You're welcome... glad to help.

Is it normal for the car to shift up to 2nd gear very quickly? In both auto and using the paddle shifters the car will upshift to 2nd gear almost immediately from a complete stop. I don't think it will even hit 3k rpm. I have not trying flooring it from a stop yet because there is only 400kms on the car and wanted to "break it in" without any full throttle application s.

It will shift quickly... if you think about it, it's a 10 speed so with that many gears there probably will be a lot of shifting. I have the gear ratios I found online at home but couldn't find anything for gear/speed for this transmission. I can post that chart when I get back home if you're interested.

Thanks again for the reply. I'm familiar with 10 spd transmissions, I have a 2018 f150 Ecoboost with a 10 speed transmission.

I was more thinking along the lines of it being a built in break in procedure or something. It will go through the revs in every other gear except 1st. It will never rev up in 1st, like I said before I haven't tried flooring it yet. It feels really weird how it shifts to 2nd really early (2500 rpm approx). It shifts that way every time regardless how much throttle you apply.

Never paid attention to what RPM each gear was shifting but have noticed a lot of shifting and attributed it to the 10 speed transmission. Some have complained about rough shifting but you're the first that I can remember mentioning about it shifting earlier in 1st gear. Doubt it's a break-in thing as I can say I haven't noticed any difference since first owning my car.... IMO I would think it has to do w/the gear ratios... if you notice in the chart I posted the biggest difference between the gear ratio's is from 1st to 2nd. All gears after that the ratio's are closer.... my thought is that 1st is geared so low it is some built in mechanism to prevent it from revving to high and shifting it early. But that's just my WAG. :grin:

If you use too much throttle in first you'll just spin the wheels.
It's a pretty low gear. Shifting out of 1st early may be Honda's attempt to lessen the wheel spinning.

10sp vs 6sp have very different gearing ratios. First gear on the 10sp is VERY low. Second gear on the 10sp is virtually identical to first gear on the 6sp. It's going to shift out of first right away because the car is already moving so it's easier for second to do it's job than it is for first in a 6sp to get the same car rolling from a dead stop. I can't remember now which vehicle, maybe a pickup truck from the big three, is programmed for the new models to start in second gear for that very reason and will only use first if you are towing or do some tricks with settings to force it into first. It's doing what it's supposed to by getting rolling and shifting up.

Here's an article about the 10 speed tranny. 7 - 10th gear are overdrive.

First gear is crazy low on that car. Second gear is lower than the first on my 2009 V6. I don't understand why it needs to be so low, and I bet it never engages in ECON mode.

Maybe spinning it up would violate the EPA test cycle. If that's true some hacker needs to work on that. OTOH I'd be happy if I could lock it out altogether.

Quick shift out of 1st is more likely due to full torque being available at 1500 rpm which is 10 mph in 2nd.
Suspect there is not much torque below that (note where flashpro & ktuner curves start) - thus the extra low 1st gets her going until full torque is available

That makes sense. Maybe first gear is low enough that you don't notice turbo lag. OTOH the car starts fine in second gear manual mode. I'm not drag racing it and I do a lot of winter driving, so if there's a lot of wheel spin in first gear that's too low for me. I'd like to be able to lock it out without going into manual mode, which The Woman Of My Dreams will never be able to figure out.

Latest flashpro update has a traction control feature that should be a major help in controlling starts on slippery surfaces.
Would prefer LSD but this might be a worthwhile alternative.

What is flashpro? Is that an aftermarket thing or something the dealer will do?

Flash Pro is an aftermarket re-programmer for the ECU. it will alter the timing, turbo boost, and fuel mixture to provide more horsepower and torque. Your car will be faster with no other modifications. The downside is this will void your Powertrain warranty. This type of mod has become very popular for use on turbocharged cars.

I'm not doing that. This Accord is our commuter and I'm not voiding the warranty, especially since my only complaint is that first gear is sometimes too low in the winter. Thanks for the info.

First Gear is Very Low , this is Mostly a Trans Protection Gear especially if Towing ~
