Description

Elf Tranself NFX 75W is a gear oil from the Tranself line for manual gearboxes in Renault-Nissan-Mitsubishi Alliance vehicles, synthetic according to its maker. It eases gear changes in cold weather and protects the synchronisers.

The oil meets API GL-4 and holds official Renault approvals for the SX, JXX, TLX, NDX, NDK1, PXX and DBx gearboxes, as well as MB 235.17 approval. According to the manufacturer’s data sheet, it replaces Tranself NFP and Tranself NFJ in these gearboxes.

Typical data-sheet figures: kinematic viscosity 6.5 mm²/s at 100 °C, viscosity index 168, pour point -45 °C. Available in packs from 1 to 208 litres.

Application

Manual gearboxes of the SX, JXX, TLX, NDX, NDK1, PXX and DBx families in Renault-Nissan-Mitsubishi vehicles.

Worth knowing

The data sheet presents this oil as the replacement for Tranself NFP 75W-80 and NFJ 75W-80, and the switch changes the marking on the can itself: there is no second number here, only the winter grade 75W. What this grade means in the SAE J306 table is explained in a separate article. Compared with Tranself NFP 75W-80, this oil is thinner: 31 against 36 mm²/s at 40 °C and 6.5 against 7.5 mm²/s at 100 °C, and its pour point is higher, -45 °C against -51 °C.

The data sheet describes the replacement in one direction only: NFX instead of NFP and NFJ. The NFX gearboxes include SX, NDK1 and DBx, which are not on the NFP list (JXX, NDX, PXX, TL4, TLX), so nothing covers a replacement the other way for them. The similar Mercedes-Benz codes are easy to confuse: among the Tranself oils only NFX has MB 235.17, while Tranself EP 80W carries MB 235.1, and that oil is a different SAE grade, with 11.5 mm²/s at 100 °C.
