- Vehicles having transmissions with transmission build dates after December 6, 2005 use the same size, shorter feed tube in the primary, secondary and main pressure feed tube locations.
Be sure to note what size the feed tubes are when removed and install them in the same case hole location they were removed from.
Short and long feed tubes cannot be interchanged because CVT cases built after December 6, 2005 that use the shorter feed tube in all 3 locations have shallower case holes in the primary and secondary feed tube locations. Putting the longer feed tubes in these cases will result in cross leakage when the mechatronic assembly is installed. Putting shorter feed tubes in a location that used the longer hole may also result in a cross leak when the mechatronic assembly is installed from the tube being pushed farther down and not sealing.
For transaxles built before December 6, 2005, lubricate the new O-ring seals with clean transmission fluid and install the O-ring seals on the feed tubes.
- Install new O-ring seals on the inside and outside clutch (manual valve) supply feed tube.
- Install new O-ring seals on the primary pressure feed tube, secondary pressure feed tube and main (pump) pressure feed tube.
