C 2500 3/4 Ton Pickup 2WD L6-292 4.8L VIN T 1-bbl (1982)
FIGURE 2 - Stator Shaft Sleeve
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 (Figure 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. 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 numerous 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.
