New ATSG 700R4 4L60 update supplement rebuild book

GM 700-R4 Transmission Update Handbook covers engineering changes that have occurred from 1987 to 1991, parts affected by the change, interchangeability, and part numbers. A must for 700-R4 rebuilders.

This manual is a supplement to the 'blue' rebuild book that we sell and should be used in conjunction with that book. If you do not have the blue book, we suggest that one be purchased before this supplement.
