My car went in limp mode. So I start checking online for some help because I did not get any codes. After founding a seller(USA transmission parts) I called to tell them about the symptoms. So they told me I need a new TCM (built in the transmission on the valve body) and that it was a common problem. So I bought one and after installing it, the car is accelerating very poor. Wont even go in the manumatic position. I am from Surinam (small country in south America) where there are no Infiniti dealers that I could call. So I found you guys when I was browsing on the internet. Please help!

Unfortunately you will have to have the TCM programmed to your car which a mechanic if he has a professional scanner may be able to do.

Thanks ken, but I did it already. The funny part is that all the codes have been erased, but the vehicle is still accelerating poor on p(park) didn't drive it to find out cause to afraid of driving it in the position it is right now. I have a live data picture attached so you can see what I mean. The picture is a live data of the transmission.
