    I have an 03 1500 silverado with 4L60. Sometimes when shifting from 1-2 to second I get a delayed shift. Its like it shifts but it doesnt lock in gear for a split second then it locks in. This does NOT happen in tow/haul mode. Any ideas what the problem is? Thanks.

    Sounds like the computer shift points are somehow jazzed. Dealer can clear them by plugging your truck in and then it will 're-learn' them. Sounds a lot like what I went through with my '02 for awhile after I had some tranny work done years back. Unnerving when it finally engages, ain't it?
