Last, but not least, ZF also made a big fuss by saying that this 9-speed transmission is up to 16% more fuel efficient compared to the outgoing 6-speed unit. 16% might be a bit of a stretch, but the 9-speed is indeed more efficient compared to all older ZF automatic transmissions. How Reliable Is the ZF 9-Speed Transmission? When the new ZF 9

The 9HP transmission has nine forward gears and a spread of 9.81. To illustrate: At 1000 rpm the vehicle 'crawls' at around 7 km /h in first gear or it rolls over the motorway at 120 km /h with casual 2000 tours in ninth gear. Achim Hartmann. The Jeep Renegade was one of the first cars to drive the ZF 9HP.

What ZF is doing with the 9HP for transverse mount applications (which accounts for 80% of current car production) is leapfrogging the six speed competition with three extra speeds. And ZF isn't

The total spread is 9.81 which significantly reduces the engine speed and thus also fuel consumption. The transmission has a harmonic step range like ZF's 8-speed automatic transmission (8HP) - the wheelset efficiencies of the planetary gearset rise above 97% in all gears.

It now accelerates smoothly but in the last few months, on four occasions has died for five seconds after taking a corner.

This is because the ZF 9HP was introduced in the TLX before it started appearing in other acura/honda models. It's still being used in MDX, Ridgeline, & Pilot. Sure they will get the 10 speed soon. Point is that honda used this AT for a while. There are still lot of mystery to the 9 speed, some like em, most hate em, etc etc.

My van's transmission was replaced at 54,000 miles in June 2020 after several attempts at resetting software. I wasn't stranded because of it, I just had the transmission adaptations reset about every 10,000 miles when it started having the 15 mph jolt again.

It's all down to the clutches. While a traditional automatic uses friction clutches in the form of either band clutches or multi-plate friction clutches, the 9HP blends friction clutches and dog clutches in the same transmission case. Dog clutches are "interference" clutches more commonly found in manual transmissions and transfer cases.
