Automatic Transmission Control Module problems of the 2002 Volvo XC70

Our 2002 Volvo Xc70 has a tendency to jerk ?violently? forward ?shift flare? and harsh shifting problems at low and high speeds without warning and has done so on several occasions while riding with our family; frightening everyone in the vehicle and potentially causing a serious accident. The frequency has increased over the past year to the point we are unable to operate the vehicle without serious risk of injury or accident. We were denied warranty service by a south atlanta Volvo dealer (that has since gone out of business) and by Volvo north America during the warranty period. There are literally thousands of internet postings with the same complaints. Namely, there are several primary issues including but not limited to the ecu brain of the car malfunctioning, software malfunctions and tcm malfunctioning. The jerking is very freighting and could send one to the hospital with severe neck and nerve injury. We have contacted Volvo north America, Volvo worldwide and parent company Ford motors. The vehicle had an extended warranty contract that was breached by an authorized dealer and by Volvo north America.

Transmission on my 2002 Volvo v70 xc started to exhibit shift flare and harsh shifting that gave control problems at low and high speeds. Dealer downloaded new transmission software and inspected and cleaned the tcm (throttle control module). Tcm was not replaced as dealer claimed it was not part of recall program. Have driven the car for the last few weeks with no noticeable difference in shifting problems. Contacted Volvo north America's consumer support to file report this morning. Visited several online forums concerning the issue and found thousands of posts regarding similar problems with cars using asin-warner aw55-50 gearbox. Especially helpful were posts at Volvo- forums. Com and swedespeed. Com. One post was from used Volvo dealer complaining of the effect on his business in 2001-2003 Volvo cars saying that the problem was worse than the etm recall issue. This is a serious problem effecting the safety of thousands of Volvo drivers. Volvo needs to correct the problem.
