Thanks for keeping us updated! I'm glad to hear that this may work out fairly well for you.
I'm in the middle of a search for my next TV and the Sub 2500 is high on my list. Sounds like the transmission behind the big block is somewhat prone to breaking like the 4r100 is in the Ford Excursion.
Do you know if there are any high performance transmission builders for the GM (4l80e???) transmission like there is for the Fords. I know that Brian's Transmission Shop is a well regarded builder of the Ford transmissions for towing applications but wasn't sure abot the GM.
Thanks!
Jeremiah
