Summary

Summary: manufacturer claims most reports are a shift-flare condition ofhigher engine speeds during the no-load shifting time interval.this claimdoes not appear to be substantiated by the reports.reports do not followthe typical scenario of sudden acceleration occuring when the vehicle isplaced into a driving mode.many reports occur when shifting into any gearat any speed.also some reports of severe engine damage.analysis: although there appears to be a design flaw in the speed controlloop, most of the complaints occur at speeds which allow transmission dis-engagement.in addition, this tends to be an intermittent type of failurewhich is hard to trace to a single source/cause/component, although the isamotor has been cited by several of the consumers and field representatives.status: c-memo draft forwarded to (h) 6/16/87.===
