ISSUE:
Some vehicles may have a "Delayed" and/or "Intermittent" No Upshift (1-2). This commonly occurs during initial drive away from extended parking.
Difficult to depress accelerator pedal concerns can accompany the No Upshift symptom or be a stand alone concern. The transaxle performs normally for
some time after it corrects itself. The issue is related to the transaxle TV plunger position at idle.
