dave88sw Posted July 11, 2014 Share Posted July 11, 2014 Hi, Is there a special method to filling an R380 with a gearbox oil cooler? I.e. do you have to run it in gear (transfer neutral) to fill the oil cooler and then continue filling or just drop the oil and refill to level as you would without a cooler? Cheers Dave Quote Link to comment Share on other sites More sharing options...
mmgemini Posted July 11, 2014 Share Posted July 11, 2014 I just drain and fill as I would a 380 without the cooler. Seems to work for me. First fill though run the gearbox then check oil level. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted July 11, 2014 Share Posted July 11, 2014 IIRC its thermostatically controlled so wouldnt you need to do a longish hot run and then check it afterwards ? Quote Link to comment Share on other sites More sharing options...
dave88sw Posted July 11, 2014 Author Share Posted July 11, 2014 Ok, good advice here , the reason i'm asking is i want to change the current old ATF for MTF94. So if it has a thermostat, would it allow the oil to drain from the oil cooler with the box oil or is it worth dropping a pipe off and allowing to drain?

Where would that thermostat be I wonder ? I have a Wolf system on my Defender, I'm not aware of a thermostat fitted. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted July 12, 2014 Share Posted July 12, 2014 18 - Housing-transmission thermostat FTC2687 [ Manual ] On a P38 trans this is how its listed On a V8 defender listed Housing-transmission thermostat V8 except oil cooler (air cooled) FTC2104 [ Manual - V8 - except oil cooler (air cooled) ] oil cooler (air cooled) FTC2687 [ Manual - V8 - oil cooler (air cooled) ]on 6cyl defender 6 Cylinder FTC2687 [ R 380 - Manual - 5 Speed - 2800 cc - BMW M52 - 6 Cylinder - Petrol ] it might be that the2104 is non stat type , Ashcroft specifically mentions that his kit is a non thermo type HTSH Further thought it might be that if its just pipe type "cooler" no thermo , but if proper matrix type oil cooler it has a thermo ?

mmgemini Posted July 12, 2014 Share Posted July 12, 2014 Yep. my gearbox take off came from Ashcroft many years ago for a Defender Quote Link to comment Share on other sites More sharing options...
tacr2man Posted July 12, 2014 Share Posted July 12, 2014 Yep. my gearbox take off came from Ashcroft many years ago for a Defender Do you by chance have a temp guage on your cooler ? , also which is the outlet on the adapter upper or lower?

mmgemini Posted July 12, 2014 Share Posted July 12, 2014 Do you by chance have a temp guage on your cooler ? , also which is the outlet on the adapter upper or lower? LOL. LOL. You know I have Weetabix for breakfast each morning / I can't remember what I had today No I don't have a gearbox temperature gauge. For the outlet I just followed, I think, the Wolf parts picture. I fitted mine in 1995 I think. Quote Link to comment Share on other sites More sharing options...
ajh Posted July 12, 2014 Share Posted July 12, 2014 A temperature gauge is nice and all; but what I really want is a low-oil sensor.... any way to fit one of those? and don't ask me why I'm still in a bit of a bad mood about it. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted July 19, 2014 Share Posted July 19, 2014 Your going to have a problem with that intention , due extreme temps , how to mount and type of sensor , within confines of gearbox try googling oil level sensors to see whats avai;able Quote Link to comment Share on other sites More sharing options...
Boydie Posted July 19, 2014 Share Posted July 19, 2014 The oil cooler thermostat is a wax pellet type that will "fail" to open. It is located in the twin pipe connection on the left hand side of the gearbox - the wax pellet thermostat is located behing the seal plate which is removed by removing the circlip. Easy way to fill the system is to get the gearbox up to temperature - feel the oil cooler supply pipe - and then top it up. Normally the oil cooler wont drain fully so if you have only done a gearbox oil change I wouldnt worry too much about it, you arent talking about a huge amout of oil here, only about 1/2 litre Quote Link to comment Share on other sites More sharing options...

I have fitted a fan cooled 13 row cooler , as gearbox is dealing with a bit more torque than designed for ! Quote Link to comment Share on other sites More sharing options...
Tanuki Posted July 20, 2014 Share Posted July 20, 2014 Just drain the gearbox and refill to the 'dribbling-out-through-the-filler-hole' point, drive for 6000 miles and re-check the level. Too many people are much-too-paranoid about this sort of stuff. In the business-world we trust the maker's service-book guidance even though we measure downtime by the dollar.

tacr2man Posted July 20, 2014 Share Posted July 20, 2014 In my instance , makers service book not much use , as its non standard , and probably being taken beyond its standard envelope , so a bit of paranoia not going amiss Quote Link to comment Share on other sites More sharing options...
Boydie Posted August 9, 2014 Share Posted August 9, 2014 Would'nt the oil capacity for the V8 give you a quantity, the gearbox is the same as fitted to the 300TDi only the V8 has the oil cooler fitted as standard, so I assume the oil capacity for the R380 + oil cooler as standard fitted to the V8 would be slightly more that the non oil-cooled 300TDi.

Boydie Posted August 9, 2014 Share Posted August 9, 2014 Wow, as I understand it the R380 gearbox is designed to handle 380NM of torque so you must be really putting it through the hurdles as it were. I only retained the oil cooler when I installed the R380 and discarded the ZF4HP22 and retained it only due to the higher ambient temperatures experienced here in Oz - up to 50 degrees C in the deserts - and I just used the standard ZF4HP22 oil cooler and retained the auto temperature sensor in the oil line. There isnt any data available (or that I can find) on the designed switch operating temp but mine switched at just under 98 degrees C - arround 200 F - easily tested in a pan of water with a thermometer and mulimeter while your financial advisor is out spending your hard earned. Again, I assume that as the R380 can be run on ATF - the same as the ZF4HP22 - the oil temperature high limit will be the same. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted August 10, 2014 Share Posted August 10, 2014 Its behind a BMW M57 TDI which has also been remapped , and whilst not having done any rolling road analysis , you can tell by the way it accelerates my 110 (heavy ) it has a lot of torque . I am running Redline oil , which I started using when living in WA , and would recommend that it would be a good move for you , even though you live on the cooler side ! Will have a look for a specific V8 capacity . Quote Link to comment Share on other sites More sharing options...
Boydie Posted August 12, 2014 Share Posted August 12, 2014 Agreed, and while I run my R380 on the LR recommended full synthetic as this oil is a Land Rover upgrade / alternative from AFT again, it should have the same high temperature high limit as ATF, and while the east coast is cooler (its snowing this morning in Katoomba !!!!!) Julie and I spend as much time as we can exploring the Great Victoria Desert, the Anne Beadel, the Connie Sue and the Canning Stock Route. Great tracks and splendid country.

Adam001 Posted August 12, 2014 Share Posted August 12, 2014 I looked for 2.8-3L when I filled mine up. I have a Mocal 10Row cooler mounted vertically with a P38 oil cooler block (it has a thermostat). I filled the gearbox up to the level, nipped it up then pulled a pipe off the top of the cooler and filled it up. Quote Link to comment Share on other sites More sharing options...
