    Did you have your trans rebuilt, get a junkyard unit or a brand new unit?

    Also did you notice any difference at all between the old and the new tranny?

    the trans was rebuilt by aamco but they had new internals and the case was new. the only different i felt was a crisper shift due to new clutches

    I had this problem it turned to get "The fuel pump, cam sensor, and crack sensor" you may want to check those ?? but i would start off by first fixing the alternator
