2004 t and c tranny issue
 

I have had my town and country for about a year now and have enjoyed greatly, however recently it has developed a problem. from first to second and only then it feels like it shutters or shifts back and forth between first and second. the tps has been changed and I am changing the plugs and cables today. any ideas? from 2nd to 3rd and 3rd to overdrive all is fine. thanks for any info!

fluid look good?

both fluid color and level are good, thank you.

get the codes from the transmission computer
