My truck is up and running again with a built 4L60. I know I should have put an 80 in, but I didn't want to sacrifice the power.
Allen turned up all my line pressures so this thing is shifting really hard.
The work was done at Eagle Transmission in Austin, TX. I couldn't be happier at this point. $1428 for a complete re-build including:
1. Rebuilt Convert that stalls a little higher
2. New bands
3. New Drum
4. Redline Clutches
5. Beast Shell
6. Transgo HD Shift Kit
7. Labor on Rebuild, Modifying the Drum and Valve Body
I can't wait to get a new tune and get to the track!
