Installation Procedure

NOTE:
  • The automatic transmission flex plate does not use a locating pin for alignment and will not initially seat against the crankshaft flange or spacer, if applicable, but will be pulled onto the crankshaft by the automatic transmission flex plate bolts.
  • This procedure requires a three stage tightening process to properly seat the automatic transmission flex plate.
