Description

Castrol TRANSMAX Dual is a fully synthetic fluid for dual-clutch transmissions with wet clutches. It is the factory fill in Audi and VW units where TL 52529 is specified.

Its single official approval is VW TL 52529. Castrol also states that it meets the requirements of VW TL 52182 and of six-speed VW/SEAT/Skoda DSG gearboxes, of Getrag units to Ford WSS-M2C936-A, PSA 9734 52 and Volvo DCT, and of Chrysler DCT and Mitsubishi Dia Queen SSTF-1.

Typical figures: 7.2 mm²/s at 100 °C, viscosity index 166, pour point -72 °C.

Application

Wet dual-clutch gearboxes: Audi and VW units where TL 52529 is specified, six-speed VW Group DSG units, and Getrag-based gearboxes in Ford, PSA, Volvo, Mitsubishi and European Chrysler models.

Worth knowing

The VW TL 52529 page lists three fluids, and only TRANSMAX Dual has this code recorded as an approval. Castrol puts the “Approved” mark beside it alone, while VW TL 52182 (G 052 182), PSA 9734 52 for Getrag gearboxes in Peugeot, and Ford WSS-M2C936-A stand under the heading “Suitable for use in”. So for a gearbox that requires TL 52182, the fluid is backed not by a Volkswagen approval but by Castrol’s own statement. Where approvals are checked, and why a fluid maker’s statement can be checked nowhere, is covered in the article on how to check an approval: “approved”, “meets” and “recommended”.

This fluid shares no code with TRANSMAX CVT and the three ATFs of the range. Sharing a viscosity of 7.2 mm²/s at 100 °C with TRANSMAX ATF DX III Multivehicle changes nothing: the DX III list consists of approvals, mostly for heavy commercial-vehicle automatics, and of statements such as GM Dexron III-H and Ford MERCON.
