1 Automatic Transmission Control Module problem of the 2001 Saturn LS

Failure Date: 04/30/2009

I own an 2001 Saturn l-33, with 38,280 miles. On two occasions the service light (not the service engine light came on, and when this occurred, the transmission would shift harshly. On 04-30- 2009, I had started the car, which had no been used that day, I was sitting somewhat sideways in the drivers seat talking to my father, when the auto when the auto went into reverse by itself, and dragged me across the street, hitting a block wall. I got up and into the auto, and noticed the shift lever was still in "park". I found a websight "the Saturn forum" wherein other Saturn l-300 owners had the same problem with the service light coming on etc. As far as I know, Saturn has not sent out a service bulletin, or re-call on this problem. I also found out the problem might be due to "pinched" wiring going to the "transmission control module. I am hesitant in taking the auto to the dealer for repair as I was injured, and I might re-tain legal council in this matter. I think Saturn should be notifying people of the possible hazard involved in this auto.

2 Automatic Transmission Control Module problem of the 2000 Saturn LS

Failure Date: 01/03/2006

2000 Saturn Ls, 6 cylinder, had slippage of the transmission followed by the service light. By the time I reached the dealer the car was bucking and felt like I was repeatedly being hit from behind. The mechanic told me it was the sensor module and when it broke the pressure was full open and that's what caused that problem. Subsequently the light came on again, the transmission slipped and the module was replaced again. It then happened a 3rd time and the module was replaced again. When driving it home after repair, I noticed that the trans was slipping a little. Took it back into the shop, they say they can't rip down the trans unless the light comes on and it gives codes again. I only have 11,000 miles on the warranty. I believe there is another problem with the transmission.
