I have recently bought a 1968 Ford 4000 Select-o-speed. The transmission oil recommended in the workshop manual is 'M2C41-A transmission and hydraulic oil'
Does anybody know the equivalent standard grade of oil.
I've had a quick search and the closest I've found is ISO 46, SAE 30 - equivalent to Ford M2C41-B, is this the same?

David,

The oil in a SOS gearbox is a hydraulic oil rather than a straight oil. Check with your supplier who should be able to match it. Ford number was ESNM2C41A0.

New Holland Dealer has suggested Ambra Hydrodex Transmission oil.

There's a few numbers. I presume it is the specifications the oil meets.

SAE 10W
NH 530A
Dexron IID Lev.
M2C 163-A

And the text reads;
'ATF transmission oil for hydraulic power steering, hydrodynamic transmissions, torque convertors & hydraulic brake control of tractors, agricultural machinery, loaders and excavators.'

That sounds more like it! I would use that.

We have changed the oil as above now but are now having a few more problems. Any help would be appreciated.
The story so far… We bought this tractor knowing the transmission was not working but with the attitude that; a) it’s a machine and it will sort, and b) its done 8500 hours so it must have worked for that long.
Firstly we gave it an oil and filter change as above. Next we set up the adjuster screws as per the workshop manual but there was still no movement. You can hear the tractor working as you change some gears but there is no movement at the wheels.
We then had a little fiddle with the adjuster screws and managed to get the wheels moving forward when the gear was reverse. By tightening them up we can get the tractor to stall, why is this? A further fiddle and we got the two reverse gears working and 9th and 10th. Park and neutral also work as they should. The problem is that 1st-8th don’t work at all. I have studied a diagnostic table but there is no explanation for this combination of results. Any ideas?
Thanks in advance, David.

David,
Band setting and the sequence in which it is done is of extreme importance, so are the pressure settings of each clutch. You really need the gauges and the workshop manual with you to set things up there is no way to fudge it by trial and error.

The reason you are getting the engine to stall is because you are getting the equivilant of two gears at once in a normal transmission.

There could be a number of reasons why things are not going right as this is a complicated transmission.

Thanks Brian,
I'll get hold of some gauges and try setting up again. No doubt I'll have more questions after that.
