Sorry - not sure why I don't always get the updates.
I pickup the engine/trans on Wednesday.
I *think* I am at least going to bench tear it down and organize each section into their own seperate plastic buckets.
I will inspect the hardparts as well as the fluid. If everything looks ok I will probably
1) Increase the 3/4 clutch count and maybe new clutches depending as it just requires a screwdriver I believe
2) Validate the 5 pinion sun gear - I believe the 4l65e already has it though
3) Add a Sonnax Servo and do a transgo VB upgrade and new 2/3 band
4) replace shaft and tailhousing and get a new VSS
Since the truck will only be stock lq4 (Around 275 RWHP) think this will be enough for now.
Later ....... if I add a cam I'll tear into it again if needed and/or do a 4l80e swap.
Something like that - but still researching and subject to change
Seems like a good way to tear into trans and get what I need without much cost. Learn for the next one - which is about 50/50% chance of being 2 weeks after I start driving it if I miss something
I'll start a thread both here and at LS1TECH if I pull the pin. Figure only one way to learn.
