I also would rather have the 4500, but for those that prefer an automatic, a 4l80E can be made to survive behind a stockish 6BT. It was even used in stock applications behind the LB7 and LLY Duramax in the vans (well 4l85e...) Although the dmax was detuned, plenty of van guys have ran stock truck LB7 and LLY tunes with good results.
