Gonna tare down my 4l60e this weekend start figuring out what if any hard parts are needed. This will be the first 4l60e rebuild I've done anything or certain parts I need to pay extra special attention to? I plan on doing a full rebuild that will be worthy of 600rwhp haven't come up with a list of what parts Im gonna use any suggestions is appreciated. Been looking at trutrans kits. There was no big metal parts or shavings really in the pan a lot of very fine brass tho and what looked like clutch fibers. I had nothing in any gear but when I checked the fluid not running and running the level did change
Thanks
