Tranny problem
My trans works normally until warmed up. After shifting into park or turning it off for a bit, when i restart and shift to drive, it engages for a second then drops out of gear until I rev up a little then it engages hard and runs normally. If I start in first it engages fine. Is there an easy fix before I goto dealer? I've got an ext warranty. 2007 5.4, 41,000mi. Thanks.
