For all other customers that describe the symptom condition above or if the technician finds the DTC, perform normal published service information for detailed diagnostics and repair procedures.**

NOTE: Due to the unique nature of this repair, a TechTube training video is available to help guide technicians through the repair process. Please refer to course TT02002 anytime during this repair for additional assistance.

1. Remove the transmission. Refer to detailed removal instructions in DealerCONNECT/TechCONNECT Service Information Section 21 – Transmission and Transfer Case> Automatic – 948TE> Removal> FWD, AWD/4WD.

WARNING:Always wear safety glasses when cleaning, disassembling and assembling the transmission/transaxle. Contents of the transmission/transaxle can become projectiles (e.g., springs, snap-rings, as well as metal and other debris). Failure to wear safety glasses may result in severe personal injury.

CAUTION: Tag all snap rings, thrust washers, washers, spacers and thrust bearings, etc. during disassembly for quick identification and assembly. Failure to follow these instructions may cause damage to the transmission.

NOTE: Before disassembling the transmission, wash the transmission with a suitable solvent and/or pressure washer to remove oily grime and loose dirt. Place the transmission on a clean work surface with ample fluid drainage capacity or absorbency.

2. With the transmission secured on a suitable work surface, remove the torque converter and drain.
3. Remove the transmission drain plug, production fill plug and torque converter pressure port plugs from the bell housing and drain all transmission fluid. See (Fig. 1), (Fig. 2), and (Fig. 3).

CAUTION: Care must be taken when removing the valve body to avoid damage to the Transmission Range Sensor (TRS) and speed sensor electrical harness.

7. Using a suitable prying tool, pry the valve body away from the fluid transfer/adapter tubes.
8. Taking care not to damage the wiring harness, set the valve body aside to gain access to the TRS and speed sensor bolted to the transmission housing.
9. Remove the TRS and speed sensor retaining bolts and remove the sensors.
10. Set the valve body aside in a clean area until reinstallation.
11. From around the perimeter of the transmission, remove the bellhousing to transmission housing retaining bolts (Qty 17).
