A/T - No Reverse, Neutral to Reverse Delayed Engagement
Number 83-T-56 Section 7 Date 09/83Subject: NO REVERSE OR NEUTRAL TO REVERSE DELAYED ENGAGEMENT - 1980-1983 THM 125/125C
Some 1980-1983 THM 125/125C transaxles may exhibit a no reverse or neutral to reverse delayed engagement condition..
Figure 1:
Figure 2:
Figure 3:
To correct these conditions, two changes in the low and reverse clutch assembly (see Figure 1 below) were introduced in late March, 1983. The low and reverse piston assembly is being produced with a third design lip seal retainer (see Figure 2 below) and an oil displacement insert (see Figure 3 below) 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 1980-1983 THM 125/125C transaxle for a no reverse or a neutral to reverse delayed engagement, refer to the following chart:
