What oil goes in a 5lm60 transmission?
synchromesh transmission fluid, VERY critical to use in a 5lm60 to prevent failure.
Pour the transmission fluid down the hole the transmission dip stick goes in. You will need a funnel to do it right. WRONG! Do not pour transmission oil into your engine oil compartment! There is no dipstick for transmission oil, at least not on the manual transmission. To fill the transmission, you must pump or pour fluid into the fill hole on the side of the transmission until it dribbles back out.
On all Eaton-Fuller transmissions, the fill plug is on the left side of the transmission. You insert the drive end of a 1/2" socket into it, and turn it counterclockwise to unthread it. That's where the transmission oil goes. Eaton-Fuller recommends you use either 50W synthetic, or 80W if you're going with mineral oil.
The place to fill it is a threaded hole in the side of the transmission that has a plug screwed into it. There are actually two....the lower one to drain the oil and the upper one for refilling purposes. Look near where the axle goes into the transmission. You refill until oil begins to run out. It's not easy to get it in there, though, because the hole goes in from the side. You will…
