can't seem to find the correct spec oil for the trans axle. Manual shows "Case FDL multipurpose gear lubricant, Api-gl-4, Mil-l-2105b, sae 80 or sae 90. Any in site or replacement type oils would be helpful. Thanks in advance.
You already have your answer jamer...... here in AU, I use 85W/140 as it does not get very cold were I live.
The sae 90 part it ok but the gl4 is what I can't seem to find. Is it ok to use gl5?
Apparently the GL5 does not agree with yellow metal (brass synchro rings) in transmission/ transaxle assemblies. So try to find GL4.
