CLUTCH ASSEMBLY
Some 1980 thru 1983 THM 125/125-C transaxles may exhibit a no reverse or neutral to reverse delayed engagement condition.
To correct these conditions, two changes in the low and reverse clutch assembly were introduced in late March 1983. The low and reverse piston
assembly is being produced with a third design lip seal retainer and an oil displacement insert was added to the low and reverse clutch assembly. This
insert displaces oil and quickens the apply of the low and reverse clutch.
When servicing any 1980 thru 1983 THM 125/125-C transaxle for a no reverse or a neutral to reverse delayed engagement, refer to the following chart:
