I have a 97 Honda Civic DX sedan 4 speed automatic. I had a problem with the car idling up and down continuously from 1k to 2k. I took the throttle body off and cleaned every up and it stopped. However, now when it goes to shift into 3rd-4th gear it revs up to 4k and shifts really hard into the next gear. I've tried some lucas transmission fix but it didn't work. Also it idles a little above the one now as well. What could be causing this?

 

Anybody?

 

its slipping. time for a rebuild

 

Never use oil additives. Especially on Hondamatics, which REQUIRE Honda ATF.

Your idle issue isn't related to the auto tranny. Search the fluctuating idle threads.

For the tranny, I would first flush it and then put Honda ATF in. Then I would try adjusting the throttle kick down cable. Maybe you'll get lucky.

 

sounds like kick down cable to me, especially if you had the TB off...

 

do u try to clean the filter on the transmission

 

I was told by Honda that my transmission doesn't have a filter that can be changed.
