ISSUE:
There may be an intermittent no 1-2 upshift or a delayed 1-2 upshift. This usually occurs during the initial drive away from extended parking. The
transaxle performs normally for some time, after it warms up. The technician may be unable to verify the symptom and the customer may be unable to
demonstrate the concern at will. This condition is caused by the TV modulator spring turning around in the 1-2 shift bore.
ACTION:
Install a new TV modulator spring retainer plate which has a dimple on the retainer to keep the spring from turning around in the 1-2 shift bore. Refer to
the following procedure for service details.
1.
Remove the components (except valve) from the 1-2 shift bore, Figure 1.
a.
Remove the outside plug, valve and spring.
b.
Plug or cover the end of the bore before removing the old retainer plate because the spring is compressed against the plate.
2.
With the valve and spring installed, compress the spring slightly with a thin bladed screwdriver.
a.
While compressing the spring, slide the new TV modulator spring retainer plate (F23Z-7F194-A) down into position, Figure 1. The retainer
plate has a narrow screwdriver access slot and small centered bump.
b.
Install with the narrow slot going over the screwdriver and the bump going into the spring.
