Two problems related to transmission failure have been reported for the 1996 Chevrolet Silverado. The most recently reported issues are listed below.
Z71 truck transmission failed at 55,000 miles. Gm states that my vehicle is in excellent condition & that there was nothing that I did to cause the failure. Gm service bulletin (doc. #225207) states that the vcm can cause erratic line pressure with the 4l60-e transmission. Although the bulletins are for tech. Info only, this service bulletin documents a known pre-existing defect that can "lead" to premature transmission failure due to the vcm communicating intermittent, erratic, unstable line pressure. The bulletin addresses the problem & potential "failure or damage" versus being informative & tools needed for the job. Because consumers are not notified of bulletins, they end-up paying for these repairs out of pocket, never knowing they stem from factory defects & could be repaired for little or nothing. Notification precludes additional problems & expense that could be covered by the warranty or hidden warranty (so called good will program).
I was told that transmission failed because a modifacation was not made . Why was I not notified ?.
