Firebird V8-305 5.0L (1982)
Figure 2
Important:
A hairline crack in the turbine shaft is not always detected by visually inspecting the shaft. To determine if the shaft is
cracked, inspect the stator shaft sleeve for possible score marks in the inner diameter (fig. 2). If scoring is found, the
probable cause is a crack in the turbine shaft which opens under torque conditions and produces the scoring and burned
clutch packs. If this condition is found, replace both the input housing and shaft assembly and the oil pump assembly
complete. Due to recent changes in the oil pump cover and pump body castings, these parts are serviced as an assembly for
1982 through 1984.
2.
Oil pump assemblies, input housing and shaft assemblies, and converters can be purchased separately as shown in the following charts #1, #2, and
#3, respectively (See page 3, 4, 5). However, any transmission built prior to this change (1982, 1983, or 1984 not identified by a "T") must use the
part numbers shown in the column marked "before Julian Date 107". Any 1984 transmission built after this change (identified by the letter "T")
must use the part numbers in the column marked "after Julian Date 107".
3.
Due to the changes made on the above parts, those shown for use prior to the change must not be interchanged with those shown for use after the
change. Interchanging these parts will result in conditions such as:
A.
Interference fits
B.
Loose fits
C.
No drive
D.
Possible repeat cracks in the turbine shaft
E.
Future confusion if the transmission should require additional service
