FIGURE 1 - INPUT SHAFT OIL SEAL RINGS
BULLETIN COVERS:
An intermittent slip in forward and/or reverse when the transaxle is cold may be caused by leaking Input Shaft Oil Seal Ring(s) (624). This may be due to
one or more undersized Input Shaft Oil Seal Ring(s) that seal the Input Clutch and 3rd Clutch feed holes. The transaxle may slip less in Reverse or
Manual Lo (D1) ranges (due to boosted line pressure) than in Overdrive (D4), Drive (D3), or Manual Second (D2).
SERVICE ACTION: (Figure 1)
Disassemble the transaxle, remove the Shaft and Housing Assembly (626) and inspect the Input Shaft Oil Seal Rings (624) while in the grooves. The
rings should take up most of the groove width. If the ring(s) only take up about half of the groove width then replace them with rings from the package
listed under Service Parts Information. Follow procedures outlined in the 1989 Service Manual Unit Repair Section.
Important:
Inspect for burned Input and 3rd Clutch Plate Assemblies. Replace if necessary.
