I'm looking for some advice. I'm having issues with my car. Woke up this morning to go to work warmed it up for a bit then when i went to leave speed wouldn't not go past 5km and engine light is on.. I just for a brand new tranny put in 2 months ago.. HELP....

It to your local Nissan dealership

Sounds like limp mode. Get the CEL (check engine light) scanned.

I agree with the last post. A quick scan will help pinpoint what system is at fault. In temperatures in and around the -5 to +2-3 degrees, when ambient humidity is high there can sometimes be a buildup of moisture/condensation at the throttle body. This can sometimes make the throttle plate stick momentarily from frost/ice and cause the vehicle to immediately go into "limp mode" when equipped with an electric throttle (not cable actuated). The computer does this as a fail safe. The throttle is likely just iced up a bit. Just a guess anyway. If you shut off the car, wait a while and try again and the problem is no longer prevalent, this is likely all it is. Either way, please see a qualified tech to have the car examined. Imagine this happening at a busy intersection, railway crossing or miles out of town...

I have an appointment with Nissan on Friday just wanted to see what you all thought might be the problem.

With so many electronics it can be anything from a bad sensor to an abnormal voltage reading. If a vehicle enters limp mode there is a serious enough issue (to protect it from further damage).  
 
It’s really a crap shoot without the actual codes. I am just taking a guess a sensor was out of operating range.

I think you'll find that gearhead52 hit the nail on the head. I used to have this problem with a trailblazer at this time of year. Getting it into a heated garage overnight should resolve the issue.
