Built a few autos in the past and they all worked fine, figure I'll give my 4l60e a shot since the clutches finally went at 134k. So far I've come up with this small list of items

Performance Kit from BulkPart.com Link

Also includes this kit with it

Beast shell

Sonnax Super Servo/4th Gear

1-2 Super Servo

This list is only a baseline assuming no hard parts need to be replaced. The trans will be used in a street strip vehicle with mods in sig. Any other improvements that anyone can suggest I should make while the trans is apart will be greatly appreciated.
