It could be a few things. ASE mentioned the torque converter which is possible. Also, the torque converter clutch (TCC). Also, a throttle position sensor could be causing the issues or a vacuum leak.
The items I added would normally cause the check engine light to come on. If it has, have the computer scanned for trouble codes which can direct you to the problem. Most parts stores will do it for free.
Let us know if you have other questions.
