Awhile ago, Centranz’s Shop Supervisor Mike Cullen asked a customer how much transmission oil he added to a transmission for a piece of heavy equipment.
“He told me he put in seven quarts of transmission oil,” Mike says. It should have been seven gallons! “A lot of people operate transmissions without the proper amount of oil,” Mike says. On average, a newly rebuilt transmission for heavy equipment requires about 16 gallons of transmission oil. “It’s probably the most common problem we see here.”
Signs of a transmission that’s running low on oil include overheating and cavitating, or sucking air, which produces a chirping sound. “Always check your manufacturer specs for the recommended amount of oil,” Mike says. “Trust me, you don’t want to see what happens when you run low.”
