now when out on the highway. 8)

The ATF spec you're quoting is for different gearboxes, the M45R and M47R units fitted to 300s are different and all use ATF type A/A, the closest modern equivalent is Dexron, a friction modified oil.

ATF F is a non-friction modified oil.If you put in ATF/F then I don't know what would happen but I guess it wouldn't be too good.

The advice from Castrol is passed down from Volvo. They now advise that 10w-40 engine oil is used rather than any sort of ATF, that goes for the M45/46/47 found in 2/7/9 as well.

I've got old Volvo books which quote Type F oils for all M45,M46 and M47.. Mobil 210, which is old type-f oil. (Though 740 manuals quote Type-F or Type-G)

hi Andy /Pettaw and Fuse..

Ive checked a number of green volvo books, owners manuals and autodata. so far, everyone says ATF type F.

The only ATF tpye A/A listed is by haynes and the haynes 340 book is full of errors.

10w40 doesnt make sense... going to do more research on this before.

where did you hear of using ATF type A/A apart from Haynes?

both the 1980 green books and an 1989 owners manual version all say ATF type F.

I think Ive found a comma product which is type F. matches what you are saying Fuse in that it is listed as a ford oil...

Yeah my green books also say type-f so I trust those. Also every "volvo-guru" who I've talked to have used type-f. Owners manual and even my Alfamer (translated from Haynes) manual says type-f Mobil 210 so I think that the original Haynes one has an error, because all original Volvo books and manuals say type-f. ;)

One "volvo-guru" told me that friction modified ATF is too "slippery" for synchros in Volvo boxes, that's why type-f is recommened. Of course it works with friction modified too, but I would guess it isn't so good for synchros..

I got my data from the official Volvo green books (copy of which is in the technical section on this site) for the 300 series gearboxes, also the specification sheets. AFAIK they were the lastest version's that Volvo produced. The owners manual I have from 1988 doesn't give a specification, it just says ATF. ,

Its also stamped on the side of the gearboxes. A/A


EDIT: how odd, the owner manual from 1989 gives the spec as F or G.
