According to the operator’s manual as well as the Lexus dealer, my 2015 LS 460L includes a sealed transmission that will never require support or a fluid/filter shift. I typically drive 100,000 highway kilometres annually and expect to keep it for five decades. Are the specialists to be considered? — Cam
The days of one transmission fluid being used in numerous brands are gone, because most manufacturers now use high-spec fluids which are brand and model-specific. Sealing the transmission limits contamination of debris and curbs incorrect fluid top-ups from the do-it-yourselfers.
The Toyota World Standard (WS) fluid is regarded as a lifetime fluid when used under normal driving conditions. But your driving habits aren’t typical, putting your care needs in the “severe” category.
Walk into any transmission mechanic and you’ll notice transmissions from all manufacturers with life fluids being rebuilt well before the end of the vehicle’s usable life.
Mike Arbeau of Precise Transmission in Mississauga, Ont., says he generally recommends 100,000 kilometres as the maximum for any car and any driving condition. Warranty coverage ends for many vehicle owners in 100,000 kilometres. So if automobile manufacturers actually believed in their life fluids, they would raise the warranty on their products to reflect that belief.
