easy question here:

46re not shifting right, shift maunally, shifting gets worse as it gets hot... thats that!

I am going to replace the solenoid, transducer and lock up solenoid ( im i n there) My question is, should i drop the whole valve body and replace those parts too, while i am there? I am not tranny savy much, and i am hoping the first part is my fix.... its my around town truck, so im looking for a fix i can do myself....

note full tranny rebuild 60 k ago,
dropped pan, drained, no metal in pan,,, nothing unusual.....
