2000 Chevrolet Express 3/4 Ton Van V8-5.7L VIN RSECTION 36. Internal Transmission Speed Sensor Rotor Replace
Removal Procedure
^ Tools Required
- J 8433 Speedometer Gear Puller
- J 21427-01 Speedometer Gear Puller (Adapter)
- J 36352 Speed Sensor Rotor Installer
1. Inspect the internal transmission speed sensor rotor (699) for cracks or damaged teeth.
2. Inspect all splines on the output shaft (687) for cracks or damaged splines.
3. Remove the output shaft seal (691) and the output shaft sleeve (690) (model dependent).
4. If the internal speed sensor rotor (699) is damaged, replace it.
5. Using J 8433 with J 21427-01, remove the internal speed sensor rotor (699) from the output shaft (687).
Installation Procedure
Important: Do not re-use an internal speed sensor rotor that has been removed.
1. Slip a new internal speed sensor rotor (699) over the output shaft splines.
2. Install the J 36352-4 in the groove on the output shaft (687).
3. Place the J 36352-6 on the output shaft (687). Press on the J 36352-6 until it contacts the J 36352-4 in the window (the J 36352-4 will be a positive stop for the J 36352-6).

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
