I replaced the transmission on this car listed above coupe and now i have the at check light and when in drive it feels very sluggish when accelerating into first gear then slowly gains power on second but doesn't seem to shift correctly. this transmission has 40,000 and is out of a 2006 coupe. both have single plugs. is there a possibility TCM needs to get reprogrammed?

Hi, I'm Dan.

Short answer is yes, the VIN must be programmed to the replacement Transmission's TCM. (Trans Control Module). Most likely this will require a Nissan Factory scan tool.
I've also attached a TCM code list for the transmission. Check for codes in the trans and the engine to see if you have any communications codes.
