So my new to me 2011 crv has a strange intermittent jerk when you let off the accelerator. I feel a very slight jerk lunging forward for a split second, typically letting off in 2nd or 3rd. Its very faint but im a little worried since my 505 000km 2009 crv didnt do this, at least not as pronounced. My 2011 is a FWD instead of the AWD but I don't see how that would make a difference.

I already changed the fluid with oem DW1 fluid and it wasn't dirty to begin with. Is this a quirk of the FWD transmissions or is there something wrong? Car has 180 000km on it.

So after more driving, I can confirm it only does it in 2nd gear. If I'm coming to a stop and let off the throttle, it's like the transmission is still going like a manual car and you can feel a very slight jolt. I only changed the fluid once (3 quarts) and its still not perfectly clean so other than changing it again I really don't know what this could be. Feels like 2nd gear is staying engaged longer than it should when slowing down. I looked into the pressure switches or maybe a valve is getting stuck but I don't want to just throw parts at it. Any advice?

Honda does recommend a 3x change, with a drive between, that should refresh approx 90% of the fluid.
Possibly one of the solenoid screens is partly plugged. There is a procedure in the service manual to test the shift solenoids.

I ordered gaskets for the solenoids and will be cleaning them along with 2 more drain and fills, thanks.

4WD and FWD are essentially the same transmission, only the 4WD has a transfer case. The issue maybe the torque converter clutch not fully or quickly disengaging, and could be a sticky solenoid.
And could be an internal problems too.

When I saw the title of this thread I thought it was about some jerk that worked on it for you. :LOL: :LOL:

Yes I was debating if I should swap the fwd transmission with my 2009 4wd but with everything having 505 000km, I think it's done it's job. Still works surprisingly well for original drivetrain, doesn't lurch forward like this 150k fwd one.. It's really a faint issue so if it doesn't get worse, I can just live with it as a quirk. The car appears like it sat for a while so maybe something just needs to get unstuck. Fluid still being a little dirty doesn't help either but I have receipts that it was done previously at around 90k. It's shifts and drives better than my 09 except for that little jerk/jolt when letting off.

Well I noticed an improvement after the second drain and fill but on the 3rd with about 100-200 miles in between changes, the transmission is perfect. I suspect the previous owner with the junkyard belt tensioner and alternator that I just replaced didn't want to go get the genuine honda fluid and probably had some generic ATF in the transmission.

Well bad news, I started feeling the kick again recently. It seems to happen more once everything is hot. It's much less noticeable with the new fluid but I still feel this little kick when I let off in 2nd gear slowing down. If I build up pressure by accelerating slightly and let off fast, it will do it. I'm not sure if I should start taking apart solenoids and cleaning screens or just live and see if it gets worse.

Since this seems to an issue with lower gears, I will order the gasket and piston o-oring for the solenoid assembly B and test it. The external transmission filter is still original so if I find a lot of deposits on the solenoid screens, I will replace the filter too.

Genuine Honda Fluid
I know it is expensive $ but all the others have trans fluid additives that they think are better than Genuine Honda Fluid
I did not like spending $ on 4 quarts of Honda fluid but was glad I did.
and
That 3 Honda shop fluid change is just to purge the old Honda fluid out of the system.
I did not do the Honda shop 3 fluid changes.
but
Due to the fact your have shift problems I would do the 3 fluid change with expensive $ Genuine Honda Fluid
Black Color
My 50,000 mile CVT oil change the removed old Honda factory fluid was black which is NBD. I found other posts that showed their honda CVT was also black in color on the first CVT oil change.

I did that already, it got better on the second fluid change and after the 3rd one, it seemed fixed but I started feeling the little jerk when I let off the throttle after accelerating. This is my father's car and he doesn't even feel it and the fact I daily drive a hybrid doesn't help because you drive differently and let off the throttle a lot after accelerating to engine the electric mode to coast. If I let off the gas on the CRV and apply the brakes right away, you don't really feel the kick. Is this maybe a software thing where honda made engine breaking more aggressive to save on gas? My 2009 did not do this that is why I see it as an issue but there are some minor differences with this newer 2011 and I'm wondering if the transmission software is the same.

Well unfortunately, this is my fathers car and after taking it for a long drive today, the jerking is still there when letting off the accelerator. I thought the 3x drain and fill fixed it but it only improved it. This only starts happening when the transmission is warmed up. Cold or even the first few miles you drive it, there is really no jerking when letting off the gas. The car drives so well otherwise and my father barely notices the jolting with the way he drives it but it's there. It does it most in bumper to bumper traffic when you accelerate momentarily and let off. It's really annoying because there is no code and it has done this since we purchased it, about 15k miles now.

I figured its more pronounced when I drive it because I let off the gas completely but when you modulate the pedal and just slowly let off, it won't jerk most of the time but this just doesn't feel normal. I really don't know what to check next or if I should just keep driving it and see if it gets worse because so far, with the fluid changed, it has only improved other than those specific times in bumper to bumper traffic or quickly letting off the gas. The shifts and downshifts are so smooth, you can barely feel them after the 3x drain and fill.

You mention "there is no code." Is this with your OBD II or a Honda dealer's computer scanner? Have you changed the external transmission filter yet? A fourth fluid change including the in line filter replacement seems necessary if you believe fluid other than DW-1 was previously added.

Fluid was changed 3 time with OEM DW-1. I still haven't changed the filter but was planning on changing it the next time its due. The transmission and engine are flawless otherwise. My 2011 does not have an EGR like the 2007-2009. I did a major service when I first got it and changed the spark plugs, cleaned the throttle body, new air filter, valve adjustment. The engine runs really well and very quiet, better than my previous 2009 CRV. This transmission issue feels like there is too much backlash somewhere at slow speeds, its hard to explain. At slow speeds, if you tap the gas a little and let off quickly, you will feel a little jolt in the drive train.

I used a CR629 LAUNCH OBD2 Scanner

I change my in-line trans. filter every 100K and the fluid has been changed every 20K starting at 5K. When I cut my filters open (215K now) they are filthy! Others mention this too! A block in the filter may poss. cause this issue you're having. The kicker is that Honda says this filter is not a servicable part. It is! A foreign non Honda fluid may also have already caused trans. damage?
