Condition/Concern
Some customers may comment on an automatic transmission fluid leak. Upon further investigation, the technician
may find fluid leaking from the torque converter housing and the torque converter seal.
Recommendation/Instructions
Important: It is recommended that a new torque converter seal be installed any time the transmission is removed
from the vehicle for any reason. DO NOT remove the transmission from the vehicle to replace the torque converter
seal unless there is a torque converter seal leak or other internal transmission repairs are needed.
If diagnosis determines that the leak is the torque converter seal, the seal should be replaced. A torque converter
seal that makes use of a more robust sealing material is now available.
This revised seal is also included in the automatic transmission seal kit P/Ns 24269583, 24267774, 24267569 and
24267776.
Note: DO NOT order a seal kit unless it is necessary to remove the transmission from the vehicle to perform internal
transmission repairs.
