It sounds like you have a struck injector. how is the engine running? Can you please shoot a quick video with your phone so we can see what's going on? that would be great. You can upload it here with your response.

I changed the injectors, cam sensor, EGR valve, TP sensor and the computer. but the problem of emitting black smoke is not changing.

The same car the CVT gearbox not changing gears its like it is stuck in one gear.I removed the gearbox and put it on another car it is driving perfectly well.took a gearbox that was driving well and changing gears I put it on this car and it is not changing gears what could be the problem

Hmm, it could be the catalytic converter is partially clogged causing both issues but to confirm the issue here is a guide.
