Hi guys, new member here. I have been looking for threads similiar to what I'm experiencing but couldn't come across one. So I'm posting here. So maybe a week ago, my 2005 honda civic lx (almost 169,00 miles) did this sudden jump where i was going about 20 mph and my rpms jumped from like 2-4. Since then, the car has only been able to get up to like 25 mph-35 mph but the rpms will continue to rise. I have a video of the issue that I can send if needed. I just changed out my evap canister purge valve for a P0497 code that I got. Since then the check engine light has turned off, but in regards to what is going on, there isn't any check engine light on. Any help would be greatly appreciated . I can change out parts but I'm not really car savvy tbh.

Is this a manual trans? It almost sounds like your clutch is slipping. Same could apply to torque converter. May throw a code but I can't say for certain.

It is an automatic, sorry for not stating in original post. And that is something someone else told me was the torque converter. I'm thinking of doing a transmission fluid flush and if that doesn't fix the issue, you think it's most likely the torque converter?

Start with the fluid and go from there. Do you know if it’s ever been done?

Well it's my fiance's vehicle. So I know for at least the last 3 years nothing has been done as far as the transmission fluid. Should I just refill with more tran fluid or do a full fluid flush? I watched a video on YouTube and it seems like it's pretty simple to do. Thanks again for replying. The car is our only way to work and we got kids so I really gotta find a way to fix it so we can get to work.

Do not flush. Drain three times and refill. Drive a few miles in between changes.

Sorry, what do you mean by drain it 3 times? Do you have like a video you could link me just so I can know what you mean? Like fill it with tran fluid, drive it for a bit, then drain, and repeat 2 more times?

oh nvm i see what you're saying. so how many quarts should i be putting in when i drain? i think i read 3 quarts?

That sounds roughly correct. I don’t know the exact number so I’d triple check via a thread or some other medium.

I will double check but I appreciate your help!

You could first check the trans fluid level, it may be low.

Use only OEM Honda DW-1 ATF for best results. These transmissions are cranky with other brands of ATF.

What you may be experiencing is flaring which can be as a result of clutch debris clogging the internal screens and filter and affecting the ATF flow to shift gears. Recommended maintenance is a drain and fill of ATF every 30K miles or for those that have experienced Honda transmission failures in the past, a drain and fill every 3rd oil change.

Yeah tran fluid is definitely low.

I am gonna try the drain and fill. I just gotta get the fluid and such and then I'll be able to do it.
