Item 3 UD Inner Lip Seal

Leaking lip seals cause DTC 36 with a 51. This delay will be seen from N to OD (forward range only). Additionally, this condition may cause launch shudder. When overhauling the transaxle, make certain to replace the UD inner lip seal and replace the L - R inner and outer seals along with the piston retainer.

Background: The original UD inner seal was made from AEM which had the same characteristics as the original L - R seals. The UD seal retained the lip seal design but was changed to an FKM material. The FKM UD lip seal was implemented in transaxles with a build date of XXXX-1965-XXXX and greater. FKM UD lip seals are currently being used and are the seals of choice.

NOTE:
THE L - R SEALS MUST BE CHANGED WITH THE UD SEAL. THE REASON IS THE L - R SEAL WILL BE AEM AND MUST BE CHANGED TO FKM.

NOTE:
THE UD OUTER SEAL USED IN 1989 MODEL YEAR TRANSAXLES IS FATTER THAN THOSE USED IN 1990 MODELS AND LATER. MAKE SURE THE PROPER SEAL IS SELECTED FROM THE KIT FOR THE VINTAGE OF TRANSAXLE BEING WORKED ON.
