Note:
As of March 22, 2006, this DTB must not be performed on the following vehicles which are covered under Service Campaign No. 2006020008.
Combining this DTB with the above referenced Campaign will result in a charge back of this DTB.
If you receive customer reports in the above model vehicles that the automatic transmission is leaking oil in the area of the electric connection,
secondary concerns may be oil in the wiring harness, perform the below remedy to resolve.
1. Clean the transmission in the affected area and replace the electrical connector and the related 0-rings.
Note:
The electrical connector may only be assembled/disassembled when transmission oil temperatures are less than 50 degrees C in order to prevent
damage to the conductor plate.
2. If there is transmission oil in the wiring loom, wipe dry and blow out the plug at the transmission and ECU connections. The contacts can be
cleaned with commercially available contact cleaner.
Note:
When connecting the wiring harness to the transmission, ensure that the harness is routed in a tension free path (Figure 1) and that no tension is
applied to the electrical connector from the harness (Figure 2).
