There are no codes, but tranny seems to have issue on down shift especially while i'm below 40mph. Slowing to stop light/sign hard shifts to lower gear. Basically it seem to be a lag in detecting I have slowed down. The speed output sensors have both been changed on the tranny already.(twice) . I have a 02 dodge Grandcaravan and any hellp would be greatly appreciated.

 

I'd say you need to have someone with a scanner check a thing called CVI (clutch volume index) This information will help in diagnosing the exact cause of your symptoms.
