Transmision on 2003 Ford Windstar

Just had my transmission replaced 3 weeks ago with a rebuilt one from the warrenty company. The Ford dealership did the job......I still have the same problem....Intermittently, either when hot or cold.....I get at kick from 1st into 2nd.Can be on the up shift or the down shift....Dealer said they also replaced two sensors (dont know which ones) that the replacement trans didnt come with
