Engine Braking/Down Shift Problem - 8thAccord

sparky · 03-17-2008, 02:35 PM

I've my my accord for a week now and was going down a pretty steep hill. I wasn't accelerating or braking but notice the down shift and the engine braking, RPM then went up to 4. I tried to give it a little acceleration but nothing really changed. Is the new accord suppose to do this? Is it because of the logic control. It was a short decend I'd have to try it more just want to know if anyone else notice/encounter this. Thank you for the inputs.

I have a 4 cyl. 5AT 4 Door.

Personally I drive i4 M/T Coupe.

Seems a bit of some odd behavior for A/T though. Have you gone up this hill again, did it do the same thing?

You might be able to find some better answers at driveaccord.net

I find that forum to be quicker with responses/more informative than this.

No offense 8th!

Yes the new Accord will downshift on hills to help hold back the vehile. Set your cruise and it will do its best to not let the car go more than 5 over the set speed. Also the shift hold feature may be kicking in also. The AT on these cars is very smart, so much so I am not as inclined to overide it like older cars.

Thanks for the reply.
Went to the same hill twice and it didn't happen again. I'm guessing the engine wasn't fully warmed, and I remember reading somewhere in the user manual that the engine might hold certain gears to speed up the warm up process.

When ever you go downhill, engine brake will engage.
I drive down hills every day... (about 45'-60' angle. very steep.) and it happens to me all the time.
So don't worry and have fun with your car!

driveaccord.net people talk trash to 8th gen accord. They do not like this or that of 8th gen.. thus, i do not go there any more.
No offense to them!

from my experience, the automatic transmission downshifts whenever you don't press the gas and the car speed deccelerates below some levels for each gear. It does this so that when you decide to accelerate again it will be already in the correct gear and it would not need to downshift after you press the gas pedal again.
Regarding the hill assist feature, I think that its only for going uphill. I think that the tranny downshift and sticks to that gear for a little longer that if the road was level so that it will not have to upshift and downshift again if the road is too steep. I don't think that it has to do with going downhill as the Land Rover and BMW X series transmission feature.

This also happens in the newer Civics. I've noticed this several times. I'm glad I don't have a stick shift for my daily driving, but on longer trips, it does get annoying that the car shifts pretty much when it feels like it.

I guess I'm just not use to it. I was just trying to be careful during the engine break-in period. Things are better now.

This is a feature of the car. it's called Grade Logic Control.
