Thread: Gearbox issues and oil

unlikly to fix problem.

the oil specified by rover was upgraded to Caltex MTF 94 or similar.
this oil gives better changes unless syncros worn, and is much better for the boxes life.

Michael.

If it's been run on ATF most of it's life the syncros are probably tired. Penrite 75 will normally be OK, I run Valvoline dura gear 75/85 in most of them and they are fine a part from the first few minutes on a cold day. You could try some Castrol Syntrans MTF, if you don't mind paying $20 a litre this seems to work pretty well. Chances are it needs a freshen up however.

Tried to get oil for my Freelander gearbox - none of the ususal places such as Autobarn, Repco, Rare Spares, SuperCheap carried anything - had to go to the local Castrol Depot to buy 2 litres of Castrol Syntrans 75 ($20 a litre - but real easy to get into tight filler holes as it flows like water). On my travels no one had MTF 94 - particularly Caltex.

Any ideas on where to get Caltex MTF 94 in domestic quantities rather than commercial quantities - I am about to do an oil change on the disco. It has always had ATF in it and there have been no problems to date but I want to change before I do develop problems.

I am also in Canberra.

Cheers

Any equivalent to MTF 94 wil be fine.

Michael.

I rebuilt my LT77 afew weeks ago and found that the Penrite 75 felt too thick. I've replaced it with Penrite Synthetic ATF (about $30 for 4 litres). I spoke to the people at Penrite and they said the Synthetic ATF would be a more durable oil than the 75, especially if the box was getting hot.

I'd say go with the synthetic ATF.

the easiest place to buy Caltex MTF94 is from a Land Rover dealer, as the minimum buy quantity from a Caltex depot is 20 litres.

As to an ATF being more durable than an MTF in a manual gearbox, I'd say that says more about their MTF than anything else :wink: If you really want to use an ATF, I'd use Castrol Syntrans or one of Redlines ATF's like their D4.
At least Redlines ATF's meet the API GL4 gear oil spec.

Syntrans is an MTF as far as I'm aware, TransMax is synth ATF. Penrite 75 is a mineral MTF, not sure if they make a synth one in their 10/10ths range.

I find that in Brisbane at least Valvoline dura gear works well in most of them for general use and you can get it at Super cheap if you want, I think thats what MR put in on the cars they service/rebuild.

Went to to the dealer and they wouldn't sell me any oil. Thats when I went to the Castol depot and was able to buy Castol Syntrans 75 in litre bottles.

Don't know about the disco but the freelander uses the Valvoline Dura equivalent in the in the IRD but not the gearbox - they definitely use different grade oils so the Valvoline Dura cannot go in the gearbox - in fact Valvoline do not list an oil for Freelander Gearboxes Refer to Dealer is the note. Like wise Castol list a different oil for the IRD.

I think Castrol list Syntrans 75 for a Disco gearbox but I am not sure.
