Be careful. My friend has a new taco and hates all the shifting being done in the truck. He says it acts like it is always confused. He got it when Taco replaced its 4.0 with a the smaller V-6 engine. He wishes he had his old one back. check the shift points on when it shifts first if you can. I am not saying its bad but I always give a new engine and a new 9 speed transmission a couple of years to get the bugs out. His transmission also has a higher temp reading on the fluid since its constantly shifting. Just my thoughts from listening to my friends with downsized motors and more shift points. also I believe the new Nissan engine does have more horse power, but is now closer toward the bottom end of the torqe range of other midsize trucks now. check the Colorado and Ranger torque ratings. Horsepower is how fast you can go . torque is how quick you can get there and is made more for towing weight and off roading.. Just some thoughts. Everyone have a good day, and drive safe.
