Does anyone know the shift speeds for the higher gears, especially 7-8 and 8-9? It's very hard to tell. It seems our mileage is better at 73-75 than at 70-72. Not complaining, just curious!

I can now display current gear on my ScanGauge. Next chance I get on the road I'll check it out. I usually see 8th around town on speed limits of 45 and 50, but will try a slow acceleration to see when those 2 actually shifts.

With a very light throttle, 7-8 @ 48 mph, 8-9 @ 65 mph.

That 7-8 shift at light throttle is where my transmission makes that "rumble strip" noise which, according to Honda, is a normal characteristic with PPs that have a transmission cooler. I meet with a Honda rep and an arbiter Dec. 3 to try to get Honda to do something about it.

I heard about that. Weird! Only thing I could think of was maybe cavitation in the lines.

Thanks! Wonder why our mileage is better at a higher speed. Yes, comparing apples to apples on the same stretches of interstate in similar conditions.

Cavitation may well be the reason. Looking fwd to getting answers from Honda.

Engine RPM is lower at 9th gear at your posted speed(s) than lower gear(s) at your posted lower speed(s)

Heh? The speeds the OP listed would indicate he is always in 9th. (73-75 than at 70-72.)
But if strictly going by the dash indications, I wouldn't put a lot of faith in those numbers.

That's why I asked. Thought it was odd, but remember someone said they thought the shift points were at higher speed. To reiterate, comparing apples to apples, same roads (flat I-95 in NC, SC, GA), different average speeds, using the dash calculator. More than once we've had better mileage going a bit faster.

Areodynamics???
Earlier on, no one could come up with why the PP mpg was 1 less than the Pilot, other than 1 more inch of clearance.
Maybe different turbulence.
Just how much difference is actually being reported?

The only other reference to a 8-9 shift I've heard of was the Jeep use of the ZF - something around 90+ mph.

Could you please post the ScanGauge codes for current gear?
Thanks!
