Camaro V6-173 2.8L (1983)
Beginning July 15, 1983 (Julian Date 169), all 700-R4 transmissions were produced using a new oil pump cover (Figure 1) and a new
pump to case gasket (Figure 2), that prevents transmission oil from exhausting out the breather during harsh deceleration during sharp
turns..

These service packages contain both a new oil pump cover and a new pump to case gasket.
NOTICE:
The new pump to case gasket cannot be used with the past oil pump cover. The past pump to case gasket can be used with
the new oil pump cover, but oil will continue to exhaust out the breather.
Refer to your service manual for disassembly and reassembly procedures.
