I have a 2009 Nissan Altima 2.5 L, and every time I start the car, I step on the gas and accellerate, and the RPMS go way up to like 3000, while the speed only stays at like 15-20 mph. Idling is fine, cuz I'm not pressing on the gas. And also, as you're increasing in speed, you can feel it kinda jerk back, which I'm assumming is the auto shift down for some reason.
After driving a little bit, the thing I guess remembers to shift, and then it drives normal. And once it does that, it's fine as long as I keep the car on and running. Once I turn the engine off, it's reset and when I turn the car back on, same thing happens and the engine over revs.
It's been doing this for about 6 months, but it's been managable. But now it's becoming alot worse and my dad and I can't seem to figure out what the issue is.
The only thing that's of note is the ABS light is on, and I had it looked at, and they said all the wiring needs to be redone. I don't think the 2 problems are related, but you never know with this freaking car.
We are completely stumped.
