Hello to all

I'am in dieing need of help, I have a 98 Infiniti qx4 4wheel drive and I have the code issue p0731 but here is the thing, when I try putting it in reverse it doesn't go it almost seem as if its going in park instead

Example: if the car is at a slow roll and I put it in reverse it will lock up instead almost as if u are putting it in park and not reverse.

Another thing that Is happening is that when I put the vehicle in (N) neutral it will be in drive instead also the vehicle will not even roll backwards when in reverse it will not roll in reverse period unless I turn t vehicle of completely while leaving the key to the on position but not to start the vehicle its also sluggish when accelerating from a complete stop it seems like its stuck in second gear also it doesn't even shift while driving just constantly one gear maybe 2nd or 3rd

I had a 2002 envoy that did the same thing. My first suggestion is to check the trans fluid level. If it is at the right level and is the right type of fluid the next suggestion is to look and see if the linkage is bent worn or broken. If that is not the case and the fluid smells burnt might get lucky and I say really lucky and change filter and fluid. My honest opinion is that you need to pull the transmission and look at the sun shell and replace clutches and plates.
