car hesitate and back pressure

I have a 95 Ford Contour,110,000 miles. It hesitates when I step on the gas pedal and I heard back pressure noise either in the exhaust system or in the engine. I took to a mechanic and he wanted to change my transmission. However, I think he wrong because the car showed this symptom even when it in park. Should this cause by something blocking the exhaust system or the fuel filter? What could it be?
Thanks

Do you hear it in neutral gear? The mechanic wouldn't change such an expensive part of the car if he wasn't sure.You could go to a transmission shop for a second opinion before you lay out big bucks.

Possible plugged catalytic converter. Have the exhaust system checked out also.
