REMOVAL & INSTALLATION

WARNINGVehicle is equipped with Supplemental Inflatable Restraint (SIR) system. When servicing vehicle, use care to avoid accidental air bag deployment. SIR system-related components are located in various locations throughout interior and exterior of vehicle, depending on application. Do not use electrical test equipment on or near these circuits. If necessary, deactivate SIR system before servicing components. See appropriate AIR BAG DEACTIVATION PROCEDURES article in GENERAL INFORMATION.
CAUTIONWhen battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See appropriate COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
  1. Remove center exhaust pipe.
  2. Remove drive shaft. See appropriate DRIVE SHAFTS & UNIVERSAL JOINTS article in DRIVELINE/AXLES.
  3. On models equipped with AWD, remove transfer case. See appropriate TRANSFER CASE article in TRANSAXLES/TRANSMISSIONS.
  4. On all models, remove rear oil seal using flat-bladed screwdriver. Use care to not scratch rear extension assembly on RWD models or adaptor case assembly on AWD models. (Scheme 8)
  5. To install, reverse removal procedure. Use drift to drive rear oil seal into rear extension (on RWD models) or adaptor case (on AWD models) until it is flush. Apply ATF to rear oil seal upon installation. Tighten all nuts and bolts to specification.

Removal (RWD)

  1. Disconnect negative battery terminal.
  2. Drain transmission fluid through drain plug.
  3. Remove front suspension member. See appropriate FRONT SUSPENSION article in SUSPENSION.
  4. Remove front exhaust pipe and center exhaust pipe.
  5. Remove rear drive shaft. See appropriate DRIVE SHAFTS & UNIVERSAL JOINTS article in DRIVELINE/DIFFERENTIALS.
  6. Remove oil pan and oil pan gasket.
  7. 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 friction 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.
  8. Support transmission with transmission jack. When setting transmission jack, place wooden blocks to prevent from damaging control valve with TCM and transmission case.
  9. Remove rear engine member.
  10. Remove tightening bolts for rear extension assembly and transmission case. (Scheme 9)
