When did you last do transmission maintenance and all the info should be on the under side of the hood.

 

what kind of tranny maintence u talking not sure if i change the tranny filter if that will take care of problem.

 

tranny fluid is not dirty or burnt

 

manual trans? you stated clutch? if so throw out bearring is what it sounds like to me.

 

no its an automatic 4 speed i said clutch because not sure why it whistles when it does shift

 

re-read it sounds like an auto. Sorry, Same thing was going on with my 2000 ram took it in had it flushed next day going down the road it acted like it went into nuetral, 2200.00 lated I was putting in a new one. Good luck..

 

tranny seems to be strong but its the shifting thats the issue

 

stll lookin 4 any idea's on what it could b causing this problem

 

I'd check for vacuum leaks on the engine. Not only do they whistle, but they can cause shift delays.
