1997 & up 4L80E's have a smaller/weaker Overdrive Roller Clutch, Why GM did this is a mystery. I buy ALL the early 4L80E cores I can....Even European versions & harvest the OD Carrier, Roller Clutch, & Overrun Housing out of them.
This particular piece is from a 1996 4L80E from behind a 6.0L V12 Jaguar that had under 40,000 miles. All I did was replace the Bushing & the Overrun Frictions.
This pic highlights the difference between the OD Roller Clutch that was in this unit (Left) & the larger/more robust Roller Clutch found in the Jaguar OD assembly on the right.
