1998 4L80E year notes for techs
- Valve body (1997-2003): Second-generation VB for center-lube case: lube hole relocated, no two small holes on upper right. (source)
- Internal harness (1994-2003): Rostra 350-0032 / GM 24222798 internal harness (temp sensor in harness); fits 1994-2003 natively and 1991-1993 only if the external connector is updated. (source)
- Pump (1997-2003): Pump body redesigned (bridge in cooler passage, casting 24205779, wider bushing; retro-fits back to 1991, so the body is effectively '91-up). (source)
- Drums and shells (1997-1998): Center-lube redesign: new center support, second-design sun gear shaft (shortened bushing journal, used only 1997-98), other internal hard parts redesigned. (source)
- Clutches (1996-1998): Same counts (RGPZ-010 '96-on: 3 overrun, 4 fourth, 4 intermediate, 10 forward/direct) (source)
- Band (1996-1998): Low/Reverse servo redesigned (Sonnax '96-later piston 34914-02 and spacer kit 34528-01K). (source)
- Case (1997-2003): Case type 2: return cooler line moved toward center of case into a center-support seal (center lube); front boss left unmachined and hole blocked. (source)
- Switches and sensors (1995-2009): External NSS / MLPS on selector shaft; long manual shaft (Sonnax 38511-04K '95-later). (source)
