[SPEKTRUM]

so lately i have notice something very strange about my 2000 focus zx3 and im looking for some experienced input. when i make a rolling stop with the car and then accelerate the engine revs up and the car starts moving slowly and then a squeak sound and all the power comes at once. its very strange and i'm thinking it could be a bearing binding, torque converter malfunction, shift solenoid issue or its just not able to pick a gear for the speed im goin and has trouble coming out of coast. any input or possible fix advice would be great. thanks
