Installation

Complete reassembly up to the low reverse friction pack.  Discard the anti-rattle spring to the scrap bin.  Then remove the Allen-Head screws from your Center Support Case Saver, which will remove the reinforced plate.  Install the center support.  Install the snap ring and new plate.  Line up the holes then install the Allen-Head screws with blue Loctite to max 12-ft/lbs.

Please Note: For installing the heavy duty center support on 4L60E/700R4, you need a 0.030 shim under the output rear ring gear.  Also, if you choose to install the anti rattle spring, grind approximately 1/16'' off the lug on the reinforced plate where it contacts the anti-rattle spring.
