Toyota Corolla Transmission Questions
Here is the background info. I added some gumout fuel injector cleaner to my gasoline after changing the oil, but put in twice the amount needed by accident. Immediately after, when i pressed the gas pedal, the rpms would hit somewhere between 2 and 3k before first gear would catch... Above first gear, there has not been any catching or rough shifting at all. I drove until the tank was empty. I asked around about the concequences of this and was convinced my car would be ok. After refueling, the car ran a little better. I then disconnected my battery to reset my computer and changed my spark plugs which has helped but did not fix the problem. The first gear is still catching slighty it seems when I am driving at low speeds or starting... I do know that I need a new catalytic converter, but have put off the $400 repair. I am skeptical that it is the transmission because the problem seems to be going away gradually. Next on my list is changing the air filter, and maybe some seafoam... Any ideas, hints or similar experiences??? Any help is appreciated.
