The advanced, nine-speed automatic transmission system was swamped with problems within the Honda and Acura lineups. Honda offered it with the 2015-2017 TLX, the 2016-2017 MDX, the 2016-2017 Pilot, and the 2018 Honda
Odyssey, where customers and service technicians reported problems such as gasket leaks, or improper transmission assembly causing coolant and transmission fluids to mix. These problems could lead to extreme overheating or total failure of the transmission.
The service bulletins Honda handed to their technicians detailed the problems and it was concluded that, in rare instances, cars under warranty needed their transmission, transmission warmer, radiator, thermostat, coolant hoses, coolant reserve tank, and O-rings replaced.
The 2019 Honda Pilot shouldn’t have any of these problems. The press release did not actually detail the changes to the transmission, but it was noted that along with the updates, Honda made “significant refinements to its 9-speed automatic transmission (available in Touring and Elite trims).”
The ZF 9HP 9-speed automatic transmission in the Pilot should also provide a bit more engaging experience as it was reprogrammed with new software. As always, it moves with the 3.5-liter V-6 that develops 280 horsepower.
