The case looks good. Turns out the rollerized forward hub was machined just a bit over limits. I also see evidence of the direct making contact with the intermediate spring retainer and some slight contact marks on the forward hub from the direct having to much play. I didnt have the th400 retainer. And now I can see that the flimsy 4l80e one was starting to flare out. I'll be fixing the forward hub and use a spiral loc with a case saver this time around with the Th400 retainer. I'm almost considering not running the 2-1 band 🤔 thanks for the input

 

now that I see quite a bit. IME, thrust end play specs and clutch pack clearances is what separates the wheat from the chaff.

 

thrust endplay and clutch pack clearance separates the wheat from the cow **** in the field

that's standard, most basic, mandatory stuff for any quality build

wheat from chaff comes in the form of additional modification of the thrust paths, geartrain stabilization, and most importantly, hydraulic circuit integrity and especially in a 4l80e...extensive modification.
The 80e pump is ****. pressure regulation is ****, lockup circuit is ****. intermediate and OD circuits need work. the lube circuit is a mess. etc

 

Gee grady, you sure know a lot about Chickens, Eggs and Cow ****. Are you planning a Career Change?

 

I'd retire tomorrow if I could afford it!
