2001 Honda CRV automatic is not shifting gears as it should, it will stay in second or third until I let off the gas a bit. Today was traveling on
a highway and with cruise control on was going 65, then it dropped a gear and stayed at 4000 rpms until I turned Cruise control off, took foot off gas pedal very briefly, then it worked okay for a while.


Check engine light indicates loss of emission something or other, clear the code and it comes back. Not sure if changing all O2 sensors and PCV would fit that also. new pcv would not hurt anything.

I known the two problems are probably not inter-related.

Added note: I did put some Sea Foam Transmission cleaning fluid in to see it that helped shifting. I know it probably needs fluid changed anyway. It seemed to help for a while anyway.

Yes please, change the transmission fluid.

I checked with the local Honda dealer, @$160. just to drain and refill (3.1 qts) or ca $280.00 to completely drain, clean and refill, ca 12 qts).
Local lube shops charge $100 and who know what they do, if anything at all!
If I had stands I guess I could do it myself, but I don't. 1 quart is about $10.00, so @$120.00 for full change and then @$160 labor?

If you have access to an OBDII reader (or Scangauge or Torque phone app) verify that your engine is staying warm.

The dash gauge is 'dampened' and if the coolant temp drops (not visible on the gauge) your ECU will hold lower gears as if the engine was still warming up.

++++++++++++++

I agree with changing the ATF just as Good Practice.

Rather than pay dealer labor prices, see if there is a Honda SPECIALIST near you (who knows the importance of factory-spec fluid). Or, ask at a corner garage if you could bring your own fluids.



You could buy ramps for the money you save in labor costs. :applause:

Just talked to Honda Specialist I didn't know was in the area, he does not think the fluid has anything to do with the problem, suggest I take it in for them to look at it. not a bad idea. Guessing doesnt't do much good unless it is intellegent guessing.

First thing:

Don't need stands to do a fluid change on gen 1 or gen 2 CRVs. If your scared to get a little dirt on your back get a peice of cardboard. Takes 10 minutes to change, no stands or jack needed. Never used them in my 2003 which has more crap in the way.

Secondly: What your experiencing isnt isolated. Fluid CAN fix it but may not if the problem internal. I know this because I experience the same thing.

Changes is weather, amount of weight, head vs tail wind and tire pressures can do this as well.

Also EMISSIONS CODES WILL DO THIS (yeap my evap canister valve has taken a crap and dealing with this annoying issue again till I replace the valve)

What your experiencing is an overly cautious computer program that engages when cruise is active. Not sure why Honda have the shift point and other transmission settings change when cruise is on instead of simply holding the throttle at speed, BUT IT DOES. Annoying as hell.

Now an internal transmission issue can cause this too if wear and age has caused pressures to not be AS HIGH as they should, computer sees this and plays it safe. Especially when cold out.

Fix the emissions codes first then see where your at. If you find it to annoying after that, plan on another transmission at some point. I'm hopefully picking up my buildable core in the next week or so just so I have it (will start rebuilding it as I work at a transmission shop) as mine has 223k and I dont drive like a grandma.

When I talked to the Honda Specialist he indicated that some thing other than the fluid was more than likely the culprit, I could take it is and they would check. I took it is yesterday to make arrangement for that. He (the same person I talked to before) looked at the fluid on the dipstick and noticed it was dark, a bit dirty, but not burnt. Hw took it for a test drive and said he would n't worry about the shifting-- even though it hangs up between 2-3, and 3-4. It will go to about 4k rooms and stay there and not shift. But sometimes it does shift okay. They are going to change the entire fluid Friday. Had an oil change yesterday also.

I took the CRV in for a transmission fluid change this morning. Completer change, not just 3.1 quarts. It cost a bit more than the dealer stated. The old fluid was real dark, darker than the worker said he ever saw before. While there we noticed a radiator leak that need attention- but not today. He looked over the exhaust system and noticed a rattle in the converter, probably the rattle I hear when starting the engine. He is certain is something inside broke loose and is partially plugging the path of exhaust. That is interfering with the engine operating and not allowing it to shift gears properly. So back in next week!

Just an added note: I saw a video of a man using SeaFoam converter cleaner to clean his converter. But instead of putting it in the gas tank, he removes the front O2 sensor, sprays some Sea From in - but he never stated how much, looked like maybe three to five squirts- and then replaced the sensor, he let it sit a while then started the engine. White smile for a while, but in the snowy parking lot you could see black residue from the converter. the mechanic today said he does the same with whatever cleaner they use.

okay, I thought I had responded before, but I guess it didn't go. I see I did , it just didn't show, now I don't know how to delete this post!

Cannot tell ylouin that the completer flush did it., the cat converter was bad and caused pressure to back up.
