band service package(s) (that includes an instruction sheet about the non-selective band apply pin). The proper band apply pin must be ordered
separately.
NOTICE:
If replacing a 1-2 band with the new 1-2 band listed in this bulletin, the 1-2 band stop (on models so equipped) must be removed prior to installing the
band. The 1-2 band stop, if not removed, would cause the new 1-2 band to remain partly applied, distressing the 1-2 band. Reference Service Bulletin,
90-7440-8.
IMPORTANT:
The new reverse band also has the new friction material that will help decrease reverse engagement concerns. Reference Service Bulletin 90-7440-12.
DATE OF PRODUCTION CHANGE:
Beginning July 2, 1990 (Julian Date 183), all 1991 Hydra-Matic 4T60 transaxles were built with the new 1-2 and reverse band assemblies.
SERVICE PARTS INFORMATION:
The new bands will replace the previous bands.
