Question about 1993 Toyota Corolla
-A 1993 toyota corolla, 1.8cc. Whenever i start driving the car, the O/D OFF signal appears on the dashboard. The car also change the first gear after maybe 0.2-0.3 miles after which its ok.
The problem is more persistent when its too hot. Funny enough, when it rains/cold, the O/D off sign doesnt appear at all and the car runs smoothly.
If i drive at high speed, 60-70mph, the car sometimes jerks as if shifting from gear D to D2 gear.
I did transmission service 7 months ago. Always change the oil on time. Also had the timing belt and starter changed 6 months ago.I have had the car for 3 yrs and has been perfect. The problem has been persistent for the last 2 months.
The O/D off means your overdrive is off. Have you accidently bumped it? It could be the start of a problem with electrical system. Usually a bad ground on your O/D may cause this. Intermitten problems are the hardest to track down and fix. Do you know what overdrive does? It's a gas savings device which cuts the engine's RPM's down by something like 1/3, like a 5th gear. That's why you are experiencing the jerking on the highway. Do you have an owners manual? If not a good place to look for one is at a local salvage yard, or online even. There may be something in there to explain this to you a little better than I did. I had a frien who had a simular problem. It turned out to be a bad fuse. It wasn't blown, it was broken, and it's element would jiggle around when he would hit bumps in the road. I don't know if this helped you, but it will give you place to start looking.
