Dodge Repair: Tranny ?, turbine speed, mile warranty

Question
Hey i bought a car last friday used with 90,000 miles on it and got a 18,000 mile warranty with it. the warranty covers specifics such as (tranny- all internal lubricated parts, seals, gaskets, torque converter and transmission case) thats all thats listed on the page and i recently have started to experience a few problems when im driving it feels as though the car doesnt want to get out of certain gears and if ever i accelerate the rpms like hit 4 so i of course let off but its really worrying me, also after it gets out of gears i can feel it shiftin down with a jerk of the car as i'm going to a stop. I hooked up the check engine reader and got a few codes reading that the PCM has detected an incorrect gear ratio condition in a few of the gears. also i got one saying the pcm has determined that a malfunction exists in the input circuit for the turbine speed sensor. First i want to know if these would be covered because a week after buying a car i really hope i dont get stuck with repair costs and second i would like any suggestions or any ideas as to what it is and how it can be fixed. Thank you for your time and i apoligize for the novel....
