The car when driven shifts through the gears smoothly when taking off from parked to 60 MPH. The problem occurs as you slow down from 60 to 35/40mph. Once at this speed, I attempt to accelerate and all that happens is the rpms rev way up but it seems to be stuck at 40mph. If i put it to the floor the car red lines and will lurch forward and slow down and lurch again and slow down... I brought the car to Nissan dealership and they acknowledged the problem, diagnosed it as an internnal transmission problem, and since its under factory warranty, put a new transmission in it at no cost to me. On my drive home I noticed that the car is doing the exact same thing I described. I turned around and brought it back and explained this to them. They said for 75$ they would run a diagnostic on it and try and figure out the problem. Still waiting to hear back since that was this morning. My question I guess is, does anyone know what this problem could be? I am a female and am feeling like they are giving me the run around and I would like a little knowledge about this problem so i could atleast understand what's going on. Any information would be helpful!
First of all, if they swapped the transmission and they want to charge you $75 for a code scan for the original problem, get on the phone with Nissan Regional management, because that's BS, they should not do that.

there is a service bulletin (NTB11-089) that says:

2007-2012 NISSAN MAXIMA; LOW POWER 0-40 MPH
Vehicle has low power 0-40 mph, and Power is normal above 40 mph,
and There are no DTCs stored. (meaning check engine light is not on).

ACTION
Before doing any other diagnostics or repair,
Inspect (and if needed) repair the ABS/VDC wheel speed sensors/signals.
• Refer to the Service Manual as needed.
• Perform “line graph” diagnostics on each sensor while driving. Inspect and repair as needed any sensor with a spike in the output signal or that has a different value than the other sensors.
NOTE:
• The most likely cause of the above concern is an issue (sensor, wiring, or debris on sensor/rotor) with the output signal from an ABS/VDC wheel speed sensor.
• A weak or erratic output signal from a wheel speed sensor can cause poor performance or lack of power from a stop, or at low speeds.
• Do not replace the TCM or CVT unit when repair of a signal from a wheel speed sensor will resolve the issue.

(The CVT is the transmission and the TCM is the computer that controls the transmission)
