My car has no problem from take off but right after it seems to bog down then once it gets to where it's time to shift it acts like it doesn't want to but if I let off the gas it will shift but then the power is gone again I thought it might be the transmission but it does it if I put it in 1st 2 nd or 3rd gear but no problem in N I have tried a new mass air flow sensor and new fuel filter what could be my problem thanks for any help
