MJH2454 Posted July 21, 2020 Report Share Posted July 21, 2020 I'm going to change the oil in my gearbox and overdrive, I have no idea if it has ever been changed and at 50,000 miles seems like a good idea. The question is should I also change the filters in the overdrive unit? How difficult is it to change them and can I do it with the gearbox/overdrive in place? The overdrive is working flawlessly at the moment, so should I leave well enough alone with the overdrive? Thanks Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 21, 2020 Report Share Posted July 21, 2020 if a D type i would remove the filter cover ( passenger side) the filter sits inside just pulls out, it will be a gungy, so will the 3 magnetic rings that are removable give it all a clean in white spirit or brake cleaner , even petrol whatever you tend use , dont overtighen the cover its a simple cork gasket .that will crush .

Waynebaby Posted July 21, 2020 Report Share Posted July 21, 2020 From my own messy experience, I'd recommend that you take the filter cover off AFTER draining the gearbox oil! Wayne 1 Link to comment Share on other sites More sharing options...

avivalasvegas Posted December 10, 2020 Report Share Posted December 10, 2020 Sorry to hijack this thread but would this oil be the correct grade? I plan to renew the fluid in the differential and transmission and would like to know how many litres I should order. https://products.liqui-moly.us/oils/gear-oil-gl4-sae-85w-90-1.html Link to comment Share on other sites More sharing options...

Would I buy that? no, as I don't like the sound of the moly bit. An EP 80, 90, or 80-90 (which is what I have been using for almost 30 years now) but needs to be GL4 in the gearbox, GL4 or confirmed yellow-metal safe GL5 in the diff. As to capacity, diff is a pint I think, gearbox about 1 1/2 pints for non-od, just over 2 pints for OD. Best to buy 5L, plus an oil syringe to get the oil out the diff, and refill it. You won't get much better than this (unless racing/trackdays) https://www.ebay.co.uk/itm/Millers-Oils-EP-80w-90-GL4-Gear-Oil-80W90-GL-4-Transmission-Fluid-5-Litres-5L/274386977181?epid=6013647521&_trkparms=ispr%3D1&hash=item3fe2bd019d:g:pFwAAOxyJX1TF0vP&amdata=enc%3AAQAFAAACcBaobrjLl8XobRIiIML1V4Imu%2Fn%2BzU5L90Z278x5ickkY3FSd4Ad8xn3oRtkVexxrIFg514ZGommKIh5qYwKE2naOaqSxTEYPfcsV9kkXqopHAXk88ADMA947YLUl7B8k5kBjuTT96%2FXeN1Ih1W99r4Xv7XJLC41PtambNpg8B7bnD%2F2zjDjcPBfzulojN2Ls3zQPDnpY1EPQXPoB8MDfnzzdOGkBty9SLDassPvRmo59SmSDbd73FrXmRmVMmlgu1GntoVc%2FvCEMObgjrOT5hJpWx87UXaVas0A0OouLTAM0tgzT%2BnKPZOR7nfVCeR%2FdxJep7zfQsUV5%2FKRWrBNF7t5OY61JFBICNJK%2F1%2F92NntUn%2BUT50F7OAexlJuAzSGtP7m0X%2FDN9OdilnMu6qi16YhCZqf%2B6dRd%2FJ4bXERojx1E1no9O8MweQFFSeOS0Shv%2F%2FyAXYZKeCtz0wNRSS2LRWR6Tk5Wyn6j0r%2FE%2F2Qt5pef2BfElHHMt0yAFJ1IVzsQepMwoL8FBwMnYH%2B%2BkZxLNJW9771wZAY0fccZKP2u5j%2BSmTxPaq3g7sZTQ1NeAvUc9qPzpWrCUdSyVfP7PforCEnwb48a%2FwqCda2T2XxjQAJHDKs2eGMuQAi6w2vODpo%2BqQQ5TkANFkNzqkTfPtxWPnVr6s1EKeQSvr2DiOgyIGmA1HzwmrdPN%2FuIhJy0Yg51lZiAPQfZ5tur6RnbdzjYDilQdUfwR%2BbjwczbWSwB1qJeTkQpQVJmcUAMCHeS7DIIF56uYogHrvqzdxb%2BrlYGZqQwkwrb5V57HX9nEq0exXiy7ZWxk2EpKPG12lWLsPeGA%3D%3D|cksum%3A274386977181bcb6e77945224f1fbe34e831fef823d1|ampid%3APL_CLK|clp%3A2334524 1 Link to comment Share on other sites More sharing options...
avivalasvegas Posted December 11, 2020 Report Share Posted December 11, 2020 Thanks! I use Valvoline VR1 20W50 in the engine as it has an excellent reputation and high Zinc content. Liqui moly also has an excellent reputation in the German car scene, including my vehicles, but I prefer purchasing the community recommend oil. Sounds like you’re saying that Miller’s is it and nothing else comes close? Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 11, 2020 Report Share Posted December 11, 2020 any addative oils is bad news for the syncro and especially the overdrive dont want any slippery addatives laycock specify engine oils for the overdrive but Triumph have a concession to use ep90 as the gearbox is going to fight for life if using engine oils many other marques do use engine oils in the gearbox but not triumph if youre worried about diff life fill with a EP140 GL4 many use that in the diff with better noise suppression Pete Link to comment Share on other sites More sharing options...

Wayne Yep, got that (oil soaked) t-shirt too. Always turn your head away when removing sump plugs or other 'oil retaining' items too - I've yet to taste a motor oil that's splashed on to my face and into my mouth that I liked the taste of.🤢 Link to comment Share on other sites More sharing options...

It takes an amazing amount of old towels or kitchen roll to mop up even a pint. Been there! Re the diff oil - Paddocks are selling a diff oil, Dynolite, that's 85 - 140 which they reckon is a good replacement. Used in Maseratis and Jaguars according to Moss.

If you are happy with VR1, you will be happy with my recommendation. 1 Link to comment Share on other sites More sharing options...

It's likewise amazing how much water remains in the engine block...when you've drained the radiator but forgotten to remove the block drain plug before removing the head...😞 Link to comment Share on other sites More sharing options...
