Why does FUCHS not have a product approved according to VOITH H55.6336.xx?
Actually, our products TITAN ATF 1 and TITAN ATF 5500 were both approved according to VOITH H55.6336.xx for years. VOITH had an extra section in the this approval list for products suitable for extended oil drain intervals (up to 180,000 km instead of the standard 120,000 km). This section was later split off in the independent approval list VOITH 150.014524.xx.
Since then, our products TITAN ATF 1 and TITAN ATF 5500 have been included in this new approval list. Unfortunately, it is not possible to be named with one product on different approval lists. Only the naming on one single list is possible. Since VOITH 150.014524.xx covers VOITH H55.6336.xx, the named products carry the corresponding recommendation for VOITH H55.6336.xx and can be used for these applications.
Are the corresponding FUCHS products approved for initial filling by the vehicle manufacturer / OEM?
TITAN ATF 1 is also approved for the initial filling of DIWA transmissions by the respective vehicle manufacturer. This ensures that the CO2 emissions and fuel consumption determined in accordance with European Union Regulation 2017/2400 for the type approval of heavy commercial vehicles can be met.
Are the corresponding FUCHS products approved for DIWA transmissions with angle drive?
TITAN ATF 1 has been specifically approved for use in DIWA transmissions with angle drive.
