1	Output Shaft Thrust Bearing
2	Output Carrier Assembly & Output Shaft Assembly CAUTION: Apply automatic transmission fluid (ATF) to the inside diameter of the output shaft seal before installing the output shaft assembly into the case. Failure to lube the seal may cause the seal to roll during output shaft installation, which will result in transmission damage.
