Hi there. The difficulty starting and lack of power could be fuel starvation caused by, a faulty fuel pump, a faulty fuel pressure regulator, or a restricted/plugged fuel filter. There is also the possibility of a restricted exhaust, ie; a restricted/plugged catalytic converter. The engine performance concern needs to be addressed before any transmission diagnoses can be performed. There several other possibilities for hard starting and a lack of power. Replacing components without proper diagnoses, can be expensive and time consuming without resolution. I recommend having your vehicle's slow to accelerate be diagnosed and repaired by a certified technician, such as one from YourMechanic.
