Rollerizing the case on a 4l80e Question I am gonna rollerize the case bushing on my 4l80e with the popular TH350 roller bearing. From what I have read is the 97 and later use a feed tube to lube the rear case bushing and some people recommend changing it to the older style by swapping out the shafts so it will force lube through the shaft. Which sounds good but is this really necessary?
This is a daily driver so dependability is important.
Thanks for any help.

Drive the output shaft bushing slightly forward (towards bellhousing) about .050" to center the th350 pump bearing.
Use th350 pump shims to set endplay.
No need to change shafts, that's it. Easy Peasy
