Caprice V8-307 5.0L (1987)
FIGURE 2
A new turbine shaft with a ball capsule entered production for the 200C transmission (Figure 1). Transmissions produced between October 8, 1986
(Julian date 281) and December 15, 1986 (Julian date 349) may inadvertently have had a plug left in the pump cover (refer to Figure 2, item 222). If the
plug is left in, a slightly slower torque converter clutch (TCC) apply may result. This slightly slower TCC apply is not a durability concern.
When installing a Neutral/Drive shift package, as referenced in Dealer Service Bulletin 87-149 (Section 7A) dated May 1987, or when servicing a pump
on a THM 200C built between the above time frames, make sure the plug is removed from the pump cover. The new turbine shaft assembly with ball
capsule is included in the Neutral/Drive shift package.
