This bulletin is being updated to add model years and change a special tool reference in Step 10. Please discard Corporate Bulletin Number
03-07-30-022 (Section 07 - Transmission/Transaxle).
The purpose of this bulletin is to provide updated service information regarding transaxle oil cooler flushing for VTi transaxles. The VUE VTi transaxle
cooler lines contain a temperature sensitive bypass valve. This valve prevents the flushing of the oil cooler using the existing oil cooler flushing adapters.
In order to flush the VUE VTi transaxle, it is necessary to make two adapter lines and fitting from the existing oil cooler lines. After performing a
transaxle oil cooler flush, new oil cooler lines must be installed. This bulletin provides the procedure for creating the two adapter lines and the fitting as
well as the oil cooler flushing procedure.
Service Procedure
1.
Position the vehicle on hoist and raise the vehicle. Refer to Lifting, Jacking and Support Points in the General Information section of the Saturn
VUE Service Manual or SI.
2.
Drain the transaxle fluid. Refer to Transaxle Fluid Replacement in the VT25-E On-Vehicle section of the Service Manual or SI.
3.
Remove the transaxle oil cooler lines from the transaxle and the oil cooler.
4.
Install the oil cooler lines into a vise and cut the two lines as shown in illustration. (The cooler end of the oil cooler lines will be used in later steps.
Discard the transaxle end of the oil cooler line assembly.)
Important:
A 5/16 in (0.79 cm) outside diameter brake pipe must be obtained from a local parts supplier to perform the cooler flush procedure.
