Switching to a higher quality fluid was necessary to prevent transmission breakdowns caused by the commercial grade lubricant burning during stop-and-go city driving by multiple drivers.
Monolec® Power Fluid (7500) is a nonfoaming lubricant recommended for combination gear-hydraulic systems, hydraulic transmissions, wet brakes, and torque converters, effectively rejecting water.
Monolec 7500 effectively protects truck transmissions, allowing for drain intervals of 45,000 to 50,000 miles and enabling 1.9 million miles of operation without major repairs or transmission failures.
Transportation Management, Inc. provides door-to-door transportation 24 hours a day, 6 days a week for handicapped and disabled passengers in metro Grand Rapids, Michigan.
The passenger fleet consists of 1998-2002 Ford E350’s and E450’s with Ford E40D transmissions.
Due to stop and go city driving, by many different drivers, they were looking to use a higher quality fluid to extend the life of the transmissions. The commercial grade lubricant they were using was getting burned and causing transmission breakdowns.
The local LE lubrication consultant recommended Monolec® Power Fluid (7500), which is for combination gear-hydraulic systems, hydraulic transmissions, wet brakes, and torque converters. It is nonfoaming in service and rejects water.
Drain intervals have been established between 45,000 and 50,000 miles and oil samples show Monolec 7500 still protecting the transmissions. The trucks have run 1.9 million miles without any major repairs or loss of transmissions. The average truck has approximately 100,000 miles.
