2000 Dodge Stratus transmission problems?

When I am driving it feels like the transmission slips and car will jerk, sometimes it will do this multiple times and other times it may do it once or twice during my 50 mile trip to work. It does seem to do it more often when the weather is hot, as in the mornings on my way to work it may do it a couple times then on my way home in afternoon it may do it 10 to 15 times.I just replaced the tranny filter and fluid using atf +4 but it still does it. Like I said it feels like the tranny is slipping when it does it. Should I disconnect battery to reset computer? Maybe replace tcm or solenoid?Other than this it seems to run pretty well and seems to mostly do it during cruising speeds or on hills. Thankyou
