botzitaliano 36 #1 Posted February 16, 2015 Im looking to do a servicing on my d250. When i read in the manual its a little confusing. Is the transmission and transaxle the same thing?? I want to change the fluid. And in the manual it just shows the 2 drain plugs on the axle. And the fill on the top of the axle. from what i understand they both take sae 90 gear oil and 5.5 guarts so to me it sounds like the same thing, but i want to be 100 sure before i start. Im a little confused as you can tell. If anyone can help me clarify id greatly appreciate it thanks. Share this post Link to post Share on other sites
blu_stang 14 #2 Posted February 27, 2015 (edited) The transmission and transaxle are for the most part interchangeable in this instance. The top drain plug on that transmission is at the bottom of the hi-lo range gear box. The second plug is at the bottom of the main transaxle case. Both gear boxes are filled from the same cap at the top, behind the right rear wheel. Regarding the oil, be sure to use GL-4 SAE 90 Hypoid gear oil. It's expensive, and you'll need two of those jugs it comes in, to fill it. But it's the correct stuff to protect those big brass gears inside. I've found that Amazon has the best price on it.

shallowwatersailor 3,213 #3 Posted February 27, 2015 (edited) NAPA carries GL-4 85W-90 oil. I use that in my equipment with bronze gears/bushings including the Gravely attachments and MW Power Trac transmission. I wouldn't trust anything that says it is GL-4/GL-5 compatible. Just use GL-4 rated oil. And yes, $$$. Edited February 27, 2015 by shallowwatersailor Share this post Link to post Share on other sites
backinthesaddle 0 #4 Posted March 29, 2015 Is the GL-4 SAE 90 Hypoid gear oil a replacement for type "A" transmission oil? I need to change the fluid on my '69 Charger 10, and don't want to mess things up. Share this post Link to post Share on other sites
pfrederi 17,116 #5 Posted March 29, 2015 Is the GL-4 SAE 90 Hypoid gear oil a replacement for type "A" transmission oil? I need to change the fluid on my '69 Charger 10, and don't want to mess things up. Absolutely NOT!!!! It is 90weight gear oil ...type A now Dexron ATF is about 20w. What color is the fluid in Your Charger now??? Cherry red is ATF tan means it has been changed out to Motor oil which is Ok but it should be 10w-30 or 10w-40. Do not mix ATF and Motor oil. Changing requires a complete flushing and at the price of oil /ATF these days isn't worth it in my book. My electro 12 and Charger both run just fine on ATF.

squonk 38,843 #6 Posted March 29, 2015 It's the sulfur in the Gl-5 that causes the problem with brass. Synthetics have less sulphur and that's what I use. https://www.amsoil.com/lit/ConventionalVersusSynthetic.pdf Share this post Link to post Share on other sites
