Sounds like your CVT to me. Might be time to trade that in.....while it is warm....
Engine over revving
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.

whoever told you the ABS light requires rewiring the car is a fool. The ABS wiring is integrated into the main harness...so unless they back-probed ALL the wires to their pins, they are talking out their ass. Take it somewhere else. A bad wheel speed sensor or two can cause the CVT to do funny things, as the CVT uses ABS wheel speed sensors as inputs to determine gear ratio and torque converter functions.
Take it somewhere and have it properly diagnosed, otherwise everyone is just guessing. Worth the $100 diag fee to get the right answer. And take it somewhere reputable and is familiar with Nissan CVT function. I recommend the dealership.

Make sure the transmission fluid level is correct.whoever told you the ABS light requires rewiring the car is a fool.
