Description

77 Lubricants ATF L6S is a fully synthetic long-life fluid from the ATF line for ZF 6HP-series six-speed automatic gearboxes.

It holds no official approvals; the maker states that it meets the requirements of BMW M-1375.4 and BMW 83 22 0 142 516, GM Dexron VI, Ford MERCON LV, MB 236.12, VW G 055 005, Toyota WS, Nissan Matic S and Hyundai/Kia SP-IV.

Typical data-sheet figures: kinematic viscosity 5.8 mm²/s at 100 °C and 27.1 mm²/s at 40 °C, viscosity index 161, pour point -48 °C, flash point above 201 °C.

Application

ZF six-speed automatic gearboxes for which the car maker prescribes M-1375.4 fluid, and units designed for Dexron VI, MERCON LV or Toyota WS.

Worth knowing

When changing the fluid in newer ZF automatics, six-speed ones included, the gearbox maker refers you to the carmaker’s original-fluid number. The numbers that 77 Lubricants links to L6S are of exactly that kind: BMW M-1375.4 and 83 22 0 142 516, VW G 055 005 and the MB 236.12 sheet. What the VW number stands for is clear from another data sheet by the same maker: in the ATF LV list the number G 055 005 is given as ZF LifeguardFluid 6. The overview of ZF TE-ML codes and commercial-vehicle sheets explains where ZF draws the line between automatics for the 11A and 11B classes and gearboxes that take its own branded fluid, and at what mileage it advises changing that fluid.

The MB 236.15 sheet is not in the nine-entry L6S list. For gearboxes for which Mercedes-Benz specifies exactly this sheet, the match in the ATF line is, among others, ATF MBS: MB 236.15 is the only one in its list, and it is also claimed for ATF LV, LV Red and L8S.
