I had scheduled an appointment today at Infiniti service department due to the same problems a lot of people on here seem to be experiencing.
Seemed like the RPM was flaring and shifting awkward as well as that popping feel when it's searching for the gear.
I happened to see the TSB posted in one of the threads here so took that with me.
They had not heard of it, so I showed it to the service manager, he was very interested in it.
Anyways a couple of hours later I get a call that they are going to have to keep my vehicle over night.
They said whenever they took the car to the back, the engine service light was on, and now they have to replace the ECU, Engine Computer. (The engine light had not been on any time prior)
They also said that the TSB did not pertain to my vehicle...
Just wondering what peoples thoughts are on this? I'm worried as I'm sure everyone is that this is going to be an on going problem.
I'm supposed to have the car back tomorrow, so we'll see.
