Revolution Sensor: Removal
- Disconnect negative battery terminal.
- Drain transmission fluid through drain plug.
- Remove front exhaust pipe and center exhaust pipe.
- Remove rear drive shaft. See DRIVE SHAFTS & UNIVERSAL JOINTS article in DRIVELINE/AXLES.
- Disconnect heated oxygen sensor No. 2 harness connector.
- Remove oil pan and oil pan gasket.
- Check foreign materials in oil pan to help determine causes of malfunction. If transmission fluid is very dark, smells burned, or contains foreign particles, the frictional material (clutches, bands) may need replacement. A tacky film that will not wipe clean indicates varnish build up. Varnish can cause valves, servo, and clutches to stick and can inhibit pump pressure.
- Support transmission with transmission jack. When setting transmission jack, place wooden blocks to prevent from damaging control valve with TCM and transmission case.
- Remove rear engine crossmember. See Fig 2.
- Remove tightening bolts from rear extension assembly and transmission case. See Fig 3.
- Tap rear extension assembly with soft hammer.
- Remove rear extension assembly from transmission case (with needle bearing).
- Disconnect revolution sensor connector. Use care to not damage connector. See Fig 4.
- Straighten terminal clips to free sensor harness then remove clips.
- Remove revolution sensor from transmission case. See Fig 1.
NOTE:
If frictional material is detected, replace radiator after repair of A/T or flush transmission fluid from oil cooler. See OIL COOLER FLUSHING (2004) .
CAUTION:
DO NOT subject sensor to impact by dropping or hitting it. DO NOT disassemble. DO NOT allow metal filings, etc., to get on the sensor's front edge metallic area. DO NOT place in an area affected by magnetism.
