    Versatile Fluid Ensures Smooth-Running Automatic Transmissions in Cars & Trucks

    Monolec® Syn Multi-Vehicle ATF (1150) is a versatile, high performance product suitable for regular- to severe-duty use in a variety of automatic transmissions in passenger cars and trucks. Replacing LE’s Trans-All EHP Automatic Transmission Fluid (1150), this new fully synthetic formulation has an uptreated additive package that includes Monolec, LE's proprietary wear-reducing additive. This improved formulation is fully compatible with the previous 1150 formulation. No conversion is necessary.

    Monolec Syn Multi-Vehicle ATF ensures smooth shifting, reduced wear on parts, longer fluid life and a significant decrease in maintenance costs.


    Lubrication Engineers operates under an ISO 9001 Certified Quality System.

    Heavy-Duty Formula Improves Equipment Performance

    Monolec® Drive Train Fluid (7511, 7531, 7551) is a high performance, heavy-duty drive train fluid that protects off-road equipment and keeps it in working order, whether it is running intermittently or continuously. It works with today’s newer transmission designs and can be used in final drives, wet brakes and various torque convertors. It improves power throughput density, helping reduce mechanical shudder and eliminate brake chatter and clutch wear. Ideal for use in construction, mining, quarries, hydraulic fracturing and other applications where downtime can be costly, this versatile fluid meets or exceeds the performance requirements of Caterpillar, Allison and Komatsu.

    This is not an engine oil formulated to be a drive train fluid; Monolec Drive Train Fluid was specifically developed to meet the rigorous demands of the application. Its carefully selected additive system – which includes Monolec®, LE’s exclusive wear-reducing additive – balances the need for lubricity along with the frictional properties needed to optimize the operation of powershift clutches and wet brakes. The fluid’s high-viscosity base oil helps it stay cool during operation – even in extreme temperatures – with no need for seasonal changeouts.
