This TSB article is being republished in its entirety to correct the part number for the Rear Lube Tube.
ISSUE:
The rear lube tube and seal and the planetary support have been redesigned for some 1993 model AX4S/AXODE transaxles. This was done to improve lubricant flow to the planetary gears. The redesigned parts are NOT interchangeable with previous design levels. Further, the new seal, tube and planetary support MUST be used together or damage to the planetary gears will result. The new design includes the following changes:
^ A new rear lube seal that is now located in the planetary support assembly and not in the transaxle case. The new seal is reusable if it has not been damaged during disassembly.
^ A revised planetary support, incorporating the new rear lube seal.
^ A new rear lube tube which has a longer, smaller-diameter end to pass through the case into the rear lube seal.
ACTION:
If service is required on an AX4S/AXODE transaxle that has the new design rear tube seal located in the planetary support assembly, do NOT install the previous design rear lube seal in the transaxle case. If the rear lube tube is replaced on a unit with the new seal, use the new style tube with the longer end.
Use the following service tips when making planetary gear and rear lube tube repairs to AXODE and AX4S transaxles (Figure 1):
^ The new design rear lube tube and seal and planetary support may be used on any 1991 or 1992 AXBDE transaxle, however all three parts MUST be used together.
^ If the 1991 or 1992 unit does not already have the new crossover design lube tubes, the differential/speedo lube tube must also be changed.
^ If replacement of the planetary support assembly is required on a 1991 or later AXODE transaxle, inspect the new planetary support assembly to see if it has the new design rear lube tube seal. If it does, you must install the new rear lube seal and use the new rear lube tube.
CAUTION:
DO NOT INSTALL A REAR LUBE SEAL IN THE TRANSAXLE CASE WHEN USING THE NEW DESIGN LUBE TUBE AND SEAL.
NOTE:
THE NEW DESIGN LUBE TUBE SHOULD BE INSTALLED INTO THE REAR LUBE SEAL FIRST AND THEN PRESS THE OTHER END INTO THE CASE.
^ The new design parts may NOT be used on 1986-1990 model AXOD transaxles because the new design requires a crossover rear lube tube which is not available for transaxles still using a governor circuit. If the planetary support assembly is replaced in 1986-1990 model AXOD units, the old design MUST be used (Figure 2).
^ The old design planetary support may be used on any AXOD or AXODE transaxle, but extreme care must be taken to install the old rear lube seal and the correct rear lube tube. If not installing the new design parts, 1991 and 1992 model units should still be updated with the crossover design lube tubes (refer to TSB 92-26A-1), but the end of the rear lube tube must have the old uniform diameter end (Figure 3).
